lavf: use the io_open callbacks for files opened from open_input() as well

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

This also fixes reading gapless metadata when the entries do not start with the
mean atom. Such samples can be found here:

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.

16 bits were definitely not enough and caused artifacts to appear on
images at barely compressed images.

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.

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:

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.

- Enabled creation of timecode tracks for MP4 in the same way as MOV.
- Used nmhd as media information header of timecode track of MP4 instead
of gmhd used in MOV, thus avoiding tcmi also, as recommended above.
- Bypassed adding source reference field for MP4, as suggested above.

The pkg-config file contains all opencv libraries, not only the
neccessary ones.
This change makes it possible to use the libopencv-imgproc-dev Debian
package instead of libopencv-dev, saving about 200 MB of useless
build-dependencies.
In particular one doesn't need to install the parts of opencv that
depend on ffmpeg libraries.
