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.
After a few patches trying to fix clipping of frame or
non-frame objects the icon finally ended up invisible. Even
if the elm_icon was marked as is_frame, its internal evas
object image would not have the flag set, thus it would be
clipped out.
Solution: Propagate the is_frame flag to all smart children,
not only when setting it but also when adding new members.
A hack with the API indicates that the frame edje is a very
special object that does not propagate the flag.

Test cases (in WL or X with client-side decorations on):
1. elementary_test -to Animation
Resize the window to a small size (eg, 100x100) and observe the
balls overflowing outside the window content part. This tests
unclipped normal objects.
2. elementary_test "Window Plug" (requires also Window Socket)
Drag the handles outside the window, observe overflow in the
framespace area. This tests mapped images ('can_map').
3. elementary_test -to "Gesture Layer"
Drag a photo around. This tests non-image mapped objects.
NOTE: This test is badly broken!
This patch fixes both of those issues. I'm not sure what I'm
breaking, though.
Summary:
Before focusing an object, the intercept focus callback
is called. This callback may ask Evas to focus another object
instead, so it's necessary to check if the seat in question still
have a focused object event after a efl_canvas_object_seat_focus_del() call.

When an object inside a genlist is masked, scrolling would
cause render issues as the mask is not redrawn on move (only
the clip geometry is marked as dirty and recalculated, the
mask pixels are assumed to be well prepared already). As a
result, masked objects in a genlist would not show up
properly once you start scrolling.
This fixes that by hacking into evas a safety test to avoid
unnecessary clipping, and by using parent masks even if they
are not the direct clipper.
Note that no_render is still quite broken (eg. a no_render
mask may cause major issues, even crashes).
This reverts 5917b49f59
Using the multi-seat support, Evas is able to handle multiple focused objects.
This implementation allows one focused object per seat.
This patch introduces new APIs and events to handle this new scenario,
while keeping compatible with the old focus APIs.
See T4749, 11b7cf6b72 introduced an issue and
e1e28ce320 fixed it but caused a massive
performance impact.
This should fix that. Thanks @zmike for the first patch.
Fixes T4840
Summary:
the canvas image is the only one presenting the load api, in all other
implementations you would only see error messages.

so i have been doing some profiling on my rpi3 ... and it seems
memcmp() is like the number one top used function - especially running
e in wayland compositor mode. it uses accoring to perf top about 9-15%
of samples (samples are not adding up to 100%). no - i cant seem to
get a call graph because all that happens is the whole kernel locks up
solid if i try, so i can only get the leaf node call stats. what
function was currently active at the sample time. memcmp is the
biggest by far. 2-3 times anything else.

yeah. it's perf. it's sampling so not 100% accurate, but close to
"good enough" for the bigger stuff. so interestingly memcmp() is
actually in a special library/module (libarmmem.so) and is a REAL
function call. so doing memcmp's for small bits of memory ESPECIALLY
when we know their size in advance is not great. i am not sure our own
use of memcmp() is the actual culprit because even with this patch
memcmp still is right up there. we use it for stringshare which is
harder to remove as stringshare has variable sized memory blobs to
compare.
but the point remains - memcmp() is an ACTUAL function call. even on
x86 (i checked the assembly). and replacing it with a static inline
custom comparer is better. in fact i did that and benchmarked it as a
sample case for eina_tiler which has 4 ints (16 bytes) to compare
every time. i also compiled to assembly on x86 to inspect and make sure
things made sense.
the text color compare was just comparing 4 bytes as a color (an int
worth) which was silly to use memcmp on as it could just cast to an
int and do a == b. the map was a little more evil as it was 2 ptrs
plus 2 bitfields, but the way bitfields work means i can assume the
last byte is both bitfields combined. i can be a little more evil for
the rect tests as 4 ints compared is the same as comparing 2 long
longs (64bit types). yes. don't get pedantic. all platforms efl works
on work this way and this is a base assumption in efl and it's true
everywhere worth talking about.
yes - i tried __int128 too. it was not faster on x86 anyway and can't
compile on armv7. in my speed tests on x86-64, comparing 2 rects by
casting to a struct of 2 long long's and comparing just those is 70%
faster than comapring 4 ints. and the 2 long longs is 360% faster than
a memcmp. on arm (my rpi3) the long long is 12% faster than the 4 ints,
and it is 226% faster than a memcmp().
it'd be best if we didnt even have to compare at all, but with these
algorithms we do, so doing it faster is better.
we probably should nuke all the memcmp's we have that are not of large
bits of memory or variable sized bits of memory.
i set breakpoints for memcmp and found at least a chunk in efl. but
also it seems the vc4 driver was also doing it too. i have no idea how
much memory it was doing this to and it may ultimately be the biggest
culprit here, BUT we may as well reduce our overhead since i've found
this anyway. less "false positives" when hunting problems.
why am i doing this? i'm setting framerate hiccups. eg like we drop 3,
5 or 10 frames, then drop another bunch, then go back to smooth, then
this hiccup again. finding out WHAT is causing that hiccup is hard. i
can only SEE the hiccups on my rpi3 - not on x86. i am not so sure
it's cpufreq bouncing about as i've locked cpu to 600mhz and it still
happens. it's something else. maybe something we are polling? maybe
it's something in our drm/kms backend? maybe its in the vc4 drivers or
kernel parts? i have no idea. trying to hunt this is hard, but this is
important as this is something that possibly is affecting everyone but
other hw is fast enough to hide it...
in the meantime find and optimize what i find along the way.

Evil implementation of pipe() function uses sockets. Windows functions
"write", "read" and "close" doesn't works with sockets. In this commit
added macros, that replace "read" with "recv", "write" with "send" and
"close" with "closesocket".
@fix
so bu5hman pointed out a compile warning from clang that
{ 0x20000, 42711, EVAS_SCRIPT_HAN },
has 42711 exceeding a signed short. true. so this should be an
unsigned short. but this drew me to the fact the whole array could be
shorter by packing this short with the style memeber after it making
them pack into a nicely aligned 4 byte chunk next to the start unicode
value before it, thus chopping 1324 bytes off this table. even worse
the 8192 entry fast table above is using a full 32bits per entry where
they data they store is not even exceeding 7bits, so move this to an
unsigned char saving another 24k. this should reduce cache misses and
memory footprint and binary footprint of the evas .so files etc.
