Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach,
so add our own XSAVE{,OPT,S} code and use it for Linux 5.16.
Please note that this differs from previous behavior in that it
won't handle exceptions created by XSAVE an XRSTOR. This is sensible
for three reasons.
- Exceptions during XSAVE and XRSTOR can only occur if the feature
is not supported or enabled or the memory operand isn't aligned
on a 64 byte boundary. If this happens something else went
terribly wrong, and it may be better to stop execution.
- Previously we just printed a warning and didn't handle the fault,
this is arguable for the above reason.
- All other *SAVE instruction also don't handle exceptions, so this
at least aligns behavior.
Finally add a test to catch such a regression in the future.

There's no need to make the platform ops dynamic dispatch.
This change replaces the dynamic dispatch with static calls to the
platform-specific functions.
To avoid name collisions, prefix all platform-specific functions
with `zvol_os_`.
I actually find `zvol_..._os` slightly nicer to read in the calling
code, but having it as a prefix is useful.
Advantage:
- easier jump-to-definition / grepping
- potential benefits to static analysis
- better legibility
Future work: also prefix remaining `static` functions in zvol_os.c.

`configure` now accepts `--enable-asan` and `--enable-ubsan` switches
which results in passing `-fsanitize=address`
and `-fsanitize=undefined`, respectively, to the compiler. Those
flags are enabled in GitHub workflows for ZTS and zloop. Errors
reported by both instrumentations are corrected, except for:
- Memory leak reporting is (temporarily) suppressed. The cost of
fixing them is relatively high compared to the gains.
- Checksum computing functions in `module/zcommon/zfs_fletcher*`
have UBSan errors suppressed. It is completely impractical
to enforce 64-byte payload alignment there due to performance
impact.
- There's no ASan heap poisoning in `module/zstd/lib/zstd.c`. A custom
memory allocator is used there rendering that measure
unfeasible.
- Memory leaks detection has to be suppressed for `cmd/zvol_id`.
`zvol_id` is run by udev with the help of `ptrace(2)`. Tracing is
incompatible with memory leaks detection.

This checking breaks KMSAN since it effectively loads from uninitialized
memory to see if the lock is already initialized. This happens in
dnode_cons() for example. This checking is not very useful, partly due
to UMA's memory trashing, and is already disabled for mutexes. Make
mutexes and rwlocks consistent: remove double-initialization checking
for rwlocks, and pass SX_NEW to disable the same checking in
lock_init().
No functional change intended, this affects only debug builds.
As a side note, kmem cache constructors/destructors are implemented
suboptimally on FreeBSD. FreeBSD's slab allocator, UMA, supports two
pairs of constructors/destructors: ctor/dtor and init/fini. The former
are called upon every allocation and free of an item, while the latter
are called when an item is imported or released from a zone,
respectively. That is, when a slab is allocated to a particular cache,
it is subdivided into items, and init is called on each. fini is called
when the slab is being prepared to be freed back to the system. The
intent is for them to initialize static fields such as locks, which
do not need to be initialized upon each allocation of an item.
In illumos, kmem_cache constructors/destructors correspond to UMA's
init/fini callbacks. However, in the SPL they are implemented as UMA
ctor/dtors, meaning that they get called far more often than necessary.
This may be difficult to fix, since new code may assume the kmem cache
ctor/dtors are in fact called upon each allocation/free, and there
doesn't seem to be a clear way to implement the intended semantics on
Linux.

When the eviction thread goes to shrink an ARC state, it allocates a set
of marker buffers used to hold its place in the state's sublists.
This can be problematic in low memory conditions, since
1) the allocation can be substantial, as we allocate NCPU markers;
2) on at least FreeBSD, page reclamation can block in
arc_wait_for_eviction()
In particular, in stress tests it's possible to hit a deadlock on
FreeBSD when the number of free pages is very low, wherein the system is
waiting for the page daemon to reclaim memory, the page daemon is
waiting for the ARC eviction thread to finish, and the ARC eviction
thread is blocked waiting for more memory.
Try to reduce the likelihood of such deadlocks by pre-allocating markers
for the eviction thread at ARC initialization time. When evicting
buffers from an ARC state, check to see if the current thread is the ARC
eviction thread, and use the pre-allocated markers for that purpose
rather than dynamically allocating them.

Verify that all empty sectors are zero filled before using them to
calculate parity. Failure to do so can result in incorrect parity
columns being generated and written to disk if the contents of an
empty sector are non-zero. This was possible because the checksum
only protects the data portions of the buffer, not the empty sector
padding.
This issue has been addressed by updating raidz_parity_verify() to
check that all dRAID empty sectors are zero filled. Any sectors
which are non-zero will be fixed, repair IO issued, and a checksum
error logged. They can then be safely used to verify the parity.
This specific type of damage is unlikely to occur since it requires
a disk to have silently returned bad data, for an empty sector, while
performing a scrub. However, if a pool were to have been damaged
in this way, scrubbing the pool with this change applied will repair
both the empty sector and parity columns as long as the data checksum
is valid. Checksum errors will be reported in the `zpool status`
output for any repairs which are made.
