56dc46a189 riffenc: do not fall back on AVCodecContext.frame_size for MP3
It will not be set unless the codec context is used as the encoding
context, which is discouraged. For MP2, av_get_audio_frame_duration()
will already set the frame size properly. For MP3, set the frame size
explicitly.

194be1f43e lavf: switch to AVStream.time_base as the hint for the muxer timebase
Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).

d754ed4172 riffenc: take an AVStream instead of an AVCodecContext
It will be useful in the following commits.

Also, rename the AVCodecContext pointer name from 'stream' to 'codec'.

c2b0ce70ad Initialize riff and wav size fields to -1 instead of 0.
WMP doess not play the output files if the fields are
set to 0 and not overwritten (using pipe output).

5e7d21c7ad ff_put_wav_header: add flag to force WAVEFORMATEX
Partially undoes commit 2c4e08d893:

    riff: always generate a proper WAVEFORMATEX structure in
    ff_put_wav_header

A new flag, FF_PUT_WAV_HEADER_FORCE_WAVEFORMATEX, is added to force the
use of WAVEFORMATEX rather than PCMWAVEFORMAT even for PCM codecs.

This flag is used in the Matroska muxer (the cause of the original
change) and in the ASF muxer, because the specifications for
these formats indicate explicitly that WAVEFORMATEX should be used.

Muxers for other formats will return to the original behavior of writing
PCMWAVEFORMAT when writing a header for raw PCM.

In particular, this causes raw PCM in WAV to generate the canonical
44-byte header expected by some tools.
