Composite's automatic redirection is a more general mechanism than the
ad-hoc BS machinery, so it's much prettier to implement the one in terms
of the other. Composite now wraps ChangeWindowAttributes and activates
automatic redirection for windows with backing store requested. The old
backing store infrastructure is completely gutted: ABI-visible structures
retain the function pointers, but they never get called, and all the
open-coded conditionals throughout the DIX layer to implement BS are gone.
Note that this is still not a strictly complete implementation of backing
store, since Composite will throw the bits away on unmap and therefore
WhenMapped and Always hints are equivalent.
Before putting anything on the screen, check if the GC was made for the
ScreenRec we want to render to. If not, toss the GC and create a new one. This
is not the best solution but it does the job for now. Same thing for ARGB
cursors except that it's even uglier.
Also remember the screen the cursor was rendered to and check for the right
screen in the BlockHandler, SourceValidate and a few others. Only remove or
restore the cursor if we are rendering to the same screen, otherwise we get
artefacts that are both funky and really annoying.
Improve memory usage by allocating the sprite's memory only to devices that
actually have a sprite and provide means to remove a device's cursor from the
screen (more hotplugging, yay!).
This commit breaks ScreenRec's ABI.

misprite.c passes DeviceIntPtr around and down to DC (previously
miCursorInfoPtr and the plain device id).
Large cleanup in misprite.c to avoid code duplication.
added id field to miCursorInfoPtr, required to pass through to miDC
core pointer uses mpCursors array as well.
added miDCBufferRec for future use with MPX

Add XSERV_t, TRANS_SERVER, TRANS_REOPEN to quash warnings.
Add #include <dix-config.h> or <xorg-config.h>, as appropriate, to all
source files in the xserver/xorg tree, predicated on defines of
HAVE_{DIX,XORG}_CONFIG_H. Change all Xfont includes to
<X11/fonts/foo.h>.
change "foo.h" to <X11/foo.h> for core headers, e.g. X.h, Xpoll.h;
change "foo.h", "extensions/foo.h" and "X11/foo.h" to
<X11/extensions/foo.h> for extension headers, e.g. Xv.h;
change "foo.[ch]" to <X11/Xtrans/foo.[ch]> for Xtrans files.
