in 1 situation at least we delete the eina file (close it) but keep
the ptr around (during destruction) which could cause issues with
callbaks and events on del and so on.... which may lead to multiple
closes where only one should happen ... which would explain my invalid
eina file ref problems i'm seeing. i carefully matched eina file
handle stores/opens/dups to closes in edje/evas and they seemed to all
match up so this audit with comments and fixes seems to have plugged
that now.

Summary:
integrate mman.h to make Evil private to the EFL, as mman.h does not exist on Windows. After a discussion with raster, i include sys/mman.h only on non Windows platform.
One issue, though, is that src/modules/emotion/generic/Emotion_Generic_Plugin.h has inlined functions using mmap()
Test Plan: compilation on Windows

tracking some seemingly not so good asan hits on the eina file where
we're accessing an eina file already closed... so be extra paranoid
about it and set things to null after free/close...
as indicated by the accompanying FIXME, the byte ordering is inverted
for big endian so this should be #ifdef-ed

Summary:
The image.data is set to null by evas_common_rgba_image_unload_real.
After this point the cache->usage does not count cache_entry.w and h value when
evas_gl_common_image_free calls evas_cache_image_flush.
So the cache->usage increases just around 300. If the cache->limit is 4194304,
then the cache could have around 1398 items. This would be fine.
But each items hold eina_file, and the cache does not count eina_file size.
If the file size is 326352, then a process could use 456527385 bytes.
So this patch set make the cache->usage count eina_file size.
This would be better option than https://phab.enlightenment.org/D7029

we can't sensibly use things like massif to track memory if we bypass
itr with mmaping -1 fd anonymous memory... so if built with valgrind
support and running under valgrind, use malloc/calloc and free so
these tools actually do something useful for these bits of memory.
In gl engine, image objects try to unload image's pixel data after creating or updating the texture.
but image entry's reference is still 1, it is added to the pending_unloads list,
and it is cleaned when evas render function.
If elm image use preload feature, preload_done flag is true, so this image data cannot be removed from
pending_unloads list, it cause memory leak.
I think it is better to free image's pixel data in evas_cache_image_unload_data,
(not add to the pending_unloads list)
but it it complicated to modify.
so I'll remove the code to check preload_done flag in evas_common_rgba_pending_unloads_cleanup function.
this flag check was added because of gl preloading, but now gl preloading feature is disabled.
this flag is related with https://phab.enlightenment.org/D2823
I tested photocam, but crash doesn't occur anymore, even though removing flag check.
this doenst change functionality but just cleans up the file
whitespacing and formatting and removed commented out junk, 80 column
wrapping/overflow etc.
This brings support for the eo api for external buffers (like
the old data_set / data_get). The new API now works with slices
and planes.
The internal code still relies on the old cs.data array for
YUV color conversion. This makes the code a little bit too
complex to my taste.
Tested with expedite for RGBA and YUV 422 601 planar, both
SW and GL engines (x11).
Those APIs should provide a cleaner interface than the
old data_set/data_get APIs, by making sure the operations are
atomic (ie. no need to call size_set, cspace_set and then data_set).
padding/duplicated borders are not supported.
TODO: Implement legacy API on top of the new API, instead of
this quick patch
i am not sure if this is the odd crash i am seeing, but in theory it
could be. as these crashes are rare it's hard to find and gdb is "too
late" other than telling me the image is freed already by the time we
do an unload.
Summary:
Now Evas gl preload feature is disabled.
But if it is turned on, memory crash occurs.
Because evas_gl_common_texture_upload is not excuted immediately.

i think this has been disabled for a while. image unloading is broken
- esp with gl enigne as due to async move it was effectively disabled.
this re-enables it. unloading is deferred with a managed list of things
needing unloading and then when any async sw renders are not busy any
more - do the unload then in the mainloop of all pending/flagged
images to unload

if yuou use 709 instead of 601 yuv (ycbcr) evas will just be wrong and
use 601. this fixes that and implements 709. it also fixes a scaling
bug for yuv in the gl engine. no one noticed but me, so i won't call
this a bug fix, and it can go into the next efl release - no need to
backport unless it actually bothers peolpe (which it seemingly doesn't)
Now, the evas loader is supposed to advertise the actual border
size in case of compressed texture formats.
The only case where the border was non zero was ETC formats,
from the TGV loader, so I think we don't need to keep the
previous behaviour (auto-calculate borders for ETC).
configure: fix prerequisite header issue
Summary:
in some platforms like openBSD <sys/socket.h> must be included before
net/if.h
the canonical way to ensure that with autotools is by providing that
fourth directive.
evas: use MAP_ANON instead of MAP_ANONYMOUS
Stupid unpredictable standards (or not so standard).
MAP_ANON exists and is defined almost anywhere unlike MAP_ANONYMOUS
Let's use that for portability's sake (they are practically identical
anyway)

We do have mmap provided by Evil, but there is no implementation yet of
an anonymous map support. Also it is not clear how the memory system of
windows does actually work, so not sure this optimization is relevant
to windows at all. Thus we disable it for the time being and unbreak
the windows support.
- cherry-pick me -
this fixes https://phab.enlightenment.org/T182 as it is an issue with a
surface alloc overwriting an already allocated surface entirely inside
the general software image infra.
