Add various GLX extensions to the list of supported extensions.
Reformat the oddly formatted code in some areas.
Use xalloc and xfree instead of malloc and free.
Add some commentary about future directions needed for the GLX drawable
creation and destruction code.
Match xalloc with xfree.
I made some minor formatting improvements.
In attach() check for pDraw being NULL, and also print an ErrorF message,
because we eventually want to track down why this is occuring.
It's unclear how this occurs, but as I noted in the 1.4 branch, I believe that
the DrawablePtr/struct _Drawable -> id is the member being accessed that causes
KERN_PROTECTION_FAILURE at 0x0000000000000004
This passes my tests using: env LIBGL_ALWAYS_INDIRECT=1 ./sometest.
I fixed a warning: caused by initializing the screen->base.visuals with the
configs. It is a ** not a *. It seems that some other part of GLX will
initialize this for us.
It looks much better with the new GLX/libGL, perhaps because of the old libGL
not understanding all of the tags written. At least glxgears works with both.
glxgears is not a test for all OpenGL features, so most likely some things
are broken still. Direct rendering is known to not work, or at least being
reported as not working.
Fix some obvious errors with uninitialized new members of GLX structs.
Add a type argument for the screen's drawable creation function, and pass the type to
__glXDrawableInit().
GLX still doesn't work. There is more work needed to get it working again. This gets
it building at least, although there are some warnings in the dispatch table setup,
that seem to be caused by const differences.
I also #if 0ed a bunch of function bodies that will need to be revisited soon.
Added a configure option called --enable-standalone-xpbproxy which is useful for deveoping xpbproxy.
The 'active' switch in preferences just disables the in-server xpbproxy (not this standalone).

This prevents visuals with odd sizes. The machine I use didn't have
this problem, but it shows up on some others.
(cherry picked from commit ed181382dd)
Use the settings queried from the system in xprScreen.c, rather than those 2 calls.
The 2 calls increased the total number of visuals a great deal (when using GLXEXT),
and not all of the visuals were usable with GLX. Some of the visuals aren't usable
with GLX still, such as DirectColor, but that seems to be acceptable based on my
understanding of the manual that states "a subset of visuals are made available
for OpenGL rendering."
