If an idle_exiter created a recursive main loop (just called
ecore_main_loop_begin()), then this recursive main loop should
continue to process idle_exiters from there and on, thus
idle_exiter_current was added. When going back from recursion, the
current iterator should be updated properly.
This patch also fixes the deletion of idle_exiters from recursive
main loops by reference counting them. This way, the node will not be
free()d inside inner loop cleanups and then crash when going back to
outer loop.
The following test case used to crash but not anymore:
#include <Ecore.h>
#include <Eina.h>
static int _log_dom;
#define INF(...) EINA_LOG_DOM_INFO(_log_dom, __VA_ARGS__)

if using ecore_main_loop_begin() multiple times (reentrant/recursive)
with glib doing threads, then it would deadlock since the same thread
would get the lock it already have.
multiple ecore_main_loop_begin() is required to implement WebKit's
alert/confirm/prompt dialogs since there is no async reply with
callbacks, rather one must return the value.

Don't include the rather large dither tables if small dithering code

* OpenGL ES : 2.0
* OpenGL desktop : >= 1.4
If OpenGL ES 3.* is out, this code must be fixed
If there are problems with the minimal version on desktop,
we will have to increase the minimal version.
Question: should we check GLSL version on desktop ?

* must disconnect connected callbacks, particularly those to
canvas. The object we previously connect will die anyway, but
canvas continues alive, dispatching its
EVAS_CALLBACK_CANVAS_FOCUS_IN and EVAS_CALLBACK_CANVAS_FOCUS_OUT,
causing nasty segmentation faults!
* must call _edje_clean_objects() *AFTER* the entry is shut
down. Otherwise ed->evas will be NULL and
evas_event_callback_del_full() will fail. I left extra checks on
those, since this call will return the given data (in our case
"ed") and NULL when callback connection was not found.
* flag existence of entries and if they were already initalized and
shutdown before, avoid redoing such work.
This fixes a stupid crash that bugged editje for a while now.
