cc276c85d1 Make channel layout masks unsigned
It makes more sense for a bit mask to use an unsigned type.
The change should be source and binary compatible on all
supported systems, hence micro version bump.

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.

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.

ea8de109af lavfi: add avfilter_all_channel_layouts public symbol
This list is mainly useful to be directly used as a parameter by the
audio sink buffer, when there is no need to force a specific channel
layout.

The list of formats is generated programmatically, and avoids channel
layouts not supported by libavfilter (with more than 8 channels).

We preferred to avoid compile-time generation in order to avoid some
unnecessary complexity (build hacks, generating code maintainance
etc.).

A more compact way to express this list through the use of macros
should be possible when libavfilter will support more than 8 channels,
as there will be no need to filter out channel layouts with more than
8 channels.

9899037dc6 lavfi: rename avfilter_all_* function names to avfilter_make_all_*

and clarifies the code.

Breaks audio API/ABI, add a backward compatibility layer for video
API/ABI.
