Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories p

Add USES=xorg and USES=gl to ports in categories starting with 'p'
While here, try to sprinkle other USES (mostly gnome and sdl) as needed.

Cleanup $() variables in ports Makefiles.

Mostly replace with ${}, but sometime, replace with $$() because it is
what was intended in the first place. (I think.)

- Fix trailing whitespace in pkg-descrs, categories [p-x]*

Approved by:	portmgr blanket

MASTER_SITES cleanup.

- Replace ${MASTER_SITE_FOO} with FOO.
- Merge MASTER_SITE_SUBDIR into MASTER_SITES when possible. (This means 99.9%
  of the time.)
- Remove occurrences of MASTER_SITE_LOCAL when no subdirectory was present and
  no hint of what it should be was present.
- Fix some logic.
- And generally, make things more simple and easy to understand.

While there, add magic values to the FESTIVAL, GENTOO, GIMP, GNUPG, QT and
SAMBA macros.

Also, replace some EXTRACT_SUFX occurences with USES=tar:*.

Support stage

Add NO_STAGE all over the place in preparation for the staging support (cat:

- Kick MD5 Support

For ports maintained by ports@FreeBSD.org, remove names and/or
e-mail addresses from the pkg-descr file that could reasonably
be mistaken for maintainer contact information in order to avoid
confusion on the part of users looking for support. As a pleasant
side effect this also avoids confusion and/or frustration for people
who are no longer maintaining those ports.

Reset maintainer, address bounces:

installed anymore.
