xxan: fix invalid memory access in xan_decode_frame_type0()
...
The loop a few lines below the xan_unpack() call accesses up to
dec_size * 2 bytes into y_buffer, so dec_size must be limited to
buffer_size / 2.

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.
