One more small cleanup, forgotten yesterday.
Reported by:	lwhsu

Remove # $FreeBSD$ from Makefiles.

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:*.

STAGIFY

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

- Get Rid MD5 support

add SHA256

- Register conflicts

Add MASTER_SITE_LOCAL to the dist list since pointhat seems to have
trouble with the main site sometimes.  The file should start appearing
on the mirrors in a day or two.
