Support per-partition timestamps
update_engine is heading toward supporting partial updates, which an OTA
update can update just a subset of all partitions. In this context, a
single max_timestamp in OTA manifest is insufficient for checking
potential downgrades, as different partitions can have different
timestamps. This CL adds per-partition timestamp support on
update_engine side. update_engine will accept a payload with
per-partition timestamps and reject the update if any partition has an
older timestamp.
Changes made:
1. Add new version field to PartitionUpdate protobuf message.
2. Add new methods to HardwareInterface for fetching/checking
timestamp of each partition.
3. Update delta_performer to invoke new APIs in 2 properly.
4. Add relevant testcases.
Test: unittest
