revlog: make "size" diverge from "rawsize"

Previously, revlog.size equals to revlog.rawsize. However, the flag
processor framework could make a difference - "size" could mean the length
of len(revision(raw=False)), while "rawsize" means len(revision(raw=True)).
This patch makes it so.

This corrects "hg status" output when flag processor is involved. The call
stack looks like:

  basectx.status -> workingctx._buildstatus -> workingctx._dirstatestatus
  -> workingctx._checklookup -> filectx.cmp -> filelog.cmp -> filelog.size
  -> revlog.size
