Description:
As prepared statements do not support multiple resultsets in order to bind variables and properly call a stored procedure one has to:

- Prepare, bind and execute SET @var=x,@var2=y
- Execute CALL sp(@var,@var2)
- Use general resultset retrieval
- Prepare, execute and fetch SELECT @var,@var2

Ability to use single prepared statement invocation for this sequence would improve usage of MySQL storade procedures. 

How to repeat:
n/a

Suggested fix:
Allow using multiple resultsets for prepared statements or provide additional tree of API calls for efficient usage of stored procedures.

Isn't this implemented by
WL#4435 (Support OUT-parameters in prepared statements)?
