3a82c8c562 egl_dri2: Enable KHR_gl_texture_2D_image 
Forgot to set the enabled bit when I implemented the extension.

d18d0fdcd8 egl_dri2: Flush before context switch and swap buffers. 
DRI does not define any callback to flush the current context.  GLX
loader simply calls glFlush.  Follow the GLX loader here.

The last commit incorrectly moved the code under an "else".

bbe459b14d egl: Fix eglMakeCurrent with different surfaces. 
0a82fadcdd seems to trigger a bug in
_eglBindContext.  Rework the logics yet again.  It is simpler, and
hopefully correct this time.

0a82fadcdd egl: Make _eglBindContextToSurfaces more readable. 
There is no effective changes given how the function is called.  It is
still not trivial, but it should be more readable and resemble
_eglBindContextToThread a lot.

551bfe7a09 egl: Always return the previously bound context. 
When a newly bound context is the same as the previously bound one,
_eglBindContextToThread should still return the context instead of NULL.
This gives the driver a chance to flush the context.

7d1237bc71 egl: Remove unused _EGL_SKIP_HANDLE_CHECK. 
It was added to skip checking EGLDisplay, EGLSurface, and etc.  It is
never defined and the spec does not allow the checks to be skipped.
Remove it for good.

bef4b476d7 egl: Silence warnings in check/return macros. 
The macros give warnings when compiled with -pedantic.  This commit is
based on a patch by Brian Paul, with minor changes to add do {} while(0)
and rename the check macros.

655f465467 egl: Always lock a display before using it. 
This gives a simple access control to the display.  It is potentially
slow, but a finer grained mutex can always be used in the future.  The
benefit of this simple approach is that drivers need not to worry about
thread-safety.

b3bb180620 egl: eglGetError should return the status of the last call. 
Use macros to record the status of the function call before returning.

f3e03e1277 egl: Add new error checking macros.

5f08eff2a7 egl: Remove egl_xdri. 
egl_xdri steals code from src/glx/x11/.  This makes it broken from time
to time when there is a bigger change to the GLX code.  As egl_dri2 has
been merged, which also functions as a DRI2 driver loader, remove
egl_xdri for good.

bdb9e202de egl: Add macros to define typecast functions. 
There are standard typecast functions that are common to most drivers.
They are used to typecast, for example, an _EGLSurface to a
driver-defined type.

This commits define _EGL_DRIVER_STANDARD_TYPECASTS and
_EGL_DRIVER_TYPECAST that should hopefully save some typings for driver
writers.
