Don't need to check, it's marked as required
Don't continue to fail spawning connections if we failed once...
Increase max nodes *sigh*
Open query should default to NULL
Check handle is not NULL before dereferencing it CID #1211838
Correct behaviour processing stops in rlm_couchbase (unintended fallthrough)
Fix dereferencing NULL pointer in json_object_object_get_ex
Use consistent config item names in couchbase
Query may be an empty string, too.

We should really fix that in the init function
Tests for list delete
Use pthread ID for more connection debugging.  Helps debug #624
You can only reconnect a handle if it's in-use by you
Tweak reconnect logic.

A reconnect means open new connection, or if that fails, try
to find an unused one.  But don't spawn a new connection.

Also, we can only reconnect a used connection.  It's an error
to reconnect an unused connection.
