Adding _POSIX_C_SOURCE to CPPFLAGS globally produces all sorts of problems
since it causes certain system functions to be hidden on some (BSD) systems.
The solution is to only add the flag on systems that really require it, i.e.
glibc-based ones.
This change makes BSD systems compile out-of-the-box without the need for
adding specific flags manually. It also allows dropping a number of flags
set manually on a file-per-file basis, but were only present to work around
breakage introduced by the presence of _POSIX_C_SOURCE.
Also add _XOPEN_SOURCE to CPPFLAGS for glibc systems. We use XSI extensions
in several places already, so it is preferable to define it globally instead
of littering source files with individual #defines only needed for glibc.
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.

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.
