Restore behavior of identifying files with huge id3 tags as
mp3 at AVPROBE_SCORE_MAX/4. This was broken in r25378 and subsequently
removed in r25929.

This only encourages our users to put id3v2 tags on non-mp3 files to opt
into extension based probing.

Locking the decoder against channel config changes in
parse_adts_frame_header() seems to be unnecessary and
streams with channel config changes are reported.

The sample in http://roundup.libav.org/issue999 still works.

This avoids having to convert all input data from int16 to float, which is used
internally for encoding.

instead just print a warning

avoids silently truncating the output

Fix segfault on emu edge, to reproduce

Still be less verbose about channel count change from 0 channels.

Only inform the user that the number of channels changed if it was set
before.

this allows for checking against the actual output size instead of max size.

Also fix some undefined unsigned/signed conversions.
