1f4652068e lavfi: rewrite nullsrc using the code in vsrc_testsrc.c 
Factorize code, extend the functionality of the filter, and make it
return empty buffers. This is useful for filters which ignore the input
frames content.

This is also changing the syntax of the nullsrc source, and dropping the
framerate expression evaluation, which does not look particularly useful.

0ec56d1144 lavfi: fix realloc size computation in avfilter_add_format() 
Replace sizeof((*avff)->formats)
with    sizeof(*(*avff)->formats)

as the size of the array element is given by the pointed element
rather than by its pointer.

In particular fix computation with the pending patch when
sizeof(int64_t) != sizeof(int64_t *).

163854bca0 vf_drawtext: drop text wrapping feature 
Or in other word, do not go to the next line when the text cannot be
rendered within the frame.

The rationale is that wrapping is hard to manage, as it depends on the
position of the text, thus making hard/impossible to compute the size
occupied by the rendered text, and makes the filter behavior
unpredictible with moving text (implemented in a pending patch).

Also the current wrapping code is very limited (for example it splits
words in the middle), and correctly handling wrapping requires much
more complexity (alignment, gravity, word parsing etc.), while
drawtext is meant to be only a thin wrapper around libfreetype, so
such advanced features don't belong here.
