ea540401d6 swscale: fix byte overreads in SSE-optimized hscale(). 
SSE-optimized hScale() scales up to 4 pixels at once, so we need to
allocate up to 3 padding pixels to prevent overreads. This fixes
valgrind errors in various swscale-tests on fate.

6a92551234 lsws: remove optimization debug logs in sws_init_context() 
The logged information is possibly false, and it tends to be outdated
after each change since the logging code needs to be manually updated.

Simplify and prevent confusing wrong debug messages.

347167ecf5 lsws: use array for storing the supported in/out information 
Also remove the unnecessary isSupportedIn/Out macros.

Make the code more compact/readable, and simplify the access to
lsws-specific pixel format information.

62ee0e6a97 Revert "swscale: use 15-bit intermediates for 9/10-bit scaling." 
This reverts commit ac0fb59348. It
causes valgrind errors which I'll want to investigate before
resubmitting this.

8a8d0ce208 swscale: for >8bit scaling, read in native bit-depth. 
For 9/10bit, it means we don't have to upscale to 16bit before
actual scaling or pixel format conversion, and thus a performance
gain.

ef1ee362b3 swscale: implement >8bit scaling support. 
This means that precision is retained when scaling between sample

9/10/16bit YUV).

6d4d483eee swscale: de-macro'ify RGB15/16/32 input functions. 
Inline functions are easier to read, maintain, modify and test,
which justifies the slightly increased source size. This patch
also adds support for non-native endianness RGB15/16 and fixes
isSupportedOutput() to no longer claim that we support writing
non-native RGB565/555/444.

Altivec sws code intentionally overreads buffers for better performance,

046f081b46 configure: Do not unconditionally add -D_POSIX_C_SOURCE to CPPFLAGS. 
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.

c8f487deae swscale: fix YUV420P 9/10bit support. 
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.

but worse it did not set up destination dimensions, thus every user
