server/modules/filter/Makefile: Added path to libmysqld (-L<path>) so that linker finds it at compile time.
server/test/MaxScale_template.cnf: added write_ses_variables_to_all=Yes and read_ses_variables_from_slaves=Yes so that tests included in testall target succeed (at server/modules/routing/readwritesplit/test). Added hint filter to 'normal' rwsplit service.
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.
Fix to #473, http://bugs.skysql.com/show_bug.cgi?id=473
Several memory issues. Read the code.
In general one-off hint is only added to gwbuf and freed in gwbuf_free. Stacked hint is copied to stack and to gwbuf. gwbuf is freed after routing but stacked hint is freed either in stop or when session is closed. All this applies to named hint as well except that in addition, it has one more copy in named hint struct which is emptied when session is closed.
hintparser.c:hint_parser:when string token is found, create a copy of the token value instead of copying the its address because token will be freed before the value is used.
hint_next_token:didn't recognize '=' as TOK_EQUAL, fixed that. Read the code.
hint.c:hint_create_parameter: copy the pointer to parameter name instead of creating copy of it - pname is already copied from token before the call
readwritesplit.c:routeQuery:Hint name was copied when hint value was supposed to be copied, thus resulting invalid value for hinted parameter. Also fixed server type in trace log command.
skygw_debug.h:Added string for Relay server to macro STRSRVSTATUS.
session.c:session_setup_filters : fixed memory leak
hintparser.c: added token_free for HINT_TOKENs and fixed a few memory leaks.
mysql_client_server_protocol.h: added mysql_protocol_done which frees memory blocks pointed to by protocol members. Those can't be freed in dcb.c because dcb.c doesn't know about protocol's members.
mysql_backend.c:gw_backend_close: fixed memory leak
mysql_client.c: gw_client_close: fixed memory leak
mysql_common.c: added implementation of mysql_protocol_done
:protocol_archive_srv_command: tried to fix memory leak. Some memory is still leaking according to valgrind. Removed use of uninitialized local variable len.
readwritesplit.c: Fix to bug #469, http://bugs.skysql.com/show_bug.cgi?id=469, rwsplit counts every connection twice in master - counnection counts leak
execute_sescmd_in_backend: fixed a memory leak - visible only in DEBUG=Y build.
readwritesplit/test/makefile: added target for hints tests
