auth: Throttle SQL auth worker process creation if they can't connect to database.

auth: Log a warning if userdb sql isn't used, but user_query or iterate_query isn't default. This is intended to stop people from wondering why user_query doesn't do anything.

auth: If built-in SQL query fails, log it clearly that it was using built-in one.

Moved all storage destruction code to mail-storage.c and made destroy() optional. Removed set_callbacks(). Made autodetect() optional. --HG-- branch : HEAD

Added auth_request_set_credentials() to modify credentials in passdb and implemented it for SQL passdb. Added passdb_need_set_credentials boolean to mechanisms to indicate that it's required (OTP will need it). Patch by Andrey Panin. --HG-- branch : HEAD

deinit, unref, destroy, close, free, etc. functions now take a pointer to their data pointer, and set it to NULL. This makes double-frees less likely to cause security holes. --HG-- branch : HEAD

Don't connect to SQL database in main dovecot-auth process if we're using workers to do it. --HG-- branch : HEAD

Created generic asynchronous SQL API and implemented MySQL and PostgreSQL drivers. MySQL is implemented synchronously because it's API doesn't provide async way to do it. Replaced pgsql and mysql userdb/passdb with generic sql userdb/passdb. --HG-- branch : HEAD
