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.

When the linux kernel sets the NX bit vm86 segfaults when it tries to execute
code in memory that is not marked EXEC. Such code gets called whenever
we return from a VBIOS call to signal the calling program that the call
is actually finished and that we are not trapping for other reasons (like
IO accesses).
Use mprotect(2) to set these memory ranges PROT_EXEC.
There's little chance that we'll get the input devices at runtime without HAL,
we might as well force the server to add mouse/kbd devices automatically -
just like in the olden days.

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."

It was returning inverted values in comparison to the 1.4 branch. This resulted in
the windows not drawing due to a deep path of: RootlessReorderWindow ->
SCREENREC(pScreen)->imp->DoReorderWindow(winRec) - > xprDoReorderWindow ->
AppleWMDoReorderWindow.

As reported in http://bugs.freedesktop.org/show_bug.cgi?id=18438
the server suggests reconfiguring HAL if AllowEmptyInput is enabled
and no input devices are known.
Instead of that notice, if HAL is disabled at configure time,
AllowEmptyInput is enabled in the config and no input devices are
found report those facts and recommend disabling AllowEmptyInput.
When using any XAAPixmapOps, we call into unknown but freshly
unwrapped callbacks (like fb ones). Unlike the XAA*Fallback calls,
we did so without syncing first, exposing us to all kinds of
synchronisation issues.
I believe that the rendering errors appeared now because *PaintWindow
vanished (e4d11e58), and we just use miPaintWindow instead. This
takes a less direct route to the hw and ends up at
PolyFillRectPixmap, which very often left drawing artifacts.
We now sync accordingly, and no longer get the rendering artifacts i
was methodically reproducing on radeonhd, radeon, unichrome...
Also, in order to allow driver authors to remove extensive syncing
or flushing to hide this issue, create XAA_VERSION_ defines, put
them in xaa.h and bump the patchlevel.
(novell bug #435791)
When setting the depth to 24, leave bpp unset so the logic to pick
a supported value is used instead of ignoring the driver's preference
and forcing 32 bpp.
