Previously the code was using AC_CHECK_LIB, guaranteeing whether the library
is correct by tracking sha1_begin function. This paranoic checking is not
necessary given there's only one libsha1 in the market, which surely contains
such function.
Moreover, this patch now improves a bit the sha1 implementation checking
behavior using pkg-config to find the right flags that needs to link against.

miDbePositionWindow allocates two pixmaps: a front buffer, and a back buffer.
If the buffers are supposed to be initialized, it validates a GC against the
front buffer, then uses it to fill and/or copy both the front buffer *and* the
back buffer, without revalidating. If the acceleration architecture needs
different GC funcs for the two pixmaps -- for example if allocation of the front
buffer exhausted video memory -- then this can cause crashes because the GC is
not validated for the back buffer pixmap.
Fix this by performing the rendering for the front buffer first, then
revalidating against the back buffer before performing the back buffer
rendering.

For absolute input devices (E.G. touchscreens) in multi-head setups,
we need a way to bind the device to an randr output. This adds the
infrastructure to the server to allow us to do so.
positionSprite() scales input coordinates to the dimensions of the shared
(total) screen frame buffer, so to restrict motion to an output we need to
scale/rotate/translate device coordinates to a subset of the frame buffer
before passing them on to positionSprite.
This is done here using a 3x3 transformation matrix, which is applied to
the device coordinates using homogeneous coordinates, E.G.:
[ c0 c1 c2 ] [ x ]
[ c3 c4 c5 ] * [ y ]
[ c6 c7 c8 ] [ 1 ]
Notice: As input devices have varying input ranges, the coordinates are
first scaled to the [0..1] range for generality, and afterwards scaled
back up.
E.G. for a dual head setup (using same resolution) next to each other, you
would want to scale the X coordinates of the touchscreen connected to the
both heads by 50%, and translate (offset) the coordinates of the rightmost
head by 50%, or in matrix form:
left: right:
[ 0.5 0 0 ] [ 0.5 0 0.5 ]
[ 0 1 0 ] [ 0 1 0 ]
[ 0 0 1 ] [ 0 0 0 ]
Which can be done using xinput:
xinput set-prop <left> --type=float "Coordinate Transformation Matrix" \
0.5 0 0 0 1 0 0 0 1
xinput set-prop <right> --type=float "Coordinate Transformation Matrix" \
0.5 0 0.5 0 1 0 0 0 1
Likewise more complication setups involving more heads, rotation or
different resolution can be handled.

Peter wants to get a larger patch sequence put together and I didn't
read past the commit message to see the 'don't take this patch
please'.
This reverts commit 531ff40301.
Some input drivers need to implement an internal hotplugging scheme for
dependent devices to provide multiple X devices off one kernel device file.
Such dependent devices can be added with NewInputDeviceRequest() but they are
not removed when the config backend calls DeleteInputDeviceRequest(),
leaving the original device to clean up.
Example of the wacom driver:
config/udev calls NewInputDeviceRequest("stylus")
wacom PreInit calls
NewInputDeviceRequest("eraser")
NewInputDeviceRequest("pad")
NewInputDeviceRequest("cursor")
PreInit finishes.
When the device is removed, the config backend only calls
DeleteInputDeviceRequest for "stylus". The driver needs to call
DeleteInputDeviceRequest for the dependent devices eraser, pad and cursor to
clean up properly.
However, when the server terminates, DeleteInputDeviceRequest is called for
all devices - the driver must not remove the dependent devices to avoid
double-frees. There is no method for the driver to detect why a device is
being removed, leading to elaborate guesswork and some amount of wishful
thinking.
Though the input driver's UnInit already supports flags, they are unused.
This patch uses the flags to supply information where the
DeleteInputDeviceRequest request originates from, allowing a driver to
selectively call DeleteInputDeviceRequest when necessary.
Also bumps XINPUT ABI.

InputAttributes largely decide which configuration values get merged from
the xorg.conf.d snippets. While they are available in the config backend,
they are not available for any other callers of NewInputDeviceRequest().
Drivers implementing driver-side hotplugging do not have access to these
attributes and cannot have xorg.conf.d snippets specific to dependent
devices. For example, the following case cannot work right now:
Section "InputClass"
MatchProduct "Wacom"
Option "PressCurve" "0 0 100 100"
...
EndSection
Section "InputClass"
MatchProduct "Wacom"
MatchProduct "eraser"
Option "PressCurve" "10 10 50 50"
...
EndSection
The second section is not triggered, as the wacom driver cannot supply the
InputAttributes to NewInputDeviceRequest().
Add the attributes to the IDevRec and merge them into the InputInfoRec to
make them accessible in the driver. This changes the ABI for input drivers.

Oliver McFadden reports that the invisible cursor sprite caused damage
events and thus unnecessary redrawing, so removing it improves
performance when using software cursor sprites, especially on those
devices where you do not want a visible cursor: touchscreen tablets,
embedded devices, etc.
For the xfree86 DDX, if hardware cursors are used, the driver is
required to provide a HideCursor function, which will be called instead
of trying to set a null cursor. I think software cursors are already
safe. The other DDXes also look safe.
As far as I can tell, there's no reason to realize a null cursor. I
think everything that handles null cursors doesn't rely on any setup in
RealizeCursor, and treats them as empty cursors.
Xnest assumes that if a cursor is created, it will be realized before it
is freed, which didn't happen if the invisible cursor was never used in
a server generation. So this fixes a segfault in Xnest as well.

miDCDeviceCleanup frees any non-NULL GCs. miDCDeviceInitialize calls
Cleanup on any failure, but if it failed early then some of the pointers
in the miDCBufferPtr were garbage. Switch from malloc to calloc to
ensure everything's initialized safely first.

Since the headers we export in the SDK use the _X_NORETURN #define

I considered exporting the version from configure.ac, but decided not
to since the minimum required to build the X server may not always
be the same as the minimum required to build drivers (for instance,
if the X server used a new #define in its .c files or internal headers,
