rust: implement the `Graph` trait for all revlogs

This is trivial and makes all the algorithms relying on the trait usable
for more use cases.

from mercurial.utils import procutil

# XXX: we should probably offer a devel option to do this in blackbox directly
def getuser():
    return b'bob'


def getpid():
    return 5000


# mock the date and user apis so the output is always the same
def uisetup(ui):
    procutil.getuser = getuser
    procutil.getpid = getpid
