Use a fixed VBO is not efficient. Some times we may only has less than
100 verts, and some times we may have larger than 4K verts. We change
it to allocate VBO buffer dynamically, and this can bring about 10%
performance gain for both aa10text/rgb10text and some cairo benchmarks.

Computing the composite region at the composite_with_shader is very
inefficient. As when we call to here from the glamor_glyph's temproary
picture, we don't need to compute this region at all. So we move this
computing out from this function and do that at the glamor_composite
function. This can get about 5% performance gain for aa10text/rgb10text.

If a pixmap is a pure in-memory pixmap, we do not need to

Even if a picture's pixmap is a pure in memory pixmap, we still need
to track its format. The reason is we may need to upload this drawable
to texture thus we need to know its real picture format.
As to the MACRO to check whether a pixmap is a picture, we should
check whether the priv is non-NULL before we touch its field.

As now the pixmap may be allocated by DDX and doesn't have a
valid pixmap private field. We must check pixmap private
pointer before touch its field value. If a pixmap doesn't
have a non-NULL private pointer, it doesn't have a valid
FBO.

The original version assumes that each drawable pixmap should
have a valid private pixmap pointer. But this is not true after
we create this libglamor. As the DDX layer may create a pure
software drawable pixmap which doesn't have a private pixmap
pointer.

This is also a function which may direct access pixmaps which

Discussed with Chris and found the previous logic is not
good. Now change it in this commit, this API will just
try to create a textured pixmap from the handle provided
by DDX driver, if failed simply return FALSE without touch
the pixmap. And the DDX driver can choose how to do next
step.

This commit exports all the rest rendering/drawing functions
to the DDX drivers. And introduce some new pixmap type. For
a pixmap which has a separated texture, we never fallback
it to the DDX layer.
This commit also adds the following new functions:
glamor_composite_rects, glamor_get_image_nf which are needed
by UXA framework. Just a simple wrapper function of miXXX.
Will consider to optimize them next few weeks.

During the integration with intel driver, we introduce two
new type of pixmap, one is TEXTURE_DRM, the other is DRM_ONLY.
TEXTURE_DRM means we create a texture bind to the DRM buffer
successfully. And then the texture and the external BO is
consistent. DRM_ONLY means that we failed to create a texture
from the external DRM BO. We need to handle those different
types carefully, so we have to track them in the data structure.

When glamor is rendering pixmaps, and needs to create some
temporary pixmap, it's better to use glamor version create
pixmap directly. As if goes to external DDX's create pixmap,
it may create a external DRM buffer which is not necessary.
All the case within glamor scope is to create a texture only
pixmap or a in memory pixmap.

When create a piccture, we need to attach a pixmap to it.
A pixmap only has a depth, which is not sufficant for glamor.
As in openGL texture only has a few internal formats which
is not sufficant to represent all the possible picture
format. So we always transform the picture format to GL_RGBA.
And when we need to read back the picture, we must know the
original picture format. So we have to override create
and destroy picture to track a pixmap's real picture format
if it is attached to a picture.

For the purpose of incrementally intergration of existing intel
driver, for the GC operations we may don't want to use glamor's
internal fallback which is in general much slower than the
implementation in intel driver. If the parameter "fallback" is
false when call the glamor_fillspans, then if glamor found it
can't accelerate it then it will just return a FALSE rather than
fallback to a slow path.

We want to merge the external glamor code to the xserver, with the
internal history retained. However, we don't want a bunch of
non-building changes along the way, so remove all the build system and
support code outside of glamor for now.
This can't happen when GLX is the backing window system, but can
elsewhere. We may as well protect against it at a high level.
