After making some blind tests on a small collection of music
samples for home usage. It turned out that the default cutoff
was too low.

The impact of filter_size was not clearly distinguishable (the
results were on the edge) with the music samples but turned out
to be clearly audible in some synthetic samples.

Thanks to Daniel for helping out with the listening tests.

Also rename the "enable_auto" field to "deint", to match the name of the
option.

This is better than repeatedly failing during the filtering stage.

The misspelling is used in the specification.

The added statement is not reachable
Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

Some of the filters tests use globbing characters, especially
brackets for filter pad labels. While most of these strings
are way too complicated to ever match an existing file name
and are therefore kept unchanged in the command line (an old
misfeature of the shell language that happens to be convenient
here), at least one use is simple enough to match random files
lying in the current directory. If that happens, the string,
that was meant to be kept verbatim, is replaced by the file
name, and that causes the test to fail (or worse).

This makes RTP custom IO work properly with pure read-only
AVIOContexts as well.

To use this, set sdpflags=custom_io to the sdp demuxer. During
the avformat_open_input call, the SDP is read from the AVFormatContext
AVIOContext (ctx->pb) - after the avformat_open_input call,
during the av_read_frame() calls, the same ctx->pb is used for reading
packets (and sending back RTCP RR packets).

Normally, one would use this with a read-only AVIOContext for the
SDP during the avformat_open_input call, then close that one and
replace it with a read-write one for the packets after the
avformat_open_input call has returned.

This allows using the RTP depacketizers as "pure" demuxers, without
having them tied to the libavformat network IO.

So far, aviocontexts are used either in pure-read or pure-write
mode - full read/write mode doesn't work well (and implementing it
is a much larger, not totally trivial change).

This patch allows using avio_read and ffio_read_partial on
read/write aviocontexts, where the read operations are passed
through directly unbuffered, while writes are buffered as usual.

This is enough to support the operations needed by packet based
data transfer like in udp/rtp, where aviocontext is the only
public API for hooking up custom IO.

The function find_things() in configure is confused by component
registration calls as part of multiline macros defining combined
component registration.  Coalesce those macros into one line to
work around the issue.
