Iam not sure this is the best way to implement it, but its the simplest
and keeps the code seperate from the application. Keeping ffmpeg.c
simple and not requireing user apps to duplicate this code.

These macros are no longer needed after the s32 output was removed.
Change the relevant code to use av_clip_int16() instead of using
explicit limits.

The size-32 DCT_II has a special implementation which doesn't use
the normal tables. Skipping allocation of these in this case saves
some memory.

Ignore color_type information for setting the monoblack pixel format,
only rely on bit_depth.
In particular: fix Test_1bpp_grayscale.png from issue #172.
This may work fine for some broken encoder, and not for others.
* qatar/master:
aacdec: Use float instead of int16_t for ltp_state to avoid needless rounding.
acelp: Remove unused gray_decode table.
dfa: Remove unused variable.
configure: Include AVX availability in summary output.
configure: use same CPPFLAGS in kFreeBSD as Linux

Make it a subcase of the general algorithm used for the non-bitstream
case. Simplify, and make av_image_get_linesize() and
av_image_fill_linesizes() correctly return the right value when plane
!= 0.
In particular fix a crash occurring with:
-vf format=monow,showinfo,format=monow.
046f081b46 reorganized the CPPFLAGS to no
longer add -D_POSIX_C_SOURCE unconditionally, but only on systems (e.g.,
glibc based ones) that require it. As kFreeBSD uses glibc, it needs to
be treated similar.
Additionally, _BSD_SOURCE is turned on to enable some additional types
such as caddr_t, which are normally enabled on BSD but not with glibc.
Also remove code that overwrites the C versions of functions in
sws_init_swScale_altivec(), so that it uses the C functions of files
if no altivec-optimized version exists.
Surround memset and ff_vp8_dct_cat_prob by X() in order to fix iOS build

* qatar/master:
swscale: properly inline bits/endianness in yuv2yuvX16inC().
(We didnt pull the bug) swscale: fix clipping of 9/10bit YUV420P.
Add av_clip_uintp2() function
(our patch / duplicate) dfa: fix buffer overflow checks to avoid integer overflows.
(our patch / duplicate) movenc: always write esds descriptor length using 4 bytes.
(our patch / duplicate) ffmpeg: use parse_number_and_die() when it makes sense
(No thanks) ffmpeg: get rid of the 'q' key schizofrenia
