Originally it wasn't enabled since the hardware wasn't commonplace,
but as 10GE hardware is becoming more widely used, building the module
by default should be beneficial.

for example:
fwd tablearg ip from any to table(1)
where table 1 has entries of the form:
1.1.1.0/24 10.2.3.4
208.23.2.0/24 router2
This allows trivial implementation of a secondary routing table implemented
in the firewall layer.
I expect more work (under discussion with Glebius) to follow this to clean
up some of the messy parts of ipfw related to tables.

that it operates on lockmgr and sx locks. This can be useful for tracking
down vnode deadlocks in VFS for example. Note that this command is a bit
more fragile than 'show lockchain' as we have to poke around at the
wait channel of a thread to see if it points to either a struct lock or
a condition variable inside of a struct sx. If td_wchan points to
something unmapped, then this command will terminate early due to a fault,
but no harm will be done.

- If we panic due to spinning too long, print out a few more details
including the pointer to the mutex in question and the tid of the owning
thread.
for syscalls in kld's, even when compiled into the kernel statically.
Note that since this hardcodes the SYS_ prefix SYSCALL_MODULE_HELPER() now
only works for native ABI system calls. Those are the only ones that
used the macro anyway, and I chose to not require a second argument to the
macro to specify the prefix or audit event directly.
- Send the systrace_args files for all the compat ABIs to /dev/null for
now. Right now makesyscalls.sh generates a file with a hardcoded
function name, so it wouldn't work for any of the ABIs anyway. Probably
the function name should be configurable via a 'systracename' variable
and the functions should be stored in a function pointer in the sysvec
structure.
