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.

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

This fixes the warning:
libavcodec/dfa.c:189: warning: unused variable ‘frame_end’

Indeed the Adler-32 checksum, which is computed by showinfo, is not
cyclic, so using the term "CRC" is wrong/confusing.

Previously the code was computing the checksum only for the first line
of each plane.

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.

046f081b 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.

Compiling "swscale.c" breaks on MINGW32 because of multiple including

Also remove code that overwrites the C versions of functions in
sws_init_swScale_altivec(), so that it uses the C functions of files
