small but noticeable increase in performance for name lookup operations.
The code uses two zones, one for short names (less than 32 characters)
and one for long names (up to NAME_MAX). Since most file names are
fairly short, this saves a considerable amount of space that would
otherwise be wasted if we always allocated NAME_MAX bytes. The cutoff
value of 32 characters was picked arbitrarily and may benefit from some
tweaking; it could also be made into a tunable.

These have been marked as being deprecated in their manual pages since 5.0,
and their use causes a linker warning.
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.

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.

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.
