Merge remote-tracking branch 'qatar/master'
* qatar/master:
pixfmt: support more yuva formats
swscale: support gray to 9bit and 10bit formats
configure: rewrite print_config() function using awk
FATE: fix (AD)PCM test dependencies broken in e519990
Use ptrdiff_t instead of int for intra pred "stride" function parameter.
x86: use PRED4x4/8x8/8x8L/16x16 macros to declare intrapred prototypes.
