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.

x11: remove 'Created by' lines

Remove # $FreeBSD$ from Makefiles.

Add USES=xorg USES=gl, ports categories x

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

Apparently, Google is not only archiving the distfiles, but projects'
landing pages as well, thus redirect WWW: lines in pkg-descr to them.

- Unbreak by pointing to archived distfile in Google Cloud Storage
- Remove WWW: line from the port description for the time being

Mark the remaining ports depending on Google Code as DEPRECATED, with an
EXPIRATION_DATE at the end of April 2017.

In the past six months, about a third of the ports marked BROKEN because
they were hosted on Google Code have been fixed.  The remaining must not
be of use to anyone.

GOOGLE_CODE has gone away.

- If a port has another upstream, remove GOOGLE_CODE
- If a port only has GOOGLE_CODE mark it BROKEN

Some ports have a local mirror configured but for security reasons, it
is not considered upstream.

- Unbreak the build on -CURRENT by explicitly linking against libm as a
  remedy to the following error:

    [100%] Linking C executable bmpanel2
    /usr/bin/ld: undefined reference to symbol `truncf@@FBSD_1.0' (try
    adding -lm)
    //lib/libm.so.5: could not read symbols: Bad value

- While here fix long standing issue of -L${LOCALBASE}/lib being required
  in LDFLAGS while USES=pkgconfig due to missing LINK_DIRECTORIES() call
  in the top-level `CMakeLists.txt'

Reclaim maintainership of ports that I still use regularly, but decided to
relinquish at some point to allow contributions coming more easily (not to
impose hard lock).  These days, there is no reason to yield maintainership
with the more lax rules and general consensus that casual changes do not
necessarily require explicit approval from maintainer prior to commit.

On the other hand, unmaintained ports can give (arguably false) impression
of being unwanted and one step above deprecation, yet these ports are not.

- Simplify MASTER_SITES
- Add LICENSE_FILE
- Strip binary

Cleanup plist

- Add an optional patch to allow setting panel opacity in theme config file
- Update port description to mention features brought by unofficial patches
- Fix spelling of NETWM -> NetWM and utilize options helpers while I'm here

Stage support

Add NO_STAGE all over the place in preparation for the staging support (cat:
x11)

Add an explicit dependency on pkgconf

- convert USE_CMAKE to USES
- while here clean up some ports from CMAKE_VERBOSE, which is intended
  for users

Approved by:	portmgr (miwi)

Convert the patch into PATCHFILES: ports tree is not the best place for
storing code.

Update to the latest code on github.

Some minor cosmetic changes to the unofficial patch.

- Implement nice little temperature widget (read via sysctl(3) API)
- Trim Makefile header and slightly touch COMMENT while I am here

- Adjust COMMENT and port descriptions where appropriate
- Relinquish to the pool due severe to lack of time :-(

Add bmpanel2, a nice lightweight NETWM compliant panel for X11.
