Fix handling of input if not in native endianness, and add support for
9/10-bit output. This allows us to force endianness of YUV420P 9/10bit
in the H264/10bit fate tests, which should fix them on big-endian
systems.
In the loop:
for (i=0; i<dstH; i++) {
int chrI= i*c->chrDstH / dstH;
when i*c->chrDstH > INT_MAX this leads to an integer overflow, which
results in a negative value for chrI and in out-of-buffer reads. The
overflow is avoided by forcing int64_t arithmetic by casting i to
int64_t.
Fix crash, and trac issue #72.

handle_jpeg may update the src/dstFormat variables, this makes sure the
updated version is stored in the context.
This fixes roundup issue 2302.

but worse it did not set up destination dimensions, thus every user
of it would necessarily fail.

instead of requireing being passed through function parameters. This also
makes sws work with AVOptions.

mmap() with MAP_ANONYMOUS requires the file descriptor to be -1 in NetBSD.
Linux just ignores this parameter.

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.

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.
