Re-implement -l flag; diff -l now works correctly in non-directory
mode (like GNU diff).

Add -q option from GNU diff

Implement -P from GNU diff (like -N but only for files that are missing
from dir1).

Some fairly major changes:
o -N is implemented
o -X is implemented
o -x is implemented
o diff.c has been rewritten and GNU long options are now supported
o diffdir.c has been rewritten
+ no

Some fairly major changes:
o -N is implemented
o -X is implemented
o -x is implemented
o diff.c has been rewritten and GNU long options are now supported
o diffdir.c has been rewritten
+ no longer does fork + exec of /usr/bin/diff
+ can be called recursively (and will be for -r)
o diff.h
+ don't include any .h files here any more, do it in the .c files
+ no Bell Labs code in this, gets a UCB copyright (the 32v sources
only have a diff.c and there is nothing in common).
o diffreg.c
+ most all remaining globals are now private to diffreg.c
+ files are only opened once
+ dynamically allocated objects are either freed or realloced
+ added missing UCB copyright (there were lots of UCB changes)
+ print correct thing when -s is specified

Some cosmetic fixes:

o move inifdef into diffreg.c (only used there)
o correct a comment
o use _PATH_DIFF, _PATH_DIFFH and _PATH_PR instead of variables set
