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
"libswscale_template.c"

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.
