Most use cases just got the buffer from the texture
and then called into one of the get_handle functions.
Also with this patch it would be easier to move to a
generic function for getting handles from textures
and textures from handles, that is exposed via the screen.

This is to allow a driver to drive multiple displays.

At least its better then hardcoded to i915

Move some fields of _EGLDriver to _EGLDisplay. It also becomes
unnecessary to pass _EGLDisplay to drivers when _eglMain is called.

The motivation is so that drivers do not need to look up and check for
bad display, context, and etc. It also becomes unnecessary for drivers
to call the link functions.
This commit makes eglapi.[ch] do the lookup and check. As a result, the
driver API is overhauled, and almost all sources and drivers need
update. The updates are mainly find and replace with human brains.

IsBound tells if a context or surface is current. What it does not tell
is, to which thread a context is current, or to which context a surface
is current. This commit replaces IsBound by a pointer to the binding
thread or context.

A context or surface that is neither linked to a display nor current to
a thread should be destroyed. Therefore, an unlinked context or surface
implies a pending delete automatically.

This commit uses the newly introduced link functions to manage EGL
contexts and surfaces. As a result of this, the API for drivers are
changed. All drivers are updated for the change.

Make it possible to pass state-tracker-specific data to the
init_screen function, and even open the door for device-specific
state-tracker screen initialization.

There is a wonderful bug in 2.6.29 that causes a hard lock on my
computer when this code is active for lvds that are turned off.

I should have gotten most uses and implementation
correctly fixed, but things might break.
Feel free to blame me.

The core reference counting code is centralized in p_refcnt.h.
This has some consequences related to struct pipe_buffer:
* The screen member of struct pipe_buffer must be initialized, or
pipe_buffer_reference() will crash trying to destroy a buffer with reference
count 0. u_simple_screen takes care of this, but I may have missed some of
the drivers not using it.
* Except for rare exceptions deep in winsys code, buffers must always be
allocated via pipe_buffer_create() or via screen->*buffer_create() rather
than via winsys->*buffer_create().

The incoming CFLAGS already has -fPIC and -Wall. Don't want -g here either.

If a path is in CFLAGS when building and that path contains gl.h
then the wrong gl.h is used when building. This can lead to very
confusing errors. The solution is rather than postpend the CFLAGS
we prepend the paths as expected allowing compilation to occur
as intended

With the pixman CFLAGS at the beginning of the command line, my build
was picking up the glcore.h from glproto, which doesn't have any of the
TFP fields in __GLcontextmodes.

move it to pipe/internal/p_winsys_screen.h and start converting
the state trackers to the screen usage

This works on top Gallium and KMS. The only thing that
does not work currently is swap buffers for shown mesa
screens. So the only fun thing this will produce is a
white screen.
The driver wishing to us the state_tracker needs to
implement the intrace as define in drm_api.h located
in gallium/include/state_tracker. And also have a
working KMS implementation.
