Allow the location of the SERVERCONFIGdir variable to be defined at
compile-time. This allows us to specify where the security policy will be
located (Debian uses this to put it in /etc). The default is to the
previous location.
Major stylistic cleanups, greatly expanded cross-reference ("SEE ALSO")
section and some typo fixes.

When the root window changed size, xf86XVFillKeyHelper would not revalidate
the GC, leaving the clip at the old size causing lossage (and possibly
memory corruption if the screen and frame buffer shrank).
Fixed by just using a scratch GC; saving memory, eliminating bugs and
shrinking the code.
When available, use the 2D driver texOffsetStart hook and the 3D driver
setTexOffset hook to save the overhead of passing the pixmap data to
glTex(Sub)Image.
The basic idea is to update the driver specific 'offset' for bound pixmaps
before dispatching a GLX render request and to flush immediately afterwards
if there are any pixmaps bound. This should ensure that the 3D driver can
use pixmaps for texturing directly regardless of the X server moving them
around.
To be used by AIGLX for GLX_EXT_texture_from_pixmap without several data copies.
The texOffsetStart hook must make sure that the given pixmap is accessible by
the GPU for texturing and return an 'offset' that can be used by the 3D
driver for that purpose.
The texOffsetFinish hook is called when the pixmap is no longer being used for
texturing.
This counter exposes the time in milliseconds since the last
input event. Clients such as screen savers and power managers
can set an alarm on this counter to find out when the idle time
reaches a certain value, without having to poll the server.
DRI uses a non-screen block/wakeup handler which will be executed after the
screen block handler finishes. To ensure that the rotation block handler is
executed under the DRI lock, dynamically wrap the screen block handler for
rotation.
Leaving devices enabled during server startup can cause problems during the
initial mode setting in the server, especially when they are used for
different purposes by the X server than by the BIOS. Disabling all of them
before any mode setting is attempted provides a stable base upon which the
remaining mode setting operations can be built.
The code in hw/xfree86/os-support/bus/sparcPci.c:simbaCheckBus()
is trying to mimmick VGA routing by disabling I/O space responses
behind the Simba PCI-PCI controller.
Unfortunately, doing this also happens to disable access to the
IDE controller I/O space registers, thus crashing the system. The
granularity of the I/O disabling in the Simba controller is not
fine enough to disable VGA without also disabling the IDE controller
registers.
