manifest: allow specifying the revlog filename
Previously we had hardcoded the manifest filename to be 00manifest.i. In our
external treemanifest extension, we want to allow writing a treemanifest side by
side with a flat manifest, so we need to be able to store the root revisions at
a different location (in our extension we use 00manifesttree.i).
This patches moves the revlog name to a parameter so we can adjust it.
