8540dcfd7a snow: fix integer overflows
The way these values are used, they should have an unsigned type.
A similar change was made for mpegvideo in cb66847.

9d2dd356c2 adx: rename ff_adx_decode_header() to avpriv_adx_decode_header()
It is used by the ADX decoder, and therefore needs to be exported in order to
work with shared libs.

27360ccc5e adx: add an ADX parser.
This simplifies the decoder so it doesn't have to process an in-packet header
or handle arbitrary-sized packets. It also fixes decoding of files with large
headers.
