Consolidate the Mesa ports, update to 17.0.4, and add Wayland option

* libGL, libEGL, libglesv2, libglapi, and gbm have been moved into mesa-libs,
  graphics/dri has been renamed to mesa-dri, and USE_GL has been adjusted
* mesa-libs has a new WAYLAND option that enables platform support in libEGL
* mesa-dri now depends on graphics/s2tc for compressed texture support [1]
* re-remove obsolete dependency on makedepends [2]
* correct sed fix backported from 17.1 [3]

Update to 13.0.5

Approved by:	swills (mentor)
Differential Revision:	https://reviews.freebsd.org/D9781

Now that all supported FreeBSD versions support libmap.conf files installed
from ports, remove the symlink dance with libGL/libEGL/libgles and the
nvidia-driver ports.

* Revert libGL/libEGL/libglesv2 ports to normal.
* Rename the conflicting libraries from the nvidia-driver ports with a
  -NVIDIA prefix and install a libmap.conf file to map to these versions.
* Remove the special case from Mk/Scripts/qa.sh for libGL and libEGL.
* Sadly the symlink dance between nvidia-driver and xorg-server for glx.so
  need to stay, due to xorg-server opening that file with dlopen(3).

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,

Update to 10.3.4.

Enable TEXTURE option in dri by default [1]. This allows for OpenGL higher
  then 2.1 to be supported.
Make sure we depend on llvm at run time when gallium is enabled.
  The gallium based modules link to the llvm shared libraries. [2]

Fix libEGL and libGLESv2 conflict between libEGL/libglesv2 and the
nvidia-driver port in the same fashion it was done as the conflict
with the libGL port.

Mesa ports:
Add pkg-[de]install scripts to handle the symlinks in the libEGL
  and libglesv2 port.
Move pkg-[de]install scripts of libGL out of files/
Put the real mesa libraries into lib/.mesa so we don't have each
  port create a directory for it own use.

Nvidia-driver:
Only apply the libEGL.so and libGLESv2.so alternative install
  directory if nvidia-driver actually ships them. Copied from
  PR submitter, since it was much cleaner then my initial attempt.

Update Mesa ports to new default of 9.1.7 and more recent version to 10.3.0.

The port will switch to the newer version if hw context is available in the
i915kms driver.

- Get ride of WITH_NEW_XORG.
- Use @comment in plist to ignore unwanted files in the stagedir, instead of
  trying to remove them in post-install.
- Bump portrevision of 9.1.7 due to dependency changes.
- Drop :keepla from USES=libtool.
- Drop @dirrm[try] from plists
- Give dri propper options, with pkg-help for additional information.
- Make separate plist for dri for the different versions, the combined plist
  was headache inducing.
- Add "workaround" patches to allow clang to build the dri port on i386 [1].
  USE_GCC is now only needed for 8.x.
- Add gbm port and USE_GL switch for it.

Enable shared libglapi library and make a port for it. It is used by libGL
 and libglesv2. This fixes undefined symbol issues in libglesv2.
Clean up stagedir of unwanted files/directories, so check-plist passes.
Switch logic and always build gallium support in graphics/dri on i386 and
 amd64. Gallium is used for Radeon HD 5000+ support.

Use USES=tar:bzip2
Under WITH_NEW_XORG:
Add patch to remove some dependencies for aclocal.m4 which are absent.
 This allows the removal of USE_AUTOTOOLS, REAPPLY_PATCHES and pre-configure
 target.
Add INSTALL_TARGET=install-strip to strip libraries.
USES=libtool:keepla
Fix a /use typo with /usr in post-patch.

Bump PORTREVISION for the libtool and libglapi changes.

NEW XORG ON FREEBSD 9-STABLE AND 10-STABLE

This update switches over to use the new xorg stack by default on FreeBSD 9
and 10 stable, on osversions where vt(9) is available.
It is still possible to use the old stack by specifying WITHOUT_NEW_XORG in
/etc/make.conf .
FreeBSD 8-STABLE and released versions of FreeBSD still use
the old version.
A package repository with binary packages for new xorg will
be available soon.

This patch also contains updates of libxcb and related ports, pixman, as well

Update to 9.1.7.

Stagify, abuse stage dir and plist to only install files we want to install.
So we don't have to do complex do-install anymore, yay.

For the WITH_GALLIUM option we don't need llvm at run-time.
