Bug 462, http://bugs.skysql.com/show_bug.cgi?id=462, fixed path MAXSCALE_HOME path expression in server/test/makefile
Added check for session state before calling router->closeSession
branch release-1.0beta update
Bug #468, http://bugs.skysql.com/show_bug.cgi?id=468, Query classifier accessed freed thread context. If parsing fails thd doesn't need to be freed because it holds correct information about command type.

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:execute_sescmd_in_backend: fixed a memory leak - visible only in DEBUG=Y build.
Fix to http://bugs.skysql.com/show_bug.cgi?id=469, connection counter leaks in master.
Removed redundant counter increments.
Partial fix to #463, http://bugs.skysql.com/show_bug.cgi?id=463
log_manager.cc: fixed block buffer overflow. Queries are logged to trace log and long queries exceed the bufsize in length. Those were written beyond allocated memory areas.
mysql_client_server_protocol.h: added mysql_protocol_state_t to indicate whether MySQL protocol object is allocated, usable or freed. Freed means that memory allocations made by the protocol are freed. That is, command history etc.
mysql_backend.c: gw_backend_hangup and gw_error_backend_event used to call error handling function although session was already closing. Added check for session state.
mysql_client.c: route_by_statement lost some packets in case where query was sent in multiple packets.
mysql_common.c: gw_MySQL_get_next_packet failed in packet handling with route_by_statement. When multi-packet query was merged into one, packet type wasn't copied.
	protocol_archive_srv_command and mysql_protocol_done didn't have proper locking in place which lead to occasional crashes.

rwsplit router tests for session variables
mysql_client.c:gw_error_client_event & gw_client_hangup_event: added session state check, if session is already closing, don't start redundant call to dcb_close.
mysql_common.c:mysql_protocol_done: added protocol state check. Used not to check it which caused double free of allocated memory.
Merge branch 'release-1.0beta' of https://github.com/skysql/MaxScale into release-1.0beta
mysql_common.c:protocol_add_srv_command didn't check that protocol status was MYSQL_PROTOCOL_ACTIVE and wrote to freed memory.
Fix to bug #463, http://bugs.skysql.com/show_bug.cgi?id=463
mysql_common.c:gw_MySQL_get_next_packet didn't handle case where an insert command followed by alter table in the same read buffer. It shouldn't been possible without multi-statement being set.
