Module dir is no longer mandatory, add 66 configuration variable on the envrionment at call of the configure script, merge configuration files for services inside the module, less redundant code,fix search of instantiated services source, implement all dependencies of service recursively, fix environment parse process

add overwrite_conf at sv_alltype_s struct,add uint8_t disable_module argument to parse_service_before, add uint8_t conf argument at parse_add_service and regex_configure,change to the new return of read_svfile. Only disable the main module, overwrite configuration file for service inside a module

crash on system failure not on empty environment, also this is valuable for the 66-boot (wrong previous commit) change
