concat_in.pts starts at 0 for each segment, so the duration
of the silence was too long, except at the first stitch.

The voice register functions return the same voice structure
upon multiple registration. It causes us two problems:

If we delete a voice without deregistering it, it leaves
a dangling pointer inside the library.

If we delete or unregister a voice at uninit, it may still
be in use by another instance of the filter.

The second problem is solved by keeping an usage counter inside
asrc_flite. This is not thread-safe, but neither is flite itself.

Since the recent changes, movie and amovie are able to deal with more
than one type of stream, so they should be categorized as "multimedia
sources" rather than audio/video sources.

Also define AV_BPRINT_SIZE_* macros before av_bprint_init() declaration,
and mention them in the av_bprint_init() doxy.

we use av_assert0() because the previous code unconditionally

Removes a false dependency on existing contents of the 2nd dst register,
giving better performance for OOE.

Allow substitution of channel pairs in the input for nearby channel pairs in
the output in order to get a closer match. Also weigh LFE channel mismatch
differently to favor matching the same layout without LFE over one less
channel with LFE.

This will give a clearer error message when the error is caused by a
truncated packet.

Reversing the lpc coefficient order simplifies indexing in the filter.

This fixes "make fate-eval" on MSVC builds. Without this, the test outputs
"-1.#NaN" instead of "nan" on MSVS 2010.

there are some technical problems with fate.ffmpeg.org
thus split the subdomain between fate-suite and fate
fate-suite is now (temporary) provided by our main server

until fate-suite.ffmpeg.org is setup to point somewhere
we use fate-suite.avcodec.org
