A given packet won't always come in contiguously; sometimes
they may be broken up on chunk boundaries by packets of another
channel.
This support primarily involves tracking information about the
data that's been read, so the reader can pick up where it left
off for a given channel.
As a side effect, we no longer over-report the bytes read if
(toread = MIN(size, chunk_size)) == size

Since the number of channels is multiplied by 36 and assigned to
to a uint16_t, make sure this calculation didn't overflow. (In
certain cases the calculation could overflow leaving the
truncated block_align at 0, leading to divisions by zero later.)

A change in framesize caused a perpetual loss of synchronization.
So read (and use) the frame size from the frame header instead of
setting it only once.

It's not our responsibility to account for other projects'
terrible hacky usage.
Also, it is no longer needed by XMBC, since 78b71d4.

Previously this would have lead to a memcpy(a,a) which violates the
requirement of non overlapping src and dst.

checked for by assert() for the case that some future changes make it possible.
Thus merge just for meta-data

lavf: Make probe_codec return an error code
Conflicts:
libavformat/utils.c
A failure to reallocate should not free the array as it is used
to probe the codec. And failure to reallocate if the following
probe succeeds isnt a fatal error for probe_codec(). Thus this
is only partially merged to ensure probing still is attempted
with the data available.
