rust-discovery: starting core implementation

Once exposed to the Python side, this core object will avoid
costly roundtrips with potentially big sets of revisions.

manipulation of the missing, common and undefined set-like revision
attributes.

Differential Revision: https://phab.mercurial-scm.org/D6231
