libzfs: zfs_mount_at(): load key for encryption root if MS_CRYPT
zfs_crypto_load_key() only works on encryption roots,
and zfs mount -la would fail if it encounters a datasets that
is sorted before their encroots.

To trigger:
  truncate -s 40G /tmp/test
  dd if=/dev/urandom of=/tmp/k bs=128 count=1 status=none
  zpool create -O encryption=on -O keylocation=file:///tmp/k \
               -O keyformat=passphrase test /tmp/test
  zfs create -o mountpoint=/a test/a
  zfs create -o mountpoint=/b test/b
  zfs umount test
  zfs unload-key test
  zfs mount -la

The final mount errored out with:
  Key load error: Keys must be loaded for
    encryption root of 'test/a' (test).
  Key load error: Keys must be loaded for
    encryption root of 'test/b' (test).

And only /test was mounted

This technically breaks the libzfs API, but the previous behavior was
decidedly a bug.

cmd/zfs receive: allow dry-run (-n) to check property args
zfs recv -n does not report some errors it could.  The code to bail 
out of the receive if in dry-run mode came a little early, skipping 
validation of cmdprops (recv -x and -o) among others.  Move the
check down to enable these additional checks.

libuutil: purge unused functions
Remove vestigial uu_open_tmp().  The problems with this implementation
are many, but the primary one is the TMPPATHFMT macro, which is
unused, and always has been.

Searching around for any users leads only to earlier imports of the
same, identical file, i.a. into an apple repository (which does patch
gethrtime() into it and gives us a copyright date of 2007),
and a MidnightBSD one from 2008.

Searching illumos-gate, uu_open_tmp appears, in current HEAD, three
times: in the header, libuutil's mapfile ABI, and the implementation.

This slowly grows up to eight occurrences as one moves back to the root
"OpenSolaris Launch" commit: the header, implementation, twice in
libuutil's spec ABI, twice (with multilib and non-multilib paths) in
libuutil.so's i386 and SPARC binary db ABIs.

That's 2005, and this file was abandonware even then, it's dead code.

The situation is similar for the uu_dprintf() family of functions and
uu_dump().  Nothing in accessibly recorded history has ever used them.

Improvements to the 'compatibility' property
Several improvements to the operation of the 'compatibility' property:

1) Improved handling of unrecognized features:
Change the way unrecognized features in compatibility files are handled.

 * invalid features in files under /usr/share/zfs/compatibility.d
   only get a warning (as these may refer to future features not yet in
   the library),
 * invalid features in files under /etc/zfs/compatibility.d
   get an error (as these are presumed to refer to the current system).

2) Improved error reporting from zpool_load_compat.
Note: slight ABI change to zpool_load_compat for better error reporting.

3) compatibility=legacy inhibits all 'zpool upgrade' operations.

4) Detect when features are enabled outside current compatibility set
   * zpool set compatibility=foo <-- print a warning
   * zpool set feature@xxx=enabled <-- error
   * zpool status <-- indicate this state

Bump libzfs.so and libzpool.so versions
Bump the library versions as advised by the libtool guidelines.

https://www.gnu.org/software/libtool/manual/html_node/Updating-version-info.html

Two new functions were added but no existing functions were changed,
so we increase the version and the age (version:revision:age).

Added functions (2):
- boolean_t zpool_is_draid_spare(const char *);
- zpool_compat_status_t zpool_load_compat(const char *,
      boolean_t *, char *, char *);

Additionally bump the libzpool.so version information.  This library
is for internal use but we still want to update the version to track
major changes to the interfaces.

The libzfsbootenv, libuutil, libnvpair and libzfs_core libraries
have not been updated.

When specifying raidz vdev name, parity count should match
When specifying the name of a RAIDZ vdev on the command line, it can be
specified as raidz-<vdevID> or raidzP-<vdevID>.
e.g. `zpool clear poolname raidz-0` or `zpool clear poolname raidz2-0`

If the parity is specified in the vdev name, it should match the actual
parity of that RAIDZ vdev, otherwise the command should fail.  This
commit makes it so.

zpool import cachefile improvements
Importing a pool using the cachefile is ideal to reduce the time
required to import a pool. However, if the devices associated with
a pool in the cachefile have changed, then the import would fail.
This can easily be corrected by doing a normal import which would
then read the pool configuration from the labels.

The goal of this change is make importing using a cachefile more
resilient and auto-correcting. This is accomplished by having
the cachefile import logic automatically fallback to reading the
labels of the devices similar to a normal import. The main difference
between the fallback logic and a normal import is that the cachefile
import logic will only look at the device directories that were
originally used when the cachefile was populated. Additionally,
the fallback logic will always import by guid to ensure that only
the pools in the cachefile would be imported.

Better zfs_get_enclosure_sysfs_path() enclosure support
A multpathed disk will have several 'underlying' paths to the disk.  For
example, multipath disk 'dm-0' may be made up of paths:
/dev/{sda,sdb,sdc,sdd}.  On many enclosures those underlying sysfs
paths will have a symlink back to their enclosure device entry
(like 'enclosure_device0/slot1').  This is used by the
statechange-led.sh script to set/clear the fault LED for a disk, and
by 'zpool status -c'.

However, on some enclosures, those underlying paths may not all have
symlinks back to the enclosure device.  Maybe only two out of four
of them might.

This patch updates zfs_get_enclosure_sysfs_path() to favor returning
paths that have symlinks back to their enclosure devices, rather
than just returning the first path.

Add "compatibility" property for zpool feature sets
Property to allow sets of features to be specified; for compatibility
with specific versions / releases / external systems. Influences
the behavior of 'zpool upgrade' and 'zpool create'. Initial man
page changes and test cases included.

Brief synopsis:

zpool create -o compatibility=off|legacy|file[,file...] pool vdev...

compatibility = off : disable compatibility mode (enable all features)
compatibility = legacy : request that no features be enabled
compatibility = file[,file...] : read features from specified files.
Only features present in *all* files will be enabled on the
resulting pool. Filenames may be absolute, or relative to
/etc/zfs/compatibility.d or /usr/share/zfs/compatibility.d (/etc
checked first).

Only affects zpool create, zpool upgrade and zpool status.

ABI changes in libzfs:

* New function "zpool_load_compat" to load and parse compat sets.
* Add "zpool_compat_status_t" typedef for compatibility parse status.
* Add ZPOOL_PROP_COMPATIBILITY to the pool properties enum
* Add ZPOOL_STATUS_COMPATIBILITY_ERR to the pool status enum

An initial set of base compatibility sets are included in
cmd/zpool/compatibility.d, and the Makefile for cmd/zpool is
modified to install these in $pkgdatadir/compatibility.d and to
create symbolic links to a reasonable set of aliases.

0e6c493fec cppcheck: integrete cppcheck
In order for cppcheck to perform a proper analysis it needs to be
aware of how the sources are compiled (source files, include
paths/files, extra defines, etc).  All the needed information is
available from the Makefiles and can be leveraged with a generic
cppcheck Makefile target.  So let's add one.

Additional minor changes:

* Removing the cppcheck-suppressions.txt file.  With cppcheck 2.3
  and these changes it appears to no longer be needed.  Some inline
  suppressions were also removed since they appear not to be
  needed.  We can add them back if it turns out they're needed
  for older versions of cppcheck.

* Added the ax_count_cpus m4 macro to detect at configure time how
  many processors are available in order to run multiple cppcheck
  jobs.  This value is also now used as a replacement for nproc
  when executing the kernel interface checks.

* "PHONY =" line moved in to the Rules.am file which is included
  at the top of all Makefile.am's.  This is just convenient becase
  it allows us to use the += syntax to add phony targets.

* One upside of this integration worth mentioning is it now allows
  `make cppcheck` to be run in any directory to check that subtree.

* For the moment, cppcheck is not run against the FreeBSD specific
  kernel sources.  The cppcheck-FreeBSD target will need to be
  implemented and testing on FreeBSD to support this.

Speed up "zpool import" in the presence of many zvols
By default, FreeBSD does not allow zpools to be backed by zvols (that
can be changed with the "vfs.zfs.vol.recursive" sysctl). When that
sysctl is set to 0, the kernel does not attempt to read zvols when
looking for vdevs. But the zpool command still does. This change brings
the zpool command into line with the kernel's behavior. It speeds "zpool
import" when an already imported pool has many zvols, or a zvol with
many snapshots.

again.  That can cost a lot of time for large pools.

OpenZFS commit 28b40c8a6e set the guess at "zc.zc_nvlist_conf_size * 4"
without explanation.  On my system, that is too small.  From experiment,
x 32 is a better multiplier.  But I don't know how to calculate it
theoretically.

zpool_read_label doesn't need the full labels including uberblocks.  It

read to check for a label, speeding up "zpool import", "zpool

Extending FreeBSD UIO Struct
In FreeBSD the struct uio was just a typedef to uio_t. In order to
extend this struct, outside of the definition for the struct uio, the
struct uio has been embedded inside of a uio_t struct.

Also renamed all the uio_* interfaces to be zfs_uio_* to make it clear
this is a ZFS interface.

b6722b871b nvlist leaked in zpool_find_config()
In `zpool_find_config()`, the `pools` nvlist is leaked.  Part of it (a
sub-nvlist) is returned in `*configp`, but the callers also leak that.

Additionally, in `zdb.c:main()`, the `searchdirs` is leaked.

The leaks were detected by ASAN (`configure --enable-asan`).

This commit resolves the leaks.

Linux 5.10 compat: use iov_iter in uio structure
As of the 5.10 kernel the generic splice compatibility code has been
removed.  All filesystems are now responsible for registering a
->splice_read and ->splice_write callback to support this operation.

The good news is the VFS provided generic_file_splice_read() and
iter_file_splice_write() callbacks can be used provided the ->iter_read
and ->iter_write callback support pipes.  However, this is currently
not the case and only iovecs and bvecs (not pipes) are ever attached
to the uio structure.

This commit changes that by allowing full iov_iter structures to be
attached to uios.  Ever since the 4.9 kernel the iov_iter structure
has supported iovecs, kvecs, bvevs, and pipes so it's desirable to
pass the entire thing when possible.  In conjunction with this the
uio helper functions (i.e uiomove(), uiocopy(), etc) have been
updated to understand the new UIO_ITER type.

Note that using the kernel provided uio_iter interfaces allowed the
existing Linux specific uio handling code to be simplified.  When
there's no longer a need to support kernel's older than 4.9, then
it will be possible to remove the iovec and bvec members from the
uio structure and always use a uio_iter.  Until then we need to
maintain all of the existing types for older kernels.

Some additional refactoring and cleanup was included in this change:

- Added checks to configure to detect available iov_iter interfaces.
  Some are available all the way back to the 3.10 kernel and are used
  when available.  In particular, uio_prefaultpages() now always uses
  iov_iter_fault_in_readable() which is available for all supported
  kernels.

- The unused UIO_USERISPACE type has been removed.  It is no longer
  needed now that the uio_seg enum is platform specific.

- Moved zfs_uio.c from the zcommon.ko module to the Linux specific
  platform code for the zfs.ko module.  This gets it out of libzfs
  where it was never needed and keeps this Linux specific code out
  of the common sources.

- Removed unnecessary O_APPEND handling from zfs_iter_write(), this
  is redundant and O_APPEND is already handled in zfs_write();

Distributed Spare (dRAID) Feature
This patch adds a new top-level vdev type called dRAID, which stands
for Distributed parity RAID.  This pool configuration allows all dRAID
vdevs to participate when rebuilding to a distributed hot spare device.
This can substantially reduce the total time required to restore full
parity to pool with a failed device.

A dRAID pool can be created using the new top-level `draid` type.
Like `raidz`, the desired redundancy is specified after the type:
`draid[1,2,3]`.  No additional information is required to create the
pool and reasonable default values will be chosen based on the number
of child vdevs in the dRAID vdev.

    zpool create <pool> draid[1,2,3] <vdevs...>

Unlike raidz, additional optional dRAID configuration values can be
provided as part of the draid type as colon separated values. This
allows administrators to fully specify a layout for either performance
or capacity reasons.  The supported options include:

    zpool create <pool> \
        draid[<parity>][:<data>d][:<children>c][:<spares>s] \
        <vdevs...>

    - draid[parity]       - Parity level (default 1)
    - draid[:<data>d]     - Data devices per group (default 8)
    - draid[:<children>c] - Expected number of child vdevs
    - draid[:<spares>s]   - Distributed hot spares (default 0)

Abbreviated example `zpool status` output for a 68 disk dRAID pool
with two distributed spares using special allocation classes.

When adding test coverage for the new dRAID vdev type the following
options were added to the ztest command.  These options are leverages
by zloop.sh to test a wide range of dRAID configurations.

    -K draid|raidz|random - kind of RAID to test
    -D <value>            - dRAID data drives per group
    -S <value>            - dRAID distributed hot spares
    -R <value>            - RAID parity (raidz or dRAID)

The zpool_create, zpool_import, redundancy, replacement and fault
test groups have all been updated provide test coverage for the
dRAID feature.
