Commit message

Make log API ignore a missing stop commit

Determining whether the stop commit exists in advance requires an extra
round-trip, and clients are likely to just fall back to omitting the
stop commit anyway. start_time and end_time provide an alternative way
to bound the set of commits which can be used in addition to a
possibly-missing stop commit.

Description of the change

This makes it very easily to accidentally request a couple of hundred thousand commits, but I understand the motivation.

Add start_time and end_time parameters to log API

This is useful for bounding the set of commits returned in cases where
we may not have a reliable stop commit.
