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.
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.
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’)
Redesign the way -aspect option is handled. This is done by making
ffmpeg read the sample aspect ratio set in the corresponding input
stream by default, and overriding it using the value specified by
-aspect.
If the output display aspect ratio is specified with -aspect, it is
set at the end of the filterchain, thus overriding the value set by
filters in the filterchain.
This implementation is more robust, since does not modify the
filterchain description (which was creating potential syntax errors).

Another aspect ratio fix try. This leaves the setdar addition at the end
(preferred by people).
(Cherry-pick e7c7b0d000)
This fixes several bugs like multiple outputs and -aspect mixed with -vf

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
