resolve merge conflicts and update for proper build; including:

o print-fr.c returned to code on vendor branch
o remove pmap_prot.h include from print-sunrprc.c
o remove gcc/i386-specific ntoh* write-arounds from tcpdump-stdinc.h

Merge of tcpdump 3.8.3 from tcpdump.org, with the following caveats:

print-atm.c no longer performs special handling for FORE headers; these
can no doubt be re-added at a later date.

print-fr.c is effectively a no-op.

print-llc.c has had the default_print_unaligned() call removed as
tcpdump no longer defines this function, however the prototype is still
present. Suggest we roll in a diff to use print_unknown_data().

Merge tcpdump 3.3.
The print_nfs.c changes are pretty extensive; this is partially because
LBL did a lot of cleanup and partially because I removed lots of
pointless changes away from the LBL style.
