  use db_lock_table() and db_unlock_tables() for your code to be compatible.

- Patch #29274 by Jeremy: the "fuzzy cache" mechanism is supposed to enforce a minimum time before the cache table is flushed. Logical errors in the fuzzy cache implementation are leading to the cache table being flushed more frequently.  Configuration is simplified by removing all references to "strict" and "loose" caches. Instead, the cache is either "disabled" or "enabled". Additionally, the site administrator can now configure the "minimum cache lifetime", the minimum amount of time cached data will remain cached.
