largefiles: more safe handling of interruptions while updating modifications
Largefiles are fragile with the design where dirstate and lfdirstate must be
kept in sync.
To be less fragile, mark all clean largefiles as unsure ("normallookup") before
updating standins. After standins have been updated and we know exactly which
largefile standins actually was changed, mark the unchanged largefiles back to
clean ("normal").
This will make the failure mode more safe. If interrupted, the next command
will continue to perform extra hashing of all largefiles. That will do that all
largefiles that are out of sync with their standin will be marked dirty and
they will show up in status and can be cleaned with update --clean.
