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.

As with FIFOs, a path descriptor for a unix socket cannot be used with
kevent().
In principle connectat(2) and bindat(2) could be modified to support an
AT_EMPTY_PATH-like mode which operates on the socket referenced by an
O_PATH fd referencing a unix socket. That would eliminate the path
length limit imposed by sockaddr_un.

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.

Test prioritisation and dummynet queues.
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
larger data transfer.
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
this will not succeed.
