Restructure the error handling portion of the resource allocation
code to eliminate duplicated code.
Test for the O_NONBLOCK && fi_readers == 0 case before incrementing
fi_writers and modifying the the socket flag to avoid having to
undo these operations in this error case.
Restructure and simplify the code that handles blocking opens.
There should be no change to functionality.

expense of warnings about bad RID allocations. I'm not sure this is a
permanant workaround, but does appear to help in the tests that I've
done here.

incorrectly spelt ``Random Early Detection'' as ``Random Early Drop''.
While I am there, nuke IF_ENQ_DROP from the list of functions. More
work will be done on this, since some of the functions like
if_enq_drop() and if_queue_drop() were replaced with one function
called if_handoff() that does the job of enqueing the packet and
updating interface statistics as necessary.

This allows one to tag code in the tree that will be deleted in 6.x
with the 'OBSOLETE_IN_6 #define at the top of the file. This makes
for easy grepping, plus a mechanism that automatically fails the
compilation of those files that are so tagged after we do the cutover.

o Safe the INTR_MPSAFE flag for client drivers (don't know if there are any
CardBus/PCI drivers that are INTR_MPSAFE)
o Read status after acquiring mtx_lock(Giant) rather than before so that we
catch state changes that happen while Giant is being acquired.
o Turn off the CD bit when we see a CD interrupt, and turn it back on after

o On suspend, actually set the CBB_SOCKET_MASK to zero rather than oring

o If the ISR that's registerd is MPSAFE, don't acquire Giant around call to

o Fix comments to reflect these changes.
