  lavf: use the io_open callbacks for files opened from open_input() as well
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

This commit is no-op. The affected piece of code does not
exist in FFmpeg.

  avprobe: do not call avio_close() on a custom context
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

FATE tests have been updated to patch. They do not differ in
any meaningful way.

  nutenc: do not use AVCodecContext.frame_size
Merged-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

Improves jpeg auto-detection.

This option is typically useful when cross-compiling dynamic libraries
for iOS, with something such as --install-name-dir=@rpath

optimize draw_bar_yuv (slightly faster)
optimize draw_axis (about 2x faster)

This commit redistributes the leftover bytes amongst the top 150 slices
in terms of size (in the hopes that they'll be the ones pretty bitrate
starved).

A more perceptual method would probably need to cut bits off from slices
which don't need much, but that'll be implemented later.

Previously a global average was used. Using the previous quantizer
resulted in a fairly significant speedup as slice size selection settled
down quicker.

The changes in "Incompatible libraries" section are strictly based on
what our configure script says.

 4.5x faster than C float version with autovectorization
10  x faster than C int version
25  x faster than C float version without autovectorization

Fixes large amounts of seeking past EOF, which could be extremely
slow over a network.

Check that the required plane pointers and only
those are set up.
Currently does not enforce anything for the palette
pointer of pseudopal formats as I am unsure about the
requirements.
Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

We do neither document nor check such a requirement
and for application-provided get_buffer2 they could
contain the result of a malloc(0) or whatever value
they had previously.
This fixes a use-after-free in e.g. MPlayer:
https://trac.mplayerhq.hu/ticket/2262
We might want to consider changing the (documented)
API in addition though.

Reported as https://trac.mplayerhq.hu/ticket/2264 but have
not been able to reproduce with FFmpeg-only.
I have no idea what coded_height is used for here exactly,
so this might not be the best fix.
Fixes the following chain of events:
ff_mss12_decode_init sets coded_height while not setting height.
ff_mpv_decode_init then copies coded_height into MpegEncContext height.
This is then used by init_context_frame to allocate the data structures.
However the wmv9rects are validated/initialized based on avctx->height, not
avctx->coded_height.
Thus the decode_wmv9 function will try to decode a larger video that we
allocated data structures for, causing out-of-bounds writes.
