* Moved the error codes to jerry-port.h and declared port function `jerry_port_fatal`. * Moved "exit or abort on fail" functionality to the newly added jerry-port-default-fatal.c. * This implied that a default port-specific API had to be introduced: functions `jerry_port_default_set_abort_on_fail` and `jerry_port_default_is_abort_on_fail` declared in jerry-port-default.h control the fatal exit behaviour. * For the sake of clarity, renamed jerry-port.c to jerry-port-default-io.c. * Adapted CMakeLists to deal with port implementations consisting of more then one source file and exposing headers. This also required the renaming of `EXTERNAL_PORT_FILE` cmake option to `EXTERNAL_PORT_DIR`. * Adapted main sources to use the default port header for the abort-on-fail functionality, as that is not part of the core jerry API anymore. * Added default port implementation to the static source code checker tools.
