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.
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.
prefers verbs to be last for function declarations).
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.
- Setenv for egl_platform before we init gl/egl, etc
- Ignore check for NULL surface to indicate destroying (this is all
not need now).

Add comment about NULL surface being passed in.
Fix segfault when we close windows...uartie, this one's for you ;)

For native surface rendering (glX, egl) in gl-backend, if pixel get callback
function is called for native rendering, there is a case where evas will
try to call evas_gl_common_context_flush() to flush its remaining commands
in its command queue while the context is set current to the native surface/
context that is called within the pixel get callback. So, I've added an
engine function that forces a flush before it enters the pixel get callback
function.
At least for wayland, eglGetProcAddress seems to fail to get the
eglQueryString symbol. Not sure if it's the right fix, but brings
wayland_egl back to working again.
Fixes#2301.
