Trying to 'zfs diff' a snapshot with large dnodes will incorrectly try
to access its interior slots when dnodesize > sizeof(dnode_phys_t).
This is normally not an issue because the interior slots are
zero-filled, which report_dnode() handles calling
report_free_dnode_range(). However this is not the case for encrypted
large dnodes or filesystem using many SA based xattrs where the extra
data past the legacy dnode size boundary is interpreted as a
dnode_phys_t.

Currently, the noop receive code fails to work with raw send streams
and resuming send streams. This happens because zfs_receive_impl()
reads the DRR_BEGIN payload without reading the payload itself.
Normally, the kernel expects to read this itself, but in this case
the recv_skip() code runs instead and it is not prepared to handle
the stream being left at any place other than the beginning of a
record.
This patch resolves this issue by manually reading the DRR_BEGIN
payload in the dry-run case. This patch also includes a number of
small fixups in this code path.

When a volume is created in a pool with raidz vdevs and
volblocksize != 128k, the volume can reference more space than is
reserved with the automatically calculated refreservation. There
are two deficiencies in vol_volsize_to_reservation that contribute
to this:
1) Skip blocks may be added to keep each allocation a multiple
of parity + 1. This is the dominating factor when volblocksize
is close to 2^ashift.
2) raidz deflation for 128 KB blocks is different for most other
block sizes.
See "The theory of raidz space accounting" comment in
libzfs_dataset.c for a full explanation.

OpenZFS-commit: https://github.com/illumos/illumos-gate/commit/b73ccab0Closes#8973
Problem Statement
=================
ZFS Channel program scripts currently require a timeout, so that hung or
long-running scripts return a timeout error instead of causing ZFS to get
wedged. This limit can currently be set up to 100 million Lua instructions.
Even with a limit in place, it would be desirable to have a sys admin
(support engineer) be able to cancel a script that is taking a long time.
Proposed Solution
=================
Make it possible to abort a channel program by sending an interrupt signal.In
the underlying txg_wait_sync function, switch the cv_wait to a cv_wait_sig to
catch the signal. Once a signal is encountered, the dsl_sync_task function can
install a Lua hook that will get called before the Lua interpreter executes a
new line of code. The dsl_sync_task can resume with a standard txg_wait_sync
call and wait for the txg to complete. Meanwhile, the hook will abort the
script and indicate that the channel program was canceled. The kernel returns
a EINTR to indicate that the channel program run was canceled.
Porting notes: Added missing return value from cv_wait_sig()

Accidentally introduced by dc04a8c which now takes the SCL_VDEV lock
as a reader in zfs_blkptr_verify(). A deadlock can occur if the
/etc/hostid file resides on a dataset in the same pool. This is
because reading the /etc/hostid file may occur while the caller is
holding the SCL_VDEV lock as a writer. For example, to perform a
`zpool attach` as shown in the abbreviated stack below.
To resolve the issue we cache the system's hostid when initializing
the spa_t, or when modifying the multihost property. The cached
value is then relied upon for subsequent accesses.

Strategy of parallel mount is as follows.
1) Initial thread dispatching is to select sets of mount points that
don't have dependencies on other sets, hence threads can/should run
lock-less and shouldn't race with other threads for other sets. Each
thread dispatched corresponds to top level directory which may or may
not have datasets to be mounted on sub directories.
2) Subsequent recursive thread dispatching for each thread from 1)
is to mount datasets for each set of mount points. The mount points
within each set have dependencies (i.e. child directories), so child
directories are processed only after parent directory completes.
The problem is that the initial thread dispatching in
zfs_foreach_mountpoint() can be multi-threaded when it needs to be
single-threaded, and this puts threads under race condition. This race
appeared as mount/unmount issues on ZoL for ZoL having different
timing regarding mount(2) execution due to fork(2)/exec(2) of mount(8).
`zfs unmount -a` which expects proper mount order can't unmount if the
mounts were reordered by the race condition.
There are currently two known patterns of input list `handles` in
`zfs_foreach_mountpoint(..,handles,..)` which cause the race condition.
1) #8833 case where input is `/a /a /a/b` after sorting.
The problem is that libzfs_path_contains() can't correctly handle an
input list with two same top level directories.
There is a race between two POSIX threads A and B,
* ThreadA for "/a" for test1 and "/a/b"
* ThreadB for "/a" for test0/a
and in case of #8833, ThreadA won the race. Two threads were created
because "/a" wasn't considered as `"/a" contains "/a"`.
2) #8450 case where input is `/ /var/data /var/data/test` after sorting.
The problem is that libzfs_path_contains() can't correctly handle an
input list containing "/".
There is a race between two POSIX threads A and B,
* ThreadA for "/" and "/var/data/test"
* ThreadB for "/var/data"
and in case of #8450, ThreadA won the race. Two threads were created
because "/var/data" wasn't considered as `"/" contains "/var/data"`.
In other words, if there is (at least one) "/" in the input list,
the initial thread dispatching must be single-threaded since every
directory is a child of "/", meaning they all directly or indirectly
depend on "/".
In both cases, the first non_descendant_idx() call fails to correctly
determine "path1-contains-path2", and as a result the initial thread
dispatching creates another thread when it needs to be single-threaded.
Fix a conditional in libzfs_path_contains() to consider above two.

When encryption was first added to ZFS, we made a decision to
prevent users from creating unencrypted children of encrypted
datasets. The idea was to prevent users from inadvertently
leaving some of their data unencrypted. However, since the
release of 0.8.0, some legitimate reasons have been brought up
for this behavior to be allowed. This patch simply removes this
limitation from all code paths that had checks for it and updates
the tests accordingly.

The mmp_interval test case was failing on Fedora 30 due to the built-in
'echo' command terminating the script when it was unable to write to
the sysfs module parameter. This change in behavior was observed with
ksh-2020.0.0-alpha1. Resolve the issue by using the external cat
command which fails gracefully as expected.
Additionally, remove some incorrect quotes around the $? return values.
