67e1d52783 swscale-test: allocate more memory to prevent scalers from writing out of bounds 
Some converters (ie. unscaled rgb24 -> argb) may write some bytes out of
bounds. Ideally the converters should be fixed, but in the meantime we allocate
more memory to prevent heap corruption.

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.

c85007d559 Another try at fixing swscale on win64, as per r31153. 
Don't change paramater passing, but instead use casts.
Shouldn't affect asm output on anything other than win64.
libswscale should work on win64 now.
The rest of ffmpeg still isn't win64 compatible due to the issue of xmm
clobbers, but swscale doesn't use any SSE.

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.

needed for DECLARE_ALIGNED.
Remove dependency from swscale-example.c to swscale_internal.h by duplicating
the necessary code. The duplicated code is a hack and should be removed once a
cleaner pixel format information system exists. swscale-example.c is example
code on how to use the library and therefore shouldn't rely on internal
headers.

	Fix libswscale compilation on non-x86, hopefully without breaking MinGW64 again.

This change was non optimal, correct would have been to revert the offending commits
if no time was available to find a clean fix.

9655ffb59e Convert typeof keyword into __typeof__; this is a gcc extension and the former is not accepted in C99 without GNU extensions enabled (e.g. via -fasm). This fixes compilation on PPC.

7ad6469eae Convert asm keyword into __asm__. 
Neither the asm() nor the __asm__() keyword is not part of the C99
standard, but while GCC accepts the former in C89 syntax, it is not
accepted in C99 unless GNU extensions are turned on (with -fasm). The
latter form is accepted in any syntax as an extension (without
requiring further command-line options).

Sun Studio C99 compiler also does not accept asm() while accepting
__asm__(), albeit reporting warnings that it's not valid C99 synta.

6683a37f89 Invert logic for the single-pass in swScale() functions. 
Instead of having a firstTime variable defaulting to 1, have a
warnedAlready defaulting to 0. While this should make no difference in
code speed at runtime, it allows to aggregate the four bytes of that
variable with clip_table in .bss section, rather than issuing a .data
section just for that.

As it is, libswscale require no .data section but .data.rel.ro (that
can be mitigated by prelinking), so the change might actually save one
page of memory at runtime (per process).
