db/simple: mount points
A SimpleDatabase instance can now "mount" other Database instances at certain locations. This is used to use a new SimpleDatabase instance for each storage mount (issued with the "mount" protocol command). Each such instance has its own database file, stored in the directory that is specified with the "cache_directory" option.
