_mysql: Move type converter initialization outside of module. When opening

the connection, a mapping of MySQL types to Python functions may be passed
as the keyword argument conv. This is stored as the converter attribute
on the connection object, and may be modified, assigned, etc.

MySQLdb: Build full converter dictionary, pass along to _mysql when
creating a connection.

MySQL_doc: Fixed a minor documentation bug.
