Also break some long lines, remove codec function placeholder comments
and add spaces in sample/pixel format lists.

Since the mandatory memcpy in vsrc_buffer has been eliminated, there
shouldn't be any significant reason to build without lavfi anymore.

This will make upcoming support for complex filtergraphs easier to do.

It can take a long time before subtitles or data streams show up,
so we shouldn't wait for those before assuming we have all info
for streams.

If get_filtered_video_frame failed above, tb might not be
initialized at all, so don't scale using it.

This fixes cases where avplay could crash if aborting
avformat_find_stream_info with ctrl+c.

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has been replaced by av_get_default_channel_layout().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.
