Fix handling of collected results

Browse Source 
The result collection did not reset properly when a non-resultset was
returned for a request. As collected result need to be distinguishable
from single packet responses, a new buffer type was added.

The new buffer type is used by readwritesplit which uses result collection
for preparation of prepared statements.

Moved the current command tracking to the RWBackend class as the command
tracked by the protocol is can change before a response to the executed
command is received.

Removed a false debug assertion in the mxs_mysql_extract_ps_response
function that was triggered when a very large prepared statement response
was processed in multiple parts.
