Merged-by: Michael Niedermayer <michaelni@gmx.at>

In some cases, in particular if several blocks are needed because of
the channel layout (e.g. 2.1), the information used to write the
trailing bits terminating the sample data was not reset.

This would cause potential desync on the decoder, although decoded
samples were actually mostly fine.

Fixes ticket #3879.

This means container and codec disagree. The codec is supposed to
know better so this could be an error instead.

It is hardcoded to 15fps.

At least one FATE sample contains such chunks and happens to work simply
by accident (due to find_stream_info() swallowing the error).

MpegEncContext based decoders are only fully initialized after the first
ff_thread_get_buffer() call. The RV30/40 decoders may fail before a frame
buffer was requested. ff_mpeg_update_thread_context() fails on half
initialized MpegEncContexts. Since this can only happen before a the
first frame was decoded there is no need to call
ff_mpeg_update_thread_context().

Currently, the encoder will try to reduce it down to 150000, but the
decoder will complain starting at 131072 (WV_MAX_SAMPLES). Therefore,

Buffers containing copies of the AAC and AC3 header bits were not padded
before parsing, violating init_get_bits() buffer padding requirement,
leading to potential buffer read overflows.
This change adds FF_INPUT_BUFFER_PADDING_SIZE bytes to the bit buffer
for parsing the header in each of aac_parser.c and ac3_parser.c.

Some streams were found to have what appeared to be truncated SPS.
Their syntax seem to be valid at least until the end of the VUI, so
try that syntax if the parsing would overflow the SPS in the
conforming syntax.
