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.

swscale: Readd #define _SVID_SOURCE
...
This was removed erroneously in
046f081b46
. This define still is
necessary for getting MAP_ANONYMOUS defined on linux/glibc,
despite the define reshuffling done in that commit.
Without MAP_ANONYMOUS defined, the mprotect calls for setting the
generated mmx2 scaler code pages executable are left out, causing
crashes if that codepath is chosen.
This patch fixes scaling from 192x144 to 320x240 with
-sws_flags fast_bilinear, which crashes on linux at the
moment.

Fix av_get_channel_layout_string() for positions >31

A value shifted left by >31 needs to have a 64-bit type.
As there are no defined channels in this range, the fix
is purely theoretical at this point, although it does
avoid some invalid shifts triggering the overflow
checker.
