convert: allow the converter_source to say "skip this revision"

If getchanges returns a string, it's assumed to be the id of an
already converted revision.  We map the current revision to the same
revision this converted revision was mapped to.

To allow skipping a root revision, getchanges can return the special
string 'hg-convert-skipped-revision' (a.k.a. common.SKIPREV), which
hopefully won't clash with any real id.

The converter_source is responsible for rewriting the parents of the
commit objects to make sure the revision graph makes sense.
