some optional, you probably don't need these patches for post.c

[Aaron Nabil <nabil@teleport.com>]

I'm trying to trace down the source of my "memory corrupt"'s from mmaloc,
and I noticed that most of them were after a post.  So I was polking around
post.c, and altough I didn't find anything wrong, did fix a few minor
nits.  There also a local "feature" you might find useful.

If the post_cfg linked list was getting free'd someplace, I couldn't find
it.  I wrote a little sub to do it, and called it in the appropriate place.

There is some added code that will prevent certain header from being
supplied by the user.  This is strictly a local preference, set it
as you require.  Surpressing things like "Path:" is to be done with care.

If no newsgroups were in the message, the message wasn't getting free'd
before exiting.

These (except for the header supression) aren't well tested, you might
just stuff them away for future use.
