Rework queryString:withEncoding:, and ensure memory is correctly released where used in our overwrites:

 - Check allocated memory and ensure it is released in our code
 - Consolidate code controlling both an initial query and any retries following connection failures
 - Perform additional checking to ensure a connection error was the cause
 - Correctly capture any result sets after the max_allowed_packet setting was changed
 - Check and cache the error strings and numbers for the intended queries, not any helper queries, and return them when requested.
