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 trailing whitespace from Makefiles, M-X.

Update Mesa port to 10.6.6 and add Clover.
Add beignet 1.1.0.
Add clinfo, clblas, clfft and clrng.

The major change is that all Mesa ports are now configured the same way.
This fixes several problems and enables new features.  The details
are described in this blog post:
http://blogs.freebsdish.org/graphics/2015/03/18/unifying-mesa-ports-configure/

The second important change is the OpenCL support.  Mesa's
implementation, Clover, is enabled as well as Beignet.  Clover
targets all Gallium drivers, only Radeon GPUs in our case.  Beignet
is for Intel GPUs starting with Ivy Bridge.  Thanks to Johannes
Dieterich, O. Hartman, and Koop Mast for their work on OpenCL!  As a
bonus, there are several OpenCL-based math ports added (clblas,
