Note that these tests test the kernel TLS functionality directly.
Rather than using OpenSSL to perform negotiation and generate keys,
these tests generate random keys send data over a pair of TCP sockets
manually decrypting the TLS records generated by the kernel.

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.

soo_aio_queue() did not handle the possibility that the provided socket
is a listening socket. Up until recently, to fix this one would have to
acquire the socket lock first and check, since the socket buffer locks
were destroyed by listen(2).
Now that the socket buffer locks belong to the socket, simply check
SOLISTENING(so) after acquiring them, and make listen(2) return an error
if any AIO jobs are enqueued on the socket.
Add a couple of simple regression test cases.
Note that this fixes things only for the default AIO implementation;
cxgbe(4)'s TCP offload has a separate pru_aio_queue implementation which
requires its own solution.

We need to give the pipe sufficient bandwidth for dummynet to work.
Given that we can't rely on the TCP connection failing alltogether, but
we can measure the effect of dummynet by imposing a time limit on a

If TCP is prioritised it'll get most of the pipe bandwidth and easily
manage to transfer the data in 3 seconds or less. When not prioritised
