The read_packet callback passes a pointer to a stack-allocated AVPacket.
Attempting to free it with av_free() makes no sense.

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.

The allocation didn't account for headers, that can be easily 79 bytes.
As a result, buffers allocated for a few samples (e.g. 5 in the original
bug) could be undersized.
Fixed ticket #2881.
