(I skipped those in contrib/, gnu/ and crypto/)
While I was at it, fixed a lot more found by ispell that I
could identify with certainty to be errors. All of these
were in comments or text, not in actual code.

plain 0 should be used. This happens to work because we #define
NULL to 0, but is stylistically wrong and can cause problems
for people trying to port bits of code to other environments.

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- Fix typos in comments in hash.c.
- Remove unneeded and unused member from grouplist struct in hash.h.
(Curiously, the compiler never complained about this even though the
member was of type 'struct grps' which is not defined anywhere in
this program.)
- char ch -> int ch in revnetgroup.c.
- char *argv[0]; -> char *argv[]; also in revnetgroup.c.
- Force the user to specify at least one of the -u or -h flags
and complain if they specify both.
program parses the /etc/netgroup file into netgroup.byuser and netgroup.byhost
format for NIS.
I used hash tables to store the initial netgroup data in memory and to
construct the 'reverse' netgroup output. It seems just as fast as the
SunOS revnetgroup, which is surprising considering this is my first
attempt at using hash tables in a real application. :)
Note that I canibalized a large chunk of getnetgrent.c to save myself
from having to write my own netgroup parsing functions.
