Description

• Increase log entry's index field to 32 bits.
• In newtmgr read log command, the index is the only criterion for selecting the start point of the read (don't use timestamp anymore).
• On startup, read the last entry from each flash log to determine the index of the next entry. This is to ensure the next entry written has the correct sequence number.
