Explicitly set the number of bits per sample to stop
the avi muxer from guessing at 24 bits.
The result is that bits per pixel in the avi stream header
matches what other XSUB muxers produce, such as AVIAddXSubs.exe

Fix coordinates of the lower right corner of the text area.
Note that the coordinates are redundant as the size and
position of the text area are known.
Many decoders (including Sony Playstation 3, VLC and FFmpeg)
ignore the redundant coordinates.
Some hardware decoders need them for correct playback.

Verified on Philips DVD player models HTS7201 and DVP3380.

Fixes ticket #3031

This allows collecting statistics on probing scores and the amount of data
probing needed for various files and formats.
For example it can be used to find out which formats tend to need more
data for probing or which files are probed with less certain/lower scores

After this patch, if a packet contains multiple teletext pages, the teletext
decoder can return the fist page and store the remaining pages in memory, and
return them to the user on the next calls to avcodec_decode_subtitle2.
