5d8e635779 Re-enable WITNESS for GENERIC. Since the 5.x branch is mostly about 
SMP we'd like as much feedback as possible from users about possible
locking problems as early as possible.

To negate most of the performance impact I've also enabled
WITNESS_SKIPSPIN.  I've done this as we've been running WITNESS
over the spinlock code for a while without incident and it goes a
long way to making the performance problems of WITNESS much more
bearable.

Users who should be running current should know about turning WITNESS
off for performance reasons.

That said and done, WITNESS could/should be made into a tuneable,
but we'll leave that as an excersize to those that want to disable
it without a kernel recompile.

a59716d2d8 - Added support for receive in multiple 
descriptors. This simplifies code for jumbo frames.
- Cleaned up coding conventions to make code more unix-like.
- Cleaned up code in if_em_fxhw.c and if_em_phy.c.
  Added relevant comments.

disable interrupts completely, and stxa_sync(), which performs a store
immediately followed by a membar #Sync with interrupts disabled (this
is needed for writes to diagnostic registers).

92b98fdabe Remove WITNESS from GENERIC by default: as we grow more locks, this gets 
slower, and may be impeding adoption of -CURRENT by developers.  We
recommend turning on WITNESS by default on crash boxes, and when doing
locking development.  It will probably get turned on by default for a week
or two following any major locking commits, also.

952539e39a Allow one to specify the AWK used in the environment(commandline). 
Gawk is blowing up when run natively on the sparc64 -- leading to totally
