avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT
Libav, for some reason, merged this as a public API function. This will
aid in future merges.
A define is left for backwards compat, just in case some person
used it, since it is in a public header.

lavfi: replace passthrough_filter_frame with a flag.
With the introduction of AVFilterContext->is_disabled, we can simplify
the custom passthrough mode in filters.
This commit is technically a small compat break, but the timeline was
introduced very recently.
