Remove WWW entries moved into port Makefiles

Commit b7f05445c00f has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.

This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

Add WWW entries to port Makefiles

It has been common practice to have one or more URLs at the end of the
ports' pkg-descr files, one per line and prefixed with "WWW:". These
URLs should point at a project website or other relevant resources.

Access to these URLs required processing of the pkg-descr files, and
they have often become stale over time. If more than one such URL was
present in a pkg-descr file, only the first one was tarnsfered into
the port INDEX, but for many ports only the last line did contain the
port specific URL to further information.

There have been several proposals to make a project URL available as
a macro in the ports' Makefiles, over time.

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:*.

Support LIBS like LDFLAGS.

- Add LIBS="${LIBS}" to MAKE_ENV and CONFIGURE_ENV.
- Add an option helper for LIBS.
- Adjust all ports that already use LIBS.  Also remove references to
  PTHREAD_CFLAGS and PTHREAD_LIBS while here.
- Some ports did not support having a LIBS environment variable and
  required additional patches.

Somewhat simplified a linker command line looks like:

${CC} ${src_LDFLAGS} ${LDFLAGS} ${src_LIBS} ${LIBS}

where src_LDFLAGS and src_LIBS are controlled by upstream and LDFLAGS and
LIBS can be controlled by us.  If possible -L and -l flags need to be

Support staging

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

- Reassign to the heap

- Add LDFLAGS to CONFIGURE_ENV and MAKE_ENV (as it was done with LDFLAGS)
- Fix all ports that add {CPP,LD}FLAGS to *_ENV to modify flags instead
