As proposed by Owen Taylor [1], the enter-leave event model needs to adjust
the events sent to each window depending on the presence of pointers in a
window, or in a subwindow.
The new model can be summarised as:
- if the pointer moves into or out of a window that has a pointer in a child
window, the events are modified to appear as if the pointer was moved out of
or into this child window.
- if the pointer moves into or out of a window that has a pointer in a parent
window, the events are modified to appear as if the pointer was moved out of
or into this parent window.
Note that this model requires CoreEnterLeaveEvent and DeviceEnterLeaveEvent to
be split and treated separately.

FirstPointerChild: Return the first child that has a pointer within its
boundaries.
FirstPointerAncestor: return the first ancestor with a child within its
boundaries.
These are required for the updated enter/leave model.

Device events always need to be delivered, core events only in some cases.
Let's keep them completely separate so we can adjust core event delivery.

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.

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.

Previously each server starting ran xkbcomp with the output set to
<keymapname>.xkm, read it, then deleted it - which led to races if
two servers were starting at the same time with the same keymap.
Sun bug #6773816 Xorg uses the same xkm output file for compiled keymap file
<http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6773816>
This way we on't need to hold the mutex during the dixSaveScreens() call.
