Make the iff demuxer send the whole audio chunk to the decoder as a
single packet, move stereo interleaving from the iff demuxer to the
decoder, and introduce an 8svx_raw decoder which performs
stereo interleaving.

This is required for handling stereo data correctly, indeed samples
are stored like:
LLLLLL....RRRRRR

that is all left samples are at the beginning of the chunk, all right
samples at the end, so it is necessary to store and process the whole
buffer in order to decode each frame. Thus the decoder needs all the
audio chunk before it can return interleaved data.

Fix decoding of files 8svx_exp.iff and 8svx_fib.iff, fix trac issue #169.

Ease readability.

Create separate fields 8svx_compression (for audio compression), and
bitmap_compression (for video compression), and perform minor related
logging tweaks.

Improve clarity, also simplify the case when both types of compression
are employed in the same file.

Allow to factorize code between av_image_get_linesize() and
av_image_fill_linesizes(), and add missing checks.

Increase robustness.

Fix warnings of the type:
vf_drawtext.c:NNN: warning: missing braces around initializer
vf_drawtext.c:NNN: warning: (near initialization for ‘drawtext_options[X].default_val’)

The feature was dropped after the filter was partially rewritten and
recommitted.

Fix issue #207.

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.

* qatar/master:
  Fix FSF address copy paste error in some license headers.
  Add an aac sample which uses LTP to fate-aac.
DUPLICATE  [PATCH] Update pixdesc_be fate refs after adding 9/10bit YUV420P formats.
