Major refactoring.
1. Rewrite the pixmap texture uploading and downloading functions.
Add some new functions for both the prepare/finish access and
the new performance feature dynamic texture uploading, which
could download and upload the current image to/from a private
texture/fbo. In the uploading or downloading phase, we need to
handle two things:
The first is the yInverted option, If it set, then we don't need
to flip y. If not set, if it is from a dynamic texture uploading
then we don't need to flip either if the current drawing process
will flip it latter. If it is from finish_access, then we must
flip the y axis.
The second thing is the alpha channel hanlding, if the pixmap's
format is something like x8a8r8g8, x1r5g5b5 which means it doesn't
has alpha channel, but it do has those extra bits. Then we need to
wire those bits to 1.
2. Add almost all the required picture format support.
This is not as trivial as it looks like. The previous implementation
only support GL_a8,GL_a8r8g8b8,GL_x8r8g8b8. All the other format,
we have to fallback to cpu. The reason why we can't simply add those
other color format is because the exists of picture. one drawable
pixmap may has one or even more container pictures. The drawable pixmap's
depth can't map to a specified color format, for example depth 16 can
mapped to r5g6b5, x1r5g5b5, a1r5g5b5, or even b5g6r5. So we can't get
get the color format just from the depth value. But the pixmap do not
has a pict_format element. We have to make a new one in the pixmap
private data structure. Reroute the CreatePicture to glamor_create_picture
and then store the picture's format to the pixmap's private structure.
This is not an ideal solution, as there may be more than one pictures
refer to the same pixmap. Then we will have trouble. There is an example
in glamor_composite_with_shader. The source and mask often share the
same pixmap, but use different picture format. Our current solution is to
combine those two different picture formats to one which will not lose any
data. Then change the source's format to this new format and then upload
the pixmap to texture once. It works. If we fail to find a matched new
format then we fallback.
There still is a potential problem, if two pictures refer to the same
pixmap, and one of them destroy the picture, but the other still remained
to be used latter. We don't handle that situation currently. To be fixed.
3. Dynamic texture uploading.
This is a performance feature. Although we don't like the client to hold
a pixmap data to shared memory and we can't accelerate it. And even worse,
we may need to fallback all the required pixmaps to cpu memory and then
process them on CPU. This feature is to mitigate this penalty. When the
target pixmap has a valid gl fbo attached to it. But the other pixmaps are
not. Then it will be more efficient to upload the other pixmaps to GPU and
then do the blitting or rendering on GPU than fallback all the pixmaps to CPU.
To enable this feature, I experienced a significant performance improvement
in the Game "Mines" :).
4. Debug facility.
Modify the debug output mechanism. Now add a new macro:
glamor_debug_output(_level_, _format_,...) to conditional output some messages
according to the environment variable GLAMOR_DEBUG. We have the following
levels currently.
exports GLAMOR_DEBUG to 3 will enable all the above messages.
5. Changes in pixmap private data structure.
Add some for the full color format supports and relate it to the pictures which
already described. Also Add the following new elements:
gl_fbo - to indicates whether this pixmap is on gpu only.
gl_tex - to indicates whether the tex is valid and is containing the pixmap's
image originally.
As we bring the dynamic pixmap uploading feature, so a cpu memory pixmap may
also has a valid fbo or tex attached to it. So we will have to use the above
new element to check it true type.
After this commit, we can pass the rendercheck testing for all the picture formats.
And is much much fater than fallback to cpu when doing rendercheck testing.

This commit fixed two bugs when one client reset the connection.
The first is that we should reopen the graphic device when the previous
node was closed during the screen closing. The second one is we should
call glamor_close_screen (not the ddx version) prior to call
eglTerminate(). As eglTerminate will release the share library. And
the glamor_close_screen may still need to call openGL APIs and thus
will hit segfault. And renamed the ddx functions to avoid naming
conflications with the glamor functions.
GC is redefined in the X11/Xlib.h and include/gcstruct.h which is
a xorg header file. Just use a macro to simply avoid the conflict.
Need revisit latter to find a correct way to fix this problem.
Due to the coordinate system on EGL is different from FBO
object. To support EGL surface well, we add this new feature.
When calling glamor_init from EGL ddx driver, it should use
the new flag GLAMOR_INVERTED_Y_AXIS.
As current glamor implementation depends on the glx library in the
mesa package which is conflict with the version in xorg. We have to
--disable-glx when build Xephyr. But this leads to the linking error
here. We comment out the calling to ephyrHijackGLXExtension() now.
Need revisit latter.
This should avoid a bunch of absurdity with GLX front buffer handling,
fix exposes, and improve performance. For now we're copying the whole
buffer while glamor is developed.
Swapping the wrong size was never caught because swap{l,s} are macros.
It's clear in the case of Xext/xres.c, that the author believed
client_major/minor to be CARD16 from looking at the code in the first
hunk.
v2: dmx.c fixes from Keith.

This allows ddx to set swap_limit if there is more than one back
buffer for drawable. Setting swap_limit has to also check if change
affects a client that is blocked.
This can be used to implement N-buffering in driver with minimal
logic in allocation and selecting next back.

This change isn't relevant to the similar code in
