When using cached attributes, whether or not the data cache is enabled,
fusefs must update a file's atime whenever it reads from it, so long as
it wasn't mounted with -o noatime. Update it in-kernel, and flush it to
the server on close or during the next setattr operation.
The downside is that close() will now frequently trigger a FUSE_SETATTR
upcall. But if you care about performance, you should be using
-o noatime anyway.

Basic signal tests that tests can we deliver a signal via raise() and
can we deliver one via SIGALARM asynchronously.
In addition, tests whether or not on ARM T32 (Thumb) code can interrupt
A32 (normal) and vice versa.
While this test is aimed at ensuring basic qemu signals are working,
it's good to have in the base.

coredump_phnum intends to generate a core file with many PT_LOAD
segments. Previously it called mmap() in a loop with alternating
protections, relying on each mapping following the previous, to produce
a core file with many page-sized PT_LOAD segments. With ASLR on we no
longer have this property of each mmap() following the previous.
Instead, perform a single allocation, and then use mprotect() to set
alternating pages to PROT_READ.

AES-CBC OpenSSL assembly is used underneath.
The glue layer(ossl_aes.c) is based on CHACHA20 implementation.
Contrary to the SHA and CHACHA20, AES OpenSSL assembly logic
does not have a fallback implementation in case CPU doesn't
support required instructions.
Because of that CPU caps are checked during initialization and AES
support is advertised only if available.
The feature is available on all architectures that ossl supports:
i386, amd64, arm64.
The biggest advantage of this patch over existing solutions
(aesni(4) and armv8crypto(4)) is that it supports SHA,
allowing for ETA operations.

There are two issues with the checks against VM_MAXUSER_ADDRESS. First,
the comparison should consider the values as unsigned, otherwise
addresses with the high bit set will fail to branch. Second, the value
of VM_MAXUSER_ADDRESS is, by convention, one larger than the maximum
mappable user address and invalid itself. Thus, use the bgeu instruction
for these comparisons.

Previously, only test vectors which used the default nonce and tag
sizes (12 and 16, respectively) were tested. This now tests all of
the vectors. This exposed some additional issues around requests with
an empty payload (which wasn't supported) and an empty AAD (which
falls back to CIOCCRYPT instead of CIOCCRYPTAEAD).
- Make use of the 'ivlen' and 'maclen' fields for CIOGSESSION2 to
test AES-CCM vectors with non-default nonce and tag lengths.
- Permit requests with an empty payload.
- Permit an input MAC for requests without AAD.

The DevFusePoll::access/select test would occasionally segfault. The
cause was a file descriptor that was shared between two threads. The
first thread would kill the second and close the file descriptor. But
it was possible that the second would read the file descriptor before it
shut down. That did not cause problems for kqueue, poll, or blocking
operation, but it triggered segfaults in select's macros.

If the FUSE server tells the kernel that a file's size has changed, then
the kernel must invalidate any portion of that file in cache. But the
kernel can't do that during VOP_STRATEGY, because the file's buffers are
already locked. Instead, proceed with the write.

fuse_vnop_bmap needs to know the file's size in order to calculate the
optimum amount of readahead. If the file's size is unknown, it must ask
the FUSE server. But if the file's data was previously cached and the
server reports that its size has shrunk, fusefs must invalidate the
cached data. That's not possible during VOP_BMAP because the buffer
object is already locked.
Fix the panic by not querying the FUSE server for the file's size during
VOP_BMAP if we don't need it. That's also a a slight performance
optimization.

NOTE_ABSTIME values are converted to values relative to boottime in
filt_timervalidate(), and negative values are currently rejected. We
don't reject times in the past in general, so clamp this up to 0 as
needed such that the timer fires immediately rather than imposing what
looks like an arbitrary restriction.
Another possible scenario is that the system clock had to be adjusted
by ~minutes or ~hours and we have less than that in terms of uptime,
making a reasonable short-timeout suddenly invalid. Firing it is still
a valid choice in this scenario so that applications can at least
expect a consistent behavior.
