revlog: use a "radix" to address revlog Instead of pointing to the index directly and to derive the other file from that, we directly provide the radix and let the revlog determine the associated file path internally. This is more robust and will give us more flexibility for picking this file name in the future. Differential Revision: https://phab.mercurial-scm.org/D10576
