New global variable route_type with the type of route being executed
This patch adds a new global variable called route_type. This value of the variable is one of the *_ROUTE values defined in route.h. Those defines have been moved from sr_module.h, originally they were used as the flags for functions in module exports but we can use them here for the global route_type variable as well.
The variable route_type is meant to be used by module functions, in some cases they need to test for the type of the route being executed to know what functions are available and whether the sip message being process is stored in shared memory or private memory.
The tm module contained similar variable (which was exported through the tm module API), but it makes more sense to keep it in sip-router core, because the core can execute two route types, the request route and the onreply route, even if the tm module is not used.
