a69e1d5f01 Added some error handling to shardrouter. 
The shardrouter now handles situations where the subservice sessions have failed and returns an error if an attempt to
query such a service is made.

a016fdd0b7 Complementary fix to #507, http://bugs.skysql.com/show_bug.cgi?id=507. 
Missing braces in get_route_target made the previous fix ineffective.

readwritesplit.c:get_route_target routed query to slave although query type was combined QUERY_TYPE_READ | QUERY_TYPE_MASTER_READ, where the latter is supposed to be routed to master.

RWSplit router handles query processing errors that happened in router by sending parse error reply to client. routeQuery fails only when backend has failed.

1a76d2d06f Fix to bug #698, http://bugs.mariadb.com/show_bug.cgi?id=698 
debugcmd.c:convert_arg returned zero if argument is invalid. That zero was cast to pointer. Using it caused NULL-pointer references. Changed the return value indicating about error to 0x1 which is then handled properly.

39e4253c81 Fix to bug #694, http://bugs.mariadb.com/show_bug.cgi?id=694 
query_classifier.cc: set_query_type lost previous query type if the new was more restrictive. Problem was that if query is both READ and SESSION_WRITE and configuration parameter use_sql_variables_in=all was set, routing target became ambiguous. Replaced call to set_query_type with simply adding new type to type (=bit field) and checking unsupported combinations in readwritesplit.c:get_route_target. If such a case is met, a detailed error is written to error log in readwritesplit.c. mysql_client.c sees the error code and sends an error to client. Then mysql_client.c calls router's handleError which ensures that there are enough backend servers so that the session can continue.
