We should not simply set a TEXTURE_DRM pixmap to a separated
texture pixmap. If the format is compatible with current fbo
then it is just fine to keep it as TEXTURE_DRM type and we
can safely fallback to DDX layer on it.

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.

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.
This commit also Fixed a glyphs rendering bug pointed by Chris.

If the dest pixmap is in texture memory, but source pixmap is not.
Then we need to upload the source pixmap to texture memory. Previous
version will upload the whole source pixmap. This commit preprocess
the source pixmap, and reduce it to a smaller tempory pixmap only
contains the required region.

Concentrate the verties and texture coords processing code to a new
file glamor_utils.h. Change most of the code to macro. Will have some
performance benefit on slow machine. And reduce most of the duplicate
code when calculate the normalized coords.
