filesystems: add new category for file systems and related utilities

The filesystems category houses file systems and file system utilities.
It is added mainly to turn the sysutils/fusefs-* pseudo-category into
a proper one, but is also useful for the sundry of other file systems
related ports found in the tree.

Ports that seem like they belong there are moved to the new category.
Two ports, sysutils/fusefs-funionfs and sysutils/fusefs-fusepak are
not moved as they currently don't fetch and don't have TIMESTAMP set
in their distinfo, but that is required to be able to push a rename
of the port by the pre-receive hook.

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories s

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

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

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:*.

Rename sysutils/ patch-xy patches to reflect the files they modify.

Support STAGEDIR.

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

Convert to USES=imake
Trim headers

- Get Rid 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.

Fix USE_XORG in preparation of ports/122340. Since USE_IMAKE is bringing in
all xorg-libraries, there's no need to bump PORTREVISION for now.

- Welcome X.org 7.2 \o/.
- Set X11BASE to ${LOCALBASE} for recent ${OSVERSION}.
