dirstate: separate 'lookup' status field from others

The status tuple returned from dirstate.status() has an additional
field compared to the other status tuples: lookup/unsure. This field
is just an optimization and not something most callers care about
(they want the resolved value of 'modified' or 'clean'). To prepare
for a single future status type, let's separate out the 'lookup' field
from the rest by having dirstate.status() return a pair: (lookup,
status).
