Add support for more levels of global locks.

The old ddl_lock was replaced by ddl_lock and write_lock.
The ddl_lock now only locks database against concurrent DDL but not
against writes anymore. The write_lock locks against writes the same way
old ddl_lock used to. We support upgrading the ddl_lock to write_lock at
some performance penalty (the lock needs to be negotiated again).
