storageutil: extract filelog.cmp() to a standalone function
As part of implementing an alternate storage backend, I found myself
reimplementing this code.
With a little massaging, we can extract filelog.cmp() to a standalone
function.
As part of this, the call to revlog.cmp() was inlined (it is just a
2-line function).
I also tweaked some variable names to improve readability. I'll
further tweak names in a subsequent commit.
