2011-01-22scons: Add support for GLES.Chia-I Wu
GLES can be enabled by running scons with $ scons gles=yes When gles=yes is given, the build is changed in three ways. First, libmesa.a will be built with FEATURE_ES1 and FEATURE_ES2. This makes DRI drivers and libEGL support and advertise GLES support. Second, GLES libraries will be created. They are libGLESv1_CM, libGLESv2, and libglapi. Last, libGL or opengl32 will link to libglapi. This change is required as _glapi_* will be declared as __declspec(dllimport) in libmesa.a on windows. libmesa.a expects those symbols to be defined in another DLL. Due to this change to GL, GLES support is marked experimental. Note that GLES requires libxml2-python to generate some of its sources.
2011-01-20glapi: Fix OpenGL and OpenGL ES interop.Chia-I Wu
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.

2011-01-20glapi: Fix OpenGL ES 1.1 and 2.0 interop.Chia-I Wu
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.
