changelog: prefilter in headrevs()
In case where headrevs() is called on some revisions, we perform
the check that aren't filtered in advance, and switch revlog to
use its unchecked form.
This allows to work with alternative implementations that don't have knowledge
of the filtering system, such as the Rust one.
