Make fetchable again. The distfile was rerolled years ago.

The difference between the old and the new distfiles are a lot of CVS
ids in comments, and the config.in.h being regenerated with a newer
version of autoheader. (Which we do not care about here because we use
autoreconf anyway.)  While there, also put up a copy in
MASTER_SITE_LOCAL.

- Remove expiration, I'll fix it up as best as I can if it breaks.
- General cleanup of the Makefile
- Fix of a manpage symlink (reason for PORTREVISION bump)
- Document what the patches are for. (and regen when needed.)
