add spaces in codec_tag declarations.

It is not public because the header is not installed, and its functionality
has been replaced by av_get_default_channel_layout().

Also, use the new function in the AC-3 encoder.

All the more required since the users are pure SSE functions.

pthread_cond_wait is supposed to return an integer,
and indeed does sometimes. Fix its function declaration
to match its behavior and POSIX.

I.e. just pass the buffer along when src parameters == dst parameters.

Current code, with a filterchain such as
(input - yuv411) -> (scale - any) -> (sink - any)
will result in yuv420 being chosen for the second link, which is clearly
not right.

This commit attempts to improve in the following way:
repeat until convergence:
  loop over all filters
    find input link with exactly one format
    force this format on all output links of the same type (if possible)

It will be used for logging, possibly also AVOptions.

In v2.4, the length includes the length field itself.

Fixes a floating-point exception further down.

The square is always passed as 1 whenever the function is called and
thus the if block never gets executed.

The previous condition of 0 page size was wrong,
that would disable the mechanism for all frames at
a start of a page, thus some keyframes still would not
get their own granule.
The real problem is that header packets must not be flushed,
but they have (and must have) 0 granule and thus would
be detected as keyframes.
Add a separate parameter to mark header packets.

When set, if an Ogg stream buffer has enough data, a page is made
instead of filling maximum-size pages. Using smaller pages results
smaller seek intervals at the expense of higher container overhead.

Also drop the now unnecessary ff_ prefix from its name.

av_dump_format needs the codecs opened in order to print
them.

av_init_packet does not reset data and size fields in AVPacket,
avcodec_encode_audio2 can use preallocated AVPacket.
