Michael Niedermayer 635d4aed60 Split alloc and init of context so that parameters can be set in the context 
instead of requireing being passed through function parameters. This also
makes sws work with AVOptions.

Grant Carver 53bc0dc2bd fix anonymous memory mapping for NetBSD 
mmap() with MAP_ANONYMOUS requires the file descriptor to be -1 in NetBSD.
Linux just ignores this parameter.

Ramiro Polla 262b6dbad9 darwin: allow 64-bit darwin to allocate executable memory 
darwin requires _DARWIN_C_SOURCE to be defined for MAP_ANON, which is used by
swscale to determine whether to use malloc() or mmap(). 64-bit darwin does not
have an executable heap, so mmap() must be used instead of malloc(), and
therefore _DARWIN_C_SOURCE must be defined.

This is of course done with permissions from the authors. The only GPL
component left are MMX optimizations for YUV to RGB conversion.

Stefano Sabatini af0e662169 Declare support for the pixel formats: 
PIX_FMT_YUVJ420P
PIX_FMT_YUVJ422P
PIX_FMT_YUVJ440P
PIX_FMT_YUVJ444P

in the isSupported{In,Out} macros.

These pixel formats are not true pixel formats but hacks specific to
JPEG in libavcodec. They are deprecated and should be removed (that is
from libavcodec first and libswscale second)...  but they must be
tested by swscale-test.
