a70a59ea73 Don't attempt to disable enabled fasttrap probes in an exiting process.
There's no need to do so, and we can't hold an exiting process, so this
race can result in panics.

1eb8ad64ea In fasttrap_sigtrap(), use tdsendsignal() rather than tdksignal() to send
SIGTRAP. The latter requires that its thread argument be non-NULL, but
fasttrap_sigtrap() does not.

c0d678c9dd The DTrace harness (dtest.pl) executes DTrace scripts with the -C flag,
which causes dtrace(1) to run the C preprocessor on input scripts before
executing them. Suppress some warnings emitted by the preprocessor which are
confusing the DTrace lexer tests.

93929f253d sfxge: Separate software Tx queue limit for non-TCP traffic
Add separate software Tx queue limit for non-TCP traffic to make total
limit higher and avoid local drops of TCP packets because of no
backpressure.
There is no point to make non-TCP limit high since without backpressure
UDP stream easily overflows any sensible limit.

Split early drops statistics since it is better to have separate counter
for each drop reason to make it unabmiguous.

Add software Tx queue high watermark. The information is very useful to
understand how big queues grow under traffic load.

76c8553679 sfxge: Remove extra cache-line alignment and reorder sfxge_evq_t
Remove the first member alignment to cacheline since it is nop.
Use __aligned() for the whole structure to make sure that the structure
size is cacheline aligned.
Remove lock alignment to make the structure smaller and fit all members
used on event queue processing into one cacheline (128 bytes) on x86-64.
The lock is obtained as well from different context when event queue
statistics are retrived from sysctl context, but it is infrequent.
Reorder members to avoid padding and go in usage order on event
processing.
As the result all structure members used on event queue processing fit
into exactly one cacheline (128 byte) now.

e5e313603c sfxge: Move txq->next pointer to part writable on completion path
In fact the pointer is used only if more than one TXQ is processed in
one interrupt.
It is used (read-write) on completion path only.
Also it makes the first part of the structure smaller and it fits now
into one 128byte cache line. So, TXQ structure becomes 128 bytes smaller.
