convert: readd --filemap
To handle merges correctly, this revision adds a filemap_source class
that wraps a converter_source and does the work necessary to calculate
the subgraph we're interested in.
The wrapped converter_source must provide a new getchangedfiles method
that, given a revision rev, and an index N, returns the list of files
that are different in rev and its Nth parent.
The implementation depends on the ability to skip some revisions and to
change the parents field of the commit objects that we returned earlier.
To make the conversion restartable, we assume the revisons in the
revmapfile are topologically sorted.
