This makes the decoder independent of mpegvideo.
This copy of the draw_horiz_band code is simplified compared to
the "generic" mpegvideo one which still has a number of special
cases for different codecs.

Make av_get_codec_tag_string() show codec tag string characters in a more
intelligible ways. For example the ascii char "@" is used as a number, so
should be displayed like "[64]" rather than as a printable character.
Apart alphanumeric chars, only the characters ' ' and '.' are used
literally in codec tags, all the other characters represent numbers.
This also avoids relying on locale-dependent character class functions.

The escape API will be useful to perform escaping programmatically, which
is required when crafting argument strings, and will be used for context
printing as well.
This is based on the ffescape tool code, with a few extensions and fixes.

Not all hwaccels implement all codecs, so using one single list for
multiple such codecs means some codecs will be represented in the list,
even though they don't actually handle that codec. Copying specific
lists in each codec fixes that.

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.
