A number of compilers, for example those from TI and IBM, choke on
these initialisers. The current style is also quite ugly.

vf_overlay: properly sync inputs.

Right now it incorrectly assumes that the frames are sent in the proper
order, which worked with old ffmpeg and avconv versions by accident.

vf_overlay: get rid of pointless messing with timebase.

Output frames correspond 1:1 to input frames on the main input.
So use the main input timebase for output.

It is not used in any filters currently and is inherently evil. If

Merge libavcore into libavutil
...
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
