We need more and more of these, and it is difficult and prone to version
incompatability issues trying to single out every one of them.
This mimicks what was done in SCons.
This an adds --enable-shared-dricore option to configure. When enabled,
DRI modules will link against a shared copy of the common mesa routines
rather than statically linking these.
This saves about 30MB on disc with a full complement of classic DRI
drivers.
v2: Only enable with a gcc-compatible compiler that handles rpath
Handle DRI_CFLAGS without filter-out magic
Build shared libraries with the full mklib voodoo
Fix typos
v3: Resolve conflicts with talloc removal patches

When --enable-shared-glapi is specified, libGL will share libglapi with
OpenGL ES instead of defining its own copy of glapi. This makes sure an
app will get only one copy of glapi in its address space.
The new option is disabled by default. When enabled, libGL and libglapi
must be built from the same source tree and distributed together. This
requirement comes from the fact that the dispatch offsets used by these
libraries are re-assigned whenever GLAPI XMLs are changed.
For GLX, indirect rendering for has_different_protocol() functions is
tricky. A has_different_protocol() function is assigned only one
dispatch offset, yet each entry point needs a different protocol opcode.
It cannot be supported by the shared glapi. The fix to this is to make
glXGetProcAddress handle such functions specially before calling
_glapi_get_proc_address.
Note that these files are automatically generated/re-generated
src/glx/indirect.c
src/glx/indirect.h
src/mapi/glapi/glapi_mapi_tmp.h
Move _glapi_* symbols from libGLESv1_CM.so and libGLESv2.so to
libglapi.so. This makes sure an app will get only one copy of glapi in
its address space.
Note that with this change, libGLES* and libglapi must be built from the
same source tree and distributed together. This requirement comes from
the fact that the dispatch offsets used by these libraries are
re-assigned whenever GLAPI XMLs are changed.
With core mesa doing runtime API checks, GLES overlay is no longer
needed. Make --enable-gles-overlay equivalent to --enable-gles[12].
There may still be places where compile-time checks are done. They
could be fixed case by case.
If you want to enable noop set GALLIUM_NOOP=1 as an env variable.
You need first to enable noop wrapping for your driver see change
to src/gallium/targets/dri-r600/ in this commit as an example.

Use --cppflags instead of --cflags so that we get the -I and -D flags
we want, but not compiler options like -O3.
A similar change should probably be made for autoconf.
First, it changes autoconf to use a "python2" binary when available,
rather than plain "python" (which is ambiguous). Secondly, it changes
the Makefiles to use $(PYTHON) $(PYTHON_FLAGS) rather than calling
python directly.

Code in glx/glxcmds.c which uses the XF86VIDMODE extension is already guarded. Also use
that guard to control inclusion of the xf86vmode.h header, and only enable that guard if the
XF86VIDMODE extension is found by pkgconfig.
This changes the behaviour on platforms which XF86VIDMODE exists, in that XF86VIDMODE used to
be mandatory, but is now optional.
Presumably other build systems are already arranging for -DXF86VIDMODE to be supplied to the
complier when glxcmds.c is compiled, so are not affected by this change

I had used pkg-config from the Makefile because I didn't want to screw
around with the non-autoconf build, but that doesn't work because the
PKG_CONFIG_PATH or TALLOC_LIBS/TALLOC_CFLAGS that people set at
configure time needs to be respected and may not be present at build
time.
Bug #29585
Fix this build error (in MesaGLUT-7.6.1)...
glut_cmap.c:23:66: error: X11/Xmu/StdCmap.h: No such file or directory
...by not preventing the cflags that pkg-config finds for glut dependencies
(including 'xmu') from being used.
Defining GLUT_CFLAGS before running the pkg-config prevents the
cflags found by pkg-config from being used.
This patch lets GLUT_CFLAGS that configure & pkg-config work
so hard to set actually get used.
Also make sure the generated configs/autoconf defines GLUT_CFLAGS
used in (at least) src/glut/glx/Makefile.

With the omit list gone, there are not too many differences in building
core mesa and ES overlay. Remove the mesa/es and build both of them in
src/mesa/Makefile.
The new target installs client API modules to EGL_DRIVER_INSTALL_DIR.
They are used by st/egl.
The client APIs are built from OpenGL and OpenVG state trackers. For
this to work, st/vega is modified to produce a static library,
libvega.a, instead. st/es is also not needed any more. It is removed
and --with-state-trackers=es is replaced by --enable-gles-overlay.
As st/egl now has its own client API modules, this solves the ABI issue
between st/egl and client APIs, as long as the client API modules are
distributed with st/egl. Plus, this allows st/egl to support OpenGL
with non-Gallium libGL.so.
Define <API>_LIB, <API>_LIB_NAME, <API>_LIB_GLOB, and some other
variables in the configs. Fix a typo in glesv1_cm.pc.in where an
inexistent variable is used.
ES overlay is built with FEATURE_ES1 or FEATURE_ES2, and is built
without FEATURE_GL. Fix the build by always building OpenGL ES sources,
but test for FEATURE_ES1 or FEATURE_ES2. Also, define symbols that are
missing because FEATURE_GL is not defined.
