b033913d1c fftools/ffmpeg: move processing AV_PKT_DATA_QUALITY_STATS to do_video_stats()
This is a more appropriate place for this code, since the values we read
from AV_PKT_DATA_QUALITY_STATS side data are primarily written into
video stats. This ensures that the values written into stats actually
apply to the right packet.

Rename the function to update_video_stats() to better reflect its new
purpose.

9acce2afcf fftools/ffmpeg: stop using av_stream_get_end_pts() in do_video_stats()
It retrieves libavformat's internal dts value (contrary to the
function's name), which is not only incorrect in general, but also
unnecessary because we can access the packet directly.

3d4d355375 fftools/ffmpeg: stop using AVStream.nb_frames in do_video_stats()
Its use for muxing is not documented, in practice it is incremented per
each packet successfully passed to the muxer's write_packet(). Since
there is a lot of indirection between ffmpeg receiving a packet from the
encoder and it actually being written (e.g. bitstream filters, the
interleaving queue), using nb_frames here is incorrect.

Add a new counter for packets received from encoder instead.

4cdc14aa95 libavutil: Deprecate av_fopen_utf8, provide an avpriv version
Since every DLL can use an individual CRT on Windows, having
an exported function that opens a FILE* won't work if that
FILE* is going to be used from a different DLL (or from user
application code).

Internally within the libraries, the issue can be worked around
by duplicating the function in all libraries (this already happened
implicitly because the function resided in file_open.c) and renaming
the function to ff_fopen_utf8 (so that it doesn't end up exported from
the DLLs) and duplicating it in all libraries that use it.

This makes the avpriv_fopen_utf8 / ff_fopen_utf8 function work in
the exact same way as the existing avpriv_open / ff_open, with the
same setup as introduced in e743e7ae6e.

That mechanism doesn't work for external users, thus deprecate the
existing function.

3fb9244642 fftools: Stop using av_fopen_utf8
Provide a header based inline reimplementation of it.

Using av_fopen_utf8 doesn't work outside of the libraries when built
with MSVC as shared libraries (in the default configuration, where
each DLL gets a separate statically linked CRT).

662364b2ef fftools/ffmpeg: stop using OutputStream.frame_number for streamcopy
This field is currently used by checks
- skipping packets before the first keyframe
- skipping packets before start time
to test whether any packets have been output already. But since
frame_number is incremented after the bitstream filters are applied
(which may involve delay), this use is incorrect. The keyframe check
works around this by adding an extra flag, the start-time check does
not.

Simplify both checks by replacing the seen_kf flag with a flag tracking
whether any packets have been output by do_streamcopy().

1728ad8293 fftools/cmdutils: drop redundant code
It allocates a dummy sws/swr context and tries setting options on it,
apparently to check if they are valid. This is redundant, since the
options will be checked if/when they are later applied on a context that
is actually used for conversion.

f2da2e1458 libavcodec: Split version.h
This avoids including version.h in all source files, avoiding
unnecessary rebuilds when the version number is bumped. Only
version_major.h is included by the main header, which defines
availability of e.g. FF_API_* macros, and which is bumped much
less often.

This isn't done for libavutil/version.h, because that header needs
to be included essentially everywhere due to LIBAVUTIL_VERSION_INT
being used wherever an AVClass is constructed.
