config.c: Added configuration parameter processing for read_ses_variables_from_slaves and for write_ses_variables_to_all . The values are read from config file, qualified and stored to service. Values are loaded when instance is created. This is limitation in current implementation and will change so that configuration is dynamically changeable.
server/modules/filter/Makefile: Fixed problem which prevented cleaning and compiling hintfilter library.
server/core/config.c: Removed unused if..else block from config_get_valint. Changed it also to return value which indicates whether the operation succeed. Added config_get_valbool similar to config_get_valint.
service.c:Added typelib-like struct and array of valid boolean values. Fixed parameter type test in service_set_param_value. Completed boolean type parameter handling.
hintparser.c:Fixed error message for non-maxscale hints.
readwritesplit.c:Added loading of configuration parameters from service to instance and from instance to each new session. Fixed routing condition in get_route_target. Modified get_route_target so that it takes also rw_read_sesvars_from_slaves and rw_write_sesvars_to_all as parameters.
skygw_types.h: added array size counting macro.
readwritesplit.c:Fixed macro which excludes a block from compiled code.
