Integrate //core into existing code base
This disables a few tests which are broken still: - tests/error_004_missing_module.test - tests/error_005_missing_dynamic_import.test - tests/error_006_import_ext_failure.test - repl_test test_set_timeout - repl_test test_async_op - repl_test test_set_timeout_interlaced - all of permission_prompt_test
