The size check must be updated to take into account both manners
in which v_data_size might be set.

The pixel format is not known until the frame header is parsed.
Guessing it here only causes trouble for the caller if the guess
turns out to be wrong (and actually causes very wrong output by
avconv/avplay).

This also allows for removing some of the buf_size checks and using the
sample count for some of the decoding loops.

ADPCM IMA WAV decoder.

There are still 2 nibbles to decode once the last byte in the packet has been
read. Updated FATE reference.

This is already done by avcodec_decode_audio3()

The low 32 bits of a multiplication are the same for signed
and unsigned operands.  Casting to unsigned before multiplying
is thus equivalent while avoiding signed overflow, which is
undefined by the C99 standard.

Fix the fate ref for prores-422_proxy by reverting the changes to it

Also correct CRCs for Sequence_1-Apple_ProRes_422_Proxy.mov, previous
CRCs were generated with the non-bitexact x86_64 assembler IDCT.

The cbSize field should be included in all cases, even with PCM where
its value is ignored.

Fixes encoding PCM audio in Matroska for some players which insist on
a full WAVEFORMATEX structure for A_MS/ACM audio.

Since fate uses wav files for the audio test a larger number of tests
has changed checksums or shifted positions due to the 2 byte longer
wave header.

The shorten decoder does not support seeking.

The demuxer does not read the seektable, a parser is not possible without a
full decode, and no shorten decoder can handle random seeking because it needs
side info from the seektable.

This will prevent seeking by bytes for formats that cannot handle this.

This prevents flushing the packet buffer when the input format does not
support seeking.

increment the 'buf' pointer instead, and consume the whole packet.
