Increase flexibility/consistency.

Also rename recording_time field to time, for enhanced
consistency/readability.

Add list extended format which specifies in the list file the start and
ending time for each segment. This is required to make it available this
information to external tools, avoiding the need to perform file analysis
in the output segments.

Now uses -filter_complex instead of deprecated lavfi/amovie

Make it easier to spot the example. This way it can already be
discovered by scanning the table of contents.

Make the document more consistent.

It might be easier to understand for some people and is a bit more
in line with e.g. OpenSSH documentation. The meaning of the text stays
exactly the same.

Move the lavc/imgconvert functions and rename them as follows:
avpicture_get_size -> av_image_get_buffer_size()
avpicture_fill     -> av_image_fill_arrays()
avpicture_layout   -> av_image_copy_to_buffer()

The new functions have an align parameter, which allows to define the
linesize alignment assumed in the buffer (which is set or read).

The names of the functions are consistent with the lavu/samples API
(av_samples_get_buffer_size(), av_samples_fill_arrays()).

Inspired by MPlayer's af_channels filter and SoX's remix effect.

It joins multiple input streams into one multi-channel output.

This breaks libavfilter ABI.

This function implements a delay using the first available
of the following functions:

- nanosleep()
- usleep()
- Sleep() (Windows)

The conditional #includes in time.c are simplified by including
unistd.h and windows.h whenever they are available rather than
having these lines triggered by specific functions.

-same_quant is not designed to convert between quantizer scales, AFAIK.
