Closes#4566
When ZFS partitions a block device it must wait for udev to create
both a device node and all the device symlinks. This process takes
a variable length of time and depends on factors such how many links
must be created, the complexity of the rules, etc. Complicating
the situation further it is not uncommon for udev to create and
then remove a link multiple times while processing the udev rules.
Given the above, the existing scheme of waiting for an expected
partition to appear by name isn't 100% reliable. At this point
udev may still remove and recreate think link resulting in the
kernel modules being unable to open the device.
In order to address this the zpool_label_disk_wait() function
has been updated to use libudev. Until the registered system
device acknowledges that it in fully initialized the function
will wait. Once fully initialized all device links are checked
and allowed to settle for 50ms. This makes it far more likely
that all the device nodes will exist when the kernel modules
need to open them.
For systems without libudev an alternate zpool_label_disk_wait()
was updated to include a settle time. In addition, the kernel
modules were updated to include retry logic for this ENOENT case.
Due to the improved checks in the utilities it is unlikely this
logic will be invoked. However, if the rare event it is needed
it will prevent a failure.

When partitioning a device a name may be specified for each partition.
Internally zfs doesn't use this partition name for anything so it
has always just been set to "zfs".
However this isn't optimal because udev will create symlinks using
this name in /dev/disk/by-partlabel/. If the name isn't unique
then all the links cannot be created.
Therefore a random 64-bit value has been added to the partition
label, i.e "zfs-1234567890abcdef". Additional information could
be encoded here but since partitions may be reused that might
result in confusion and it was decided against.

This issue was caused by calling `thread_init()` and `thread_fini()`

the issue the explicit calls to `thread_init()` and `thread_fini()`

I noticed during code review of zfsonlinux/zfs#4385 that the author of a
commit had peppered the various Makefile.am files with `$(TIRPC_LIBS)`
when putting it into `lib/libspl/Makefile.am` should have sufficed. Upon
further examination, it seems that he had copied what we do with
`$(ZLIB)`. We also have a bit of that with `-ldl` too. Unfortunately,
what we do is wrong, so lets fix it to set a good example for future
contributors.
In addition, we have multiple `-lz` and `-luuid` passed to the compiler
because each `AC_CHECK_LIB` adds it to `$LIBS`. That is somewhat
annoying to see, so we switch to `AC_SEARCH_LIBS` to avoid it. This is
consistent with the recommendation to use `AC_SEARCH_LIBS` over
`AC_CHECK_LIB` by autotools upstream:
https://www.gnu.org/software/autoconf/manual/autoconf-2.66/html_node/Libraries.html
In an ideal world, this would translate into improvements in ELF's
`DT_NEEDED` entries, but that is not the case because of a couple of
bugs in libtool.
The first bug causes libtool to overlink by using static link
dependencies for dynamic linking:
https://wiki.mageia.org/en/Overlinking_issues_in_packaging#libtool_issues
The workaround for this should be to pass `-Wl,--as-needed` in
`LDFLAGS`. That leads us to the second bug, where libtool passes
`LDFLAGS` after the libraries are specified and `ld` will only honor
`--as-needed` on libraries specified before it:
https://sigquit.wordpress.com/2011/02/16/why-asneeded-doesnt-work-as-expected-for-your-libraries-on-your-autotools-project/
There are a few possible workarounds for the second bug. One is to
either patch the compiler spec file to specify `-Wl,--as-needed` or pass
`-Wl,--as-needed` via `CC` like `CC='gcc -Wl,--as-needed'` so that it is
specified early. Another is to patch ltmain.sh like Gentoo does:
https://gitweb.gentoo.org/repo/gentoo.git/tree/eclass/ELT-patches/as-needed
Without one of those workarounds, this cleanup provides no benefit in
terms of `DT_NEEDED` entry generation. It should still be an improvement
because it nicely simplifies the code while encouraging good habits when
patching autotools scripts.

When checking a whole disk to see if it can be safely added to
the pool a variety of checks are done. One of those checks is
to attempt to determine the partition information and scan all
the partitions for existing filesystems.
Since ZoL contains a EFI library this partition scanning is
easy to do for GPT partitioned disks. However, for non-GPT
partitioned disks (MBR/EBR) things are a bit harder. The lack of
a convenient library means non-GPT partitioned disks will not
have all their partitions checked. For this reason, the default
behavior was to require the force option. For example:
invalid vdev specification
use '-f' to override the following errors:
/dev/vdb does not contain an GPT label but it may contain partition
information in the MBR.
However in practice requiring the force option for this case is
counter-intuitively less safe. The reason is because only the first
error is returned. By passing the force option it will suppress
this first warning and potentially others you were not aware of.
Therefore this patch inverts the default behavior for non-GPT
formated disks (unformatted, MBR/EBR, etc). If no GPT table is
detected and there is no file system detected on the provided
block device. Then it will be assumed that block device is safe
to use.
Longer term it would be nice to see MBR/EBR scanning added to
the utilities. This should be fairly straight forward to do.
However these days it's somewhat less critical because Linux
defaults to GPT partition tables for devices 2TB or larger.

Historically libblkid support was detected as part of configure
and optionally enabled. This was done because at the time support
for detecting ZFS pool vdevs had just be added to libblkid and
those updated packages were not yet part of many distributions.
This is no longer the case and any reasonably current distribution
will ship a version of libblkid which can detect ZFS pool vdevs.
This patch makes libblkid mandatory at build time and libblkid
the preferred method of scanning for ZFS pools. For distributions
which include a modern version of libblkid there is no change in
behavior. Explicitly scanning the default search paths is still
supported and can be enabled with the '-s' command line option.
Additionally making libblkid mandatory means that the 'zpool create'
command can reliably detect if a specified device has an existing
non-ZFS filesystem (ext4, xfs) and print a warning.

device names for the zpool detach/off‐
line/remove/replace commands.
-L Display real paths for vdevs resolving all symbolic
links. This can be used to lookup the current block
device name regardless of the /dev/disk/ path used
to open it.
-p Display full paths for vdevs instead of only the
last component of the path. This can be used in
conjunction with the -L flag.
This behavior may also be enabled using the following environment
variables.

ZPOOL_VDEV_NAME_FOLLOW_LINKS

All other sections use a tab, which makes them easy to parse. Only the
"scan:" section had its continuation lines indented with four spaces.
This makes them consistent with the others.

Internally ZFS keeps a small log to facilitate debugging. By default
the log is disabled, to enable it set zfs_dbgmsg_enable=1. The contents
of the log can be accessed by reading the /proc/spl/kstat/zfs/dbgmsg file.
Writing 0 to this proc file clears the log.
$ echo 1 >/sys/module/zfs/parameters/zfs_dbgmsg_enable
$ echo 0 >/proc/spl/kstat/zfs/dbgmsg
$ zpool import tank
$ cat /proc/spl/kstat/zfs/dbgmsg

Note the zfs_dbgmsg() and dprintf() functions are both now mapped to
the same log. As mentioned above the kernel debug log can be accessed
though the /proc/spl/kstat/zfs/dbgmsg kstat. For user space consumers
log messages are immediately written to stdout after applying the
ZFS_DEBUG environment variable.

Add the required kernel side infrastructure to parse arbitrary
mount options. This enables us to support temporary mount
options in largely the same way it is handled on other platforms.
See the 'Temporary Mount Point Properties' section of zfs(8)

At verbosity levels of 6 or greater, ztest_dsl_prop_set_uint64() attempts
to display the value of all properties as indexed values regardless of
whether the property is an indexed value or simply an un-indexed integer.
This patch causes the numeric value of the property to be displayed if
zfs_prop_index_to_string() fails.

This commit reworks the zed_notify_email() function to allow
configuration of the mail executable and command-line arguments.
ZED_EMAIL_PROG specifies the name or path of the executable responsible
for sending notifications via email. This variable defaults to "mail".
ZED_EMAIL_OPTS specifies command-line options passed to ZED_EMAIL_PROG.
The following keyword substitutions are performed:
- @ADDRESS@ is replaced with the recipient email address(es)
- @SUBJECT@ is replaced with the notification subject
This variable defaults to "-s '@SUBJECT@' @ADDRESS@".
ZED_EMAIL_ADDR replaces ZED_EMAIL (although the latter is retained
for backward compatibility). This variable can contain multiple
addresses as long as they are delimited by whitespace.

Build products from an out of tree build should be written
relative to the build directory. Sources should be referred
to by their locations in the source directory.
This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile. This enables the following:
$ mkdir build
$ cd build
$ ../configure \
--with-spl=$HOME/src/git/spl/ \
--with-spl-obj=$HOME/src/git/spl/build
$ make -s
This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.
Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
Makefile.am:00: but option 'subdir-objects' is disabled
