This commit uses int types instead,
it's safe to apply also for previous versions since
WebRtc_Word16 was always a typedef of int16_t and
WebRtc_UWord16 a typedef of uint16_t

9fc7de8d80 avcodec: fix aac/ac3 parser bitstream buffer size
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.
