Title: Prevent variable_init from retuning an empty array.

Patch does a couple of things

* If the recursion_depth hit the limit, assume we aren't going to get it from the cache or the lock will be released any time soon. Give up and get variables from the database.
* If the db result is FALSE run _db_error_page(). This prevents the cache from getting polluted with bad (empty) data.
* Various white space fixes.
