crtc->funcs->lock is NULL, so it's no use calling it here. Move it down so
it's actually defined before we use it.

This moves code out of each implementation of set_mode_major and back into
the X server. The real feature here is that the transform is now available
in the crtc for use by either xf86CrtcRotate or whatever the driver wants to
do. Without this change, the transform was lost for drivers providing the
set_mode_major interface.
Note that users of this API will want to stop smashing the transformPresent
field, and could also stop setting mode/x/y/rotation for new enough X servers,
but there's no reason to make that change as it will break things when
running against older X servers.

dixLookupResource attempted to automatically detect whether the caller
wanted a lookup by-type or by-class, unfortunately, it guessed wrong for
RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.

You could be more clever than this, but the wire protocol says this

c859b736d1 removed duplicate entries for
these from the Makefile, but removed a different set than was done in
master branch, causing xf86Parser.h to not be installed, which in turn
breaks the build of drivers like -ati, -intel & -nv that use xf86Modes.h,
which includes xf86Parser.h

The old DRI2 buffer allocation API wasn't great, but there's no reason to
make the server stop working with those drivers. This patch has the
X server adapting to the API provided by the driver, using the new API where
available and falling back to the old API as necessary. A warning will be
placed in the log file when the old API is in use.

Wrong check for inputInfo.pointer resulted in a SW cursor being rendered when
the pointer left the screen (in a Xinerama setup).
We must call the sprite rendering function if
- SW cursors are enabled, or
- The current device is not the VCP and not attached to the VCP.

Zapping is triggered by xkb these days, so note in the man page that it's the
Terminate_Server action. Since it's XKB, personal preferences towards or
against zapping should be achieved through xkb rulesets.
If Terminate_Server is not in the xkb actions, then we can't zap anyway and we
don't need a default of DontZap "on".
This patch restores the old meaning of DontZap - disallow zapping altogether,
regardless of XKB's current keymap.
Ideally, this patch should be accompanied by b0f64bdab00db652e in
xkeyboard-config.

In ProcXkbGetKbdByName, mrep.firstVModMapKey, .nVModMapKeys and
.totalVModMapKeys were not initialized, contained random values and caused
accesses to unallocated and later modified memory, causing
XkbSizeVirtualModMap and XkbWriteVirtualModMap to see different number of
nonzero values, resulting in writes past the end of an array in XkbSendMap.
This patch initializes those values sensibly and reverts commits 5c0a2088 and
6dd4fc46, which have been plain non-sense.

This change implements the protocol for DRI2GetBuffersWithFormat, but
the bulk of the differences are the changes to the extension / driver
interface to make this function work. The old CreateBuffers and
DeleteBuffers routines are replaced with CreateBuffer and DeleteBuffer
(both singular).
This allows drivers to allocate buffers for a drawable one at a time.
As a result, 3D drivers can now allocate the (fake) front-buffer for a
window only when it is needed. Since 3D drivers only ask for the
front-buffer on demand, the real front-buffer is always created. This
allows CopyRegion impelemenations of SwapBuffers to continue working.
As with previous version of this code, if the client asks for the
front-buffer for a window, we instead give it the fake front-buffer.
