This width/height value lets filter users know how far the filter spreads
into the source image.

Report transformed crtc sizes through RandR and Xinerama. Test screen size
against transformed mode sizes when configuring the Crtc.

Create new RRTransform datatype to hold all of the transform related
information, use that in lots of places to pass filters around.

To prepare for RandR using filters in transforms, split out
code paths so that the RandR code can validate the filter name and
parameters during the transform set operation so that use of the filter
later will not have unreportable errors.

This involved removing a pile of matrix code from the DDX,
as well as moving a bit of transform logic from DDX to DIX.

The render extension uses many matrix operations internally, this change
exposes those functions to other parts of the server, drivers and
extensions. The change is motivated by the 'transform' additions to the
RandR extension but will likely be useful elsewhere.

New RRCrtcGetTransform function in DIX that DDX can use to get the pending
transform. The DDX code should be complete; the DIX code is just a stub at
this point.

Drivers that care about crtc positions on the screen to ensure that vblank
works correctly need to be notified when crtcs are changed.

Provide a hook in the mode setting code that is invoked whenever any
configuration is done to the screen.

Use this new hook in the DRI code so that DRI clients are notified and
receive updated information.

The xfree86 server previously hat NewInputDeviceRequest and InitInput, and
both basically did the same thing. Reduce NIDR to parameter checking and use
xf86NewInputDevice from both InitInput and NIDR to actually create the device.

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.
(cherry picked from commit b772d64f)

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.

This has been replaced by in-kernel support for USB mices several
years ago and hasn't been enabled in build since X.Org 6.8.

The new replacement is __GLXconfig.

(cherry picked from commit 799715b8)

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.

Without this, commit ace38faf is useless
when HAL support is disabled.
