llvm's integrated assembler does not accept spaces as macro argument
delimiter when targeting darwin. Using a explicit delimiter is a good
idea in principle since it makes case like 'macro 4 -2' vs 'macro 4 - 2'
clear.

Add CPU count and number threads as informative values for fate.

libavutil/cpu-test prints raw and effective cpu flags to STDERR. Detected
cpu flags can be useful for debugging fate errors.

No comparison of the result against a expected result since that would
require fate config specific references.

Split return value handling from the actual opening.

Incidentally fixes the https -> http redirect issue reported by
Compn on behalf of rcombs.

This treats mono as planar internally within libavresample rather
than changing the sample format.

Also add missing mem.h header for av_freep().

This is cleaner and avoids a cast plus a related const qualifier warning.

Otherwise the frame would show the first layout matching the
channel count.

And leverage the video index if the video is just disabled as wm4
did in an initial patch.

Properly address CVE-2011-3946 and parse bitstream as described in the spec.

This reverts commit 35b05c51.
A warning is introduced in case this option is used.

The Xvid IDCT is only required to decode some Xvid-encoded MPEG-4 files,
so there is no point in having it as an unconditional part of idctdsp.

This is how all the other init functions operate.

This allows running all the tests individually and/or in parallel.

Make sure the buffer size does not exceed the expected
RLE size.

Prevent an out of array bound write.

Speed up probing ADTS live streams that are not frame-aligned such
as http://mp3.streampower.be/radio1.aac .

It should provide a quicker guess for elementary streams provided
by http.
