rebase: display an error if --root and --fork-point are both provided

--root implies we want to rebase all commits since the beginning of
history.  --fork-point means we want to use the reflog of the specified
upstream to find the best common ancestor between <upstream> and
<branch> and only rebase commits since that common ancestor.  These
options are clearly contradictory, so throw an error (instead of
segfaulting on a NULL pointer) if both are specified.
