lavfi: add outlink helper functions.
...
These wrappers cost nothing, they make the namespace more
consistent and they will be useful if/when locking becomes
necessary.

lavfi: make FFERROR_NOT_READY available to filters.

I am not entirely sure that this return code is useful,
but having and using it makes no harm.

lavfi: implement ff_inlink_make_frame_writable().
...
Unlike av_frame_is_writable(), it uses the link's alloc callback,
making direct rendering possible.
The code comes from ff_filter_frame_framed(), moved with mostly
trivial changes.
