Ayose 016d767c8e lavfi: add drawvg video filter. ...

The drawvg filter can draw vector graphics on top of a video, using libcairo. It
is enabled if FFmpeg is configured with `--enable-cairo`.

The language for drawvg scripts is documented in `doc/drawvg-reference.texi`.

There are two new tests:

- `fate-filter-drawvg-interpreter` launch a script with most commands, and
  verify which libcairo functions are executed.
- `fate-filter-drawvg-video` render a very simple image, just to verify that
  libcairo is working as expected.
