9524cf79df avcodec: add av_get_audio_frame_duration() function.
This is a utility function for the user to get the frame duration based on
the codec id, frame size in bytes, and various AVCodecContext parameters.

6699d07480 avcodec: add av_get_exact_bits_per_sample() function
This only returns bits per sample when it is exactly correct. That is, the
codec contains only raw samples with no frame headers or padding. This applies
to basically all PCM codecs and a small subset of ADPCM codecs.

02beb9826b lavc: deprecate AVCodecContext.sub_id.
In most places where it's used, it's as a pointless write-only field.

Only rv10 decoder actually reads from it, but it stores some internal
version info in it. There is no reason for it to be in a public field.

e9cda85351 avcodec: add duration field to AVCodecParserContext
This will allow parsers to export the duration of the current frame being
output, if known, instead of using AVCodecContext.frame_size.

0bf184e59c Move PS2 MMI code below the mips subdirectory, where it belongs.
Also give a more suitable name to the MMI-optimized IDCT;
it is not PS2-specific, as the name currently suggests.

It is obscure, most likely unused and not bit-exact compared to
libavcodec due to a different IDCT transform algorithm.

bc90199848 lavc: set AVCodecContext.codec in avcodec_get_context_defaults3().
This way, if the AVCodecContext is allocated for a specific codec, the
caller doesn't need to store this codec separately and then pass it
again to avcodec_open2().

It also allows to set codec private options using av_opt_set_* before
opening the codec.

af08d9aeea lavc: add avcodec_is_open().
It allows to check whether an AVCodecContext is open in a documented
way. Right now the undocumented way this check is done in lavf/lavc is
by checking whether AVCodecContext.codec is NULL. However it's desirable
to be able to set AVCodecContext.codec before avcodec_open2().

f5f49a66a2 lavc: reorder AVCodec fields.
Put all private fields at the end and mark them as such so they can be
easily changed/removed.
