glDeleteTextures and glDeleteTexturesEXT were erroneously listed as
aliases of each other. For anything /except/ GLX protocol they are
aliases. This set of changes allows functions that are functionally
identical but have different GLX protocol to be listed as aliases.
When building with GLX_INDIRECT_RENDERING set, different static
functions are used. These functions determine whether the current
context is direct rendering or not. If the context is direct
rendering, the aliased function (e.g., glDeleteTextures in the case of
glDeleteTexturesEXT) is called. If the context is not direct
rendering, the correct GLX protocol is sent.

Make 'USING_EGL=0' the default for now. It's causing too much confusion for
too many non-developers (which in turn wastes too much developer time). It
is trivially overridden from the make command line. See comments in
linux-dri.
should be defined. It was flawed on some platforms (e.g., Darwin & mingw).
Instead, rely on the build system to define it on the compiler command line.
This also reverts ajax's hand-edit to indirect_size.c. I'll fix that on the
X.org side of things later today.
linux-dri, but it disables support for direct-rendering in it. This config
mainly exists so that I can verify that changes to libGL haven't broken
builds on non-DRI platforms.
