With the following additions:
* support to gray format
* support to yuva420p format
* parametric luma/chroma/alpha radius
* consistency check on the radius values, avoid crashes with invalid values

Since both the fixed-point and floating-point encoders use the FFTContext,
this no longer needs to be in a separate context. Also, when a short-transform
context is added, the same MDCT window will be used.

ic is NULL in case of error.

Moving the search and parsing of the 'fmt ' info the main loop of
wav_read_header() allows tags that precede it to be parsed.  Creating
wav_parse_fmt_tag() makes wav_read_header() easier to read.

Sometimes it makes sense to replace a raw URL with some informative text
that links to the URL instead of using the raw URL itself in the text.
Also transform some mailing list references into links.

This resolves a circular dependency between the headers.

This fixes some warnings about unused-but-set variables.

Resetting it on codec init would incorrectly clear the values
if av_find_stream_info was already run before, in particular
breaking ffplay.

This fixes trac tickets #213 and #262.

It's replaced by 'creation_time' metadata tag.

It's broken with multiple files or audio streams.

It's broken with multiple files or audio streams.

It's a better format and we have an encoder for it, so it doesn't fail
like CODEC_ID_TEXT.
