swscale: fix signed overflow in yuv2mono_X_c_template
...
As old bits are shifted out of the accumulator, they cause signed
overflows when they reach the end. Making the variable unsigned fixes
this.

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.

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.

Instead of using fixed coefficients, the correct way is to calculate the
