get_uint returns an unsigned value, use an unsigned to store
blocksize to make sure the comparison logic is correct and report
correctly the error for the channel count not supported.
Prevent the loop shorten_decode_close from writing and freeing out of
the array boundary.

This fixes a possible mis-detection of iconv on OS X.
OS X with macports often has two version of libiconv.2.dylib
installed, one with symbols like "_iconv_open" and one with
"_libiconv_open", so test for iconv with all flags to make
sure the detection uses the same library as the actual
compilation / linking.

It should be easy to add support but without a sample we would
not know if they work.

The decoder assumes a single bit depth for all the planes
while the specification allows different bit depths for luma
and chroma.
Avoid the possible problems described in CVE-2013-2277
CC: libav-stable@libav.org
Do not re-call avcodec_get_context_defaults3(), it is already
called by avformat_new_stream() and it leaks the codec
priv_data that was already allocated.
Use avformat_free_context() instead of freeing (not)
everything manually.
Fix trac ticket #2322.
This reverts commit 6cc12353a8.

Allowing to automatically select the concat demuxer raises
security concerns, as it allows a possibly hostile file to
access any file on the system. Guessing the format based on
the file name extension does not allow to enable the safe
mode designed to avoid it.
When parsing the Xing/Info tag, don't set the bit rate if it's an Info tag.
When parsing the stream, don't override the bit rate if it's already set,
otherwise calculate the mean bit rate from parsed frames. This way, the bit
rate will be set correctly both for CBR and VBR streams.
