Add collectable resultset buffer type

Browse Source 
The new type allows routers to send queries and get complete result sets
as a response. This allows the routers to easily send commands that create
result sets and which are parsed by the router.

Currently only the schemarouter benefits from this new capability as it
generates the database mappings by parsing the output of a SHOW DATABASES
query.
