If GL context is free'd before processing font shutdown,
textures for emoji glyph's GL images will be free'd without clean
up its GL images. It causes eina mempool infinite loop issue when
emoji's GL images are free'd in shutdown process.
So, the patch will make a list for emoji's GL images in context and
clean up them when the context is free'd. Just like font textures in
context.

so a little perf fun shows malloc/free/realloc/etc. are, combined a
reasonable overhead. this reduced malloc overhead for draw contexts so
whne we duplicate them or create new ones, we re-use a small cache of
8 of them to avoid re-allocation. just take the first one from the
list as it really is that simple. mempool would not have helped more
here and cost more overhead.

i found evas_common_draw_context_apply_cutouts() was procsessing 300+
cutouts and as it's O(n^2)/2 to try and merge adjacent rects for
cutouts this really performs like complete junk. we apply cutout rects
a LOT. this is not the best solution, but it's quick and much faster
than doing the clipouts which drop framerate to like 1-2fps or so in the
nasty case i say (tyls -m of photos in a dir with a 2160 high
terminal).
this figures out the target area to limit the count of rects
significantly so O(n^2) is far far better when n is now < 10 most of
the time. and for the few operations where it's a high value this now
uses qsort to speed up merges etc. etc.
@optimize
Moved rects caching into draw context to avoid the use of __thread
slot. Draw context are defined per thread anyway and should be just
fine. This doesn't really change the picture regarding glibc problem
when to many __thread are needed, but slightly improve the global
picture. Also this patch doesn't affect our performance in expedite
benchmark as far as I can tell.
this works with 7166e6b859 and fixes a
leak added because ... free does not free!
evas_common_draw_context_cutouts_real_free(0 now actually frees the
rects, but evas_common_draw_context_cutouts_free() before did not.
@fix (follow on from 7166e6b859)
Actually copying max is pretty useless and super slow. We usually have something
like 1024 slot in a context, but a very small amount of them are acutally active.
It would be better to actually do some kind of copy on write technique here, but
as Eina_Cow doesn't handle array and we are close to a release, let's be
conservative.
valgrind pointed this one out. we access freed memory when we dup a
context because the context CONTAINS ptrs to things like rects for
cutouts. we didnt dup these. use the proper context dup call (and
properly ref pixman color image too). this was a random bug/crash
waiting to happen and valgrind caught it. suprising it hasnt turned up
before :/
@fix
this optimizes draw ctxt cutouts by skipping small ones and
remembering the last cutout added so it isn't double-added as well as
extending the minimum cutout array to 512 and going up in blocks of
512 instead of 128. also optimize the clipping code a bit more.
This is for now just a small experiment. It was based on the experiment made
with OpenMP. I prefered to only use Eina here as we have already all the infrastructure
to do this nicely and simply. As a result I get a 65% speed improved on average for
the involved scaling operation. The secondary CPU is on my laptop running with a load of
75% percent. I don't have right now the time to do power consumption analysis, but I
think it shouldn't be to bad. I am also not throwing more core at this as we are not able
to use the second core at its max already, so additional core may result in a bigger
energy loss without enough gain.
Summary: The comparison dc with NULL is not necessary. So remove the unnecessary conditional expression.

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.
I've tested make -j 3 install and it works nicely
I've tested expedite with software and opengl xlib,
and it works. Not tested other engines, so please
report any problems (engines or other) on the ML.
TODO: examples and tests, I'll add them later
ISSUE: Eina_Unicode size check. It indirectly depends on
eina_config.h, which is created at the end of the
configure script. So its size is always 0. I don't
know how that size is used, so I can't do a lot,
for now.
