Remove the "If only executable code is distributed..." paragraph from
the license text. Everything now uses a normal MIT license.
The only code from Khronos that's included in libglvnd is the EGL/GL
header and XML files, which do not contain that paragraph.

Theres a couple of things that this meson build system does differently
than autotools. It doesn't use a config.h file, it just puts #defines on
the command line with -D. It also does all of the code generation in the
generated folder, simply because it's simpler to do that.
On my 2 core / 4 thread KBL system:
autotools (no ccache):
sh -c "./autogen.sh&& ./configure && make -j6 check" 44.74s user 6.70s system 145% cpu 35.269 total
autotools (warm ccache):
sh -c "./autogen.sh&& ./configure && make -j6 check" 32.86s user 4.22s system 129% cpu 28.580 total
meson (no ccache):
sh -c "meson build; ninja -C build test" 23.48s user 3.71s system 236% cpu 11.487 total
meson (warm ccache)
sh -c "meson build; ninja -C build test" 16.06s user 2.31s system 210% cpu 8.727 total
These use the symbol-check.py script from mesa, and should help to
ensure that glvnd doesn't start exposing/hiding new symbols. It's also
useful to double check that meson and autotools are doing the same
thing.
This preserves the names from Mesa's gl, glesv1_cm, glesv2, and egl pkgconfig
data, and for compatibility with that, gl.pc gives you libGL.
Also added glx.pc and opengl.pc for libglvnd's libGLX and libOpenGL libraries.
If newer applications want to explicitly depend on libGLX and the appropriate
rendering API they can ask for the new pkgconfig names.
Note that the version numbers in each file are the API versions that each
library exposes, not the libglvnd package version.
Generating a symbol list for the entrypoint libraries used to be necessary when
we generated the same set of dispatch stubs in each library.
Since then, we only generate the stubs that each library is going to export, so
we don't need a separate export list anymore.
If libglvnd is installed onto a system that already has non-libglvnd versions
of any of the OpenGL libraries installed, then ldconfig can get confused about
which files to create symlinks to. At worst, you could end up with a mix of the
libglvnd libraries and leftover non-libglvnd libraries.
To avoid that, bump the version numbers in these filenames:
- libGL.so.1.0.0 -> libGL.so.1.7.0
- libGLESv1_CM.so.1.0.0 -> libGLESv1_CM.so.1.2.0
- libGLESv2.so.2.0.0 -> libGLESv2.so.2.1.0
- libEGL.so.1.0.0 -> libEGL.so.1.1.0

Move the various vnd-glapi builds into individual .la files in the vnd-glapi
makefile, instead of defining them in the OpenGL, GL, GLESv1, and GLESv2
makefiles.
Fixed a few order and variable name warnings.
Defined convenience libraries for the source files under src/util, to avoid the
subdir-objects warning from them.
Added a Makefile to build libGLESv1_CM.so. It's copied and adapted from the one
for libOpenGL.so.
The GLESv1 library currently exports all of the core functions in gl.xml for
GLES version 1.0.
