If the egl_surface is different from the current one, it may be that the
it has been destroyed already. Removing the below check (and just
checking for different contexts) will avoid calling makecurrent when
destroying a window. That was always failing anyway.
Should fix https://phab.enlightenment.org/T311 for gl_x11 too.

At least on recent mesa (since commit 9f07ca11c17), it will find the
mentioned symbols but they won't really work, leading to error messages,
and possibly some other errors. So far, I just ifdef'ed the
glGenFramebuffer and glBindFramebuffer functions, but it may require
others to be ifdef'ed too.
This is just a workaround, to fix https://phab.enlightenment.org/T246.
NB: When trying to attach a buffer to a surface, there was a corner
case that could fail in that if we just had 'rects' but count was 0,
then the surface would not get damaged (essentially a call to
wl_surface_damage would get passed 0,0 as the size). This fixes that
problem in that if count is <= 0 now, then we'll damage the whole
surface.

Porting commit f10c108283d9b76708418ba172b9ff0b28a09cd6 to wayland
engine.
Added a feature to dump out a png image before calling SwapBuffers.
To turn on the feature, use the following env vars.
EVAS_GL_SWAP_BUFFER_DEBUG_DIR="dir_name" sets the name of the directory
that the files will be output to and enables the debug mode.
EVAS_GL_SWAP_BUFFER_DEBUG_ALWAYS=1 will enable the writing of the
files every frame. This in effect turns on the swap_buffer_debug
variable, which can be set on or off in gdb for debugging. This will
allow dumping of certain frames without having to dump out a ton of
files to track down one frame.

Since we take the lock at the start of the function, we should release
the mutex lock if we are going to return.

If we get an error trying to "make current" an allocated surface, then
we should free that allocated surface.

In case of render_mode == EVAS_RENDER_MODE_ASYNC_INIT we're jumping
directly to end which then calls
evas_gl_preload_render_unlock(eng_preload_make_current, re);
Make sure re is initialized with the render engine data so we don't
dereference junk.

NOTE: when using Evas_Object image preload infrastructure the GL texture
upload was uploaded from the main loop during the rendering stage. This
could lead to some frame drop during fast animation due to the time needed
to upload that texture.
This patch fix this problem by uploading a small texture quickly (16x16)
and waiting for going back to the main loop to be able to use the same GL
context from another thread to do the texture upload asynchronously without
blocking the main loop.
Evas_Common.h should be used for the public header, and rather rename
evas_common.h internal header to another name.
Sa:
Evas_Common_Header.h -> Evas_Common.h
evas_common.h -> evas_common_private.h
Shouldn't have both Evas_Common.h and evas_common.h because of case
insensitive filesystems.

Also, remove unnecessary if block which was checking for the
Render_Engine pixels_get function as it was previously checked for in
the 'if' above.

Evas_GL Direct rendering is an optimization path that renders
directly to the window if conditions are met. Because evas gl
backend used to re-render the entire screen, evas_gl direct
rendering didin't have to concern with partial region rendering.
Now that partial rendering/swapping has been applied to evas gl-
backend, evas_gl direct rendering also had to take into account
clip regions. in order to properly apply it, some adjustments
were made to the engine functions and etc.
Test 23: load lots of scaled images and draw them
Problem: cs2 fails to load more images at some point. (root cause to be fixed!)
After that, client expects some data, but there is none, so it segfaults.
- Setenv for egl_platform before we init gl/egl, etc
- Ignore check for NULL surface to indicate destroying (this is all
not need now).

Basically, EGL does not define a GL_DRAW_FRAMEBUFFER_BINDING so we
test for that and if not found then define it to be
GL_FRAMEBUFFER_BINDING

If we don't do this, the framebuffer object used on shader_array_flush()
will be wrong.
NOTE: shader_array_flush() should take care of setting the fbo
correctly.
