If max in clean_index is set to a negative ast->sample_size, the
following loop never ends:
while (max < 1024)
max += max;
Thus set ast->sample_size to 0 if it would otherwise be negative.

s->decoded_buffer is allocated with a min_size of:
2 * FFALIGN(blockstodecode, 8) * sizeof(*s->decoded_buffer)
Then it is assigned to s->decoded[0] (and s->decoded_buffer + FFALIGN(blockstodecode, 8)
to s->decoded[1]) and passed as out buffer to decode_array_0000.
In this function 64 elements of the out buffer are written
unconditionally and outside the array if blockstodecode is too small.
This causes memory corruption, leading to segmentation faults or other
crashes.
Thus change decode_array_0000 to write at most blockstodecode elements
of the out buffer.

Fixes the corner case in which the internal buffer size
is larger than input buffer provided and resizing it
before moving the left over samples would make it write
to now unallocated memory.

If a PAT is finished while a PMT section filter is opened but
not yet finished, the PMT section filter is closed and all
the received data is discarded.
This is usually not an issue but some multiplexers (With very
quick PAT/PMT repetition settings) consistently emit a PMT
section start, then a PAT, and then the rest of the PMT,
causing the aforementioned behavior to result in no PMT being
finished.
In the most pathologic situation the stream information are lost
and the probe fallback miscategorizes subtitles as mp3 audio.
Avoid the issue through eliminating redundant PSI/SI table
updates by checking their version field, which is required by
the standard to be incremented on every change no matter how
minor.

Set this field to TRUE if the audio component is to operate on
little-endian data, and FALSE otherwise.
However TRUE and FALSE are not defined. Since this flag is just a boolean,
interpret all values except for 0 as little endian.
