In files created/modified before 4254acb there may be a corruption of
xattrs which is not reported during scrub and normal send/receive. It
manifests only as an error when raw sending/receiving. This happens
because currently only the raw receive path checks for discrepancies
between the dnode bonus length and the spill pointer flag.
In case we encounter a dnode whose bonus length is greater than the
predicted one, we should report an error. Modify in this regard
dnode_sync() with an assertion at the end, dump_dnode() to error out,
dsl_scan_recurse() to report errors during a scrub, and zstream to
report a warning when dumping. Also added a test to verify spill blocks
are sent correctly in a raw send.

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.

If we timeout first in the test action, though, it qualifies as

timeout by default on the action and the 4h and change "functional"
usually takes.)
