At this point, GL_EXT_stencil_two_side should probably be disabled.
It may be worth leaving it enabled because it has GLX protocol while
GL_ATI_separate_stencil does not. I'll leave it to one of the r300
maintainers to make the call.
Track separate back-face stencil state for OpenGL 2.0 /
GL_ATI_separate_stencil and GL_EXT_stencil_two_side. This allows all
three to be enabled in a driver. One set of state is set via the 2.0
or ATI functions and is used when STENCIL_TEST_TWO_SIDE_EXT is
disabled. The other is set by StencilFunc and StencilOp when the
active stencil face is set to BACK. The GL_EXT_stencil_two_side spec has
more details.

GLEW does some defining/undefining of GLAPIENTRY making it unreliable. GLEW
should also be fixed, but removing the dependency on this symbol.
This also restores the ability for GLUT to be used with -fvisibility=hidden.
The downside of this is that ld warns of:
Warning: size of symbol `glutBitmapXXXXX' changed from 4 in glut_xxx.o to 16 in glut_xxxx.o
Due to the fonts being declared void * (*4 bytes), but defined as 16byte static
structure. I'll fix that in a later commit.

We only allow combined depth+stencil renderbuffers so the complicated code
for splitting and combining separate depth and stencil buffers is no longer
needed.
Take advantage of the GL_FRAMEBUFFER_UNSUPPORTED feature to disallow separate
depth and stencil renderbuffers; only allow combined depth/stencil buffers.
Next up: remove/simplify a bunch of the depth/stencil renderbuffer code.
Also: restore the previously disabled GL_DEPTH_COMPONENT16 case
Try making depth/stencil attachments in two different ways.
Check for GL errors and GL_FRAMEBUFFER_UNSUPPORTED status to be more robust.
Reorganize the code a bit to make it clearer.
Added -arb option to test GL_ARB_fbo's mixed renderbuffer sizes
Added -ds2 option to test GL_DEPTH_STENCIL_ATTACHMENT
When we change a FBO's attachments, set _Status=0.
Before using an FBO, check if status != GL_FRAMEBUFFER_COMPLETE.
Also, fix missing GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE status.
Called from the _mesa_test_framebuffer_completeness() function to give the
driver the chance to make a framebuffer as incomplete if it doesn't meet
some specific hardware restriction.
