If an URLContext is passed in, its ownership is given to this
function, and is either owned by the returned AVFormatContext
on a successful return, or freed on failure.

This allows the caller to set it, and allows the caller to query
what it was set to.

Update the documentation according to the latest changes

JSON usage is quite widespread.

Make the output valid INI serialization.

Do not use decimals if not needed.

The application component can have a subcomponent to specify the
application instance even if it doesn't have a ":" in the playpath.

TARGET_EXEC allows running FATE on simulators, remote targets and
memory checkers. Also document a known issue with Wine and mixed
Unix/Windows line ending.

It's left over from stsd v0. QuickTime 7 no longer writes 'wave' or 'enda'
when 'lpcm' is the audio tag.

The sample_rate variable is used for checks for audio format
changes at the end of the function.

This fixes cases where the sample rate was set from the codec
id by flv_set_audio_codec (as for nellymoser 8 kHz/16 kHz),
so the value set to last_sample_rate wasn't equal to sample_rate
at this point. This caused the demuxer otherwise reports a spurious
change to 5512 Hz and back to the correct one.

Updating channels in the same way is only done for consistency.
Currently, flv_set_audio_codec doesn't update that value.

poll_frame()/request_frame() are used for audio too.

Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

Link properties have to be checked after config_props() is called to
make sure everything is sane, so the default config_props() for output
links was redundant.

Remove now empty defaults.c

Those functions do only decoding now, encoding is run from
poll_filters().

Fixes an invalid write.

This is needed for older versions of yasm/nasm that do not support AVX.
