Unsurprisingly, if a timing-less subrip decoder is desireable, an
encoder is as well. With this in place, we can move on to remove
the use of the old encoder/decoder with embedded timing and move
all timing handling the (de)muxer where they belong.

Note that the symbols used to run the hardware decoder in asynchronous mode
have been marked deprecated and will be dropped at a future version bump.

This change introduces a basic encoder for 3GPP Timed Text subtitles,
also known as TX3G, Quicktime subtitles, or "movtext" in the existing
code.

This initial change doesn't attempt to write styling information,
and just writes the plain text of the subtitles. I intend to add
support for styles eventually, but it's challenging due to a lack
of existing players that support them.

Note that an additional change is required to the mov/mp4 muxer to
write empty subtitle packets to indicate subtitle duration.

At the moment it only does BGR24, but I plan to add the rest after.

This is required otherwise it is not always possible to guess the number
of channels from the layout, for example if the channel layout is
unknown.

The number of pixel formats outgrew the number of available bits in
the bitmask used in avcodec_find_best_pix_fmt().
avcodec_find_best_pix_fmt2() uses a PIX_FMT_NONE terminated list
of pixel formats instead.

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()).

Rationale is the same as for video width/height etc.

Compared to av_opt_ptr, accessors bring:

- better performance (negligible);
- compile-time type check;
- link-time existence check
  (or at worst, a dynamic linker error instead of a NULL dereference).

Fixes ticket #1220.

Based on my MicroDVD->ASS conversion code from MPlayer
(sub/subassconvert.c).
