aaf47bcde7 Drop ALT_ prefix from BITSTREAM_READER_LE name.
The prefix is a historic remnant that probably meant "alternative".
Now that the A32 bitstream reader has been dropped it makes no sense anymore.

01042d4123 lavc: set defaults in internal codec frames
This is required specifically for setting frame->format to -1,
otherwise it will be set to 0 = PIX_FMT_YUV420P and code reading
the format from the output decoded frame will get misled.

In particular fix regressions occurring with the pending vsrc_buffer
patch.
