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.

Approved by:		portmgr (tcberner)

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.

graphics/libglvnd: fix on armv6/armv7

The .thumb_func directive does not switch to thumb mode in clang's
integrated assembler.  This causes the code to be miscompiled in that
it is generated as ARM code but the symbols are tagged as thumb.  The
resulting library is unusable.  Every call into it crashes.

Fix this issue by applying an upstream patch set to have the entry
stubs be in ARM mode instead of Thumb mode.

Regenerate all distfiles using gitlab as source.

This regeneration is required as the new gitlab version changed
the address and the directory the source files can be downloaded.

This commit also applies some small fixes to make sure all ports using
gitlab are buildable.

graphics/libglvnd: add new port

Submitted by:	Greg V <greg@unrelenting.technology>

libglvnd is a vendor-neutral dispatch layer for arbitrating OpenGL API calls
between multiple vendors. It allows multiple drivers from different vendors to
coexist on the same filesystem, and determines which vendor to dispatch each
API call to at runtime.

Both GLX and EGL are supported, in any combination with OpenGL and OpenGL ES.
