log: New functions for replacing a log's contents.
These functions will acquire users in future commits.
This new functionality made the internal state machine of the log hard
enough to understand that I thought that it was best to make it explicit
with a 'state' variable, so this commit introduces one.
This commit duplicates code and logic from ovsdb_rename() and
ovsdb_compact() in ovsdb/file.c. A future commit removes this duplication.
