The mm_base_modem_grab_port() now receives a MMKernelDevice directly from the plugin, which is then stored in the MMPort corresponding to the port. This means that we have direct access to e.g. all properties set by udev rules everywhere, and we don't need additional GUdevClient objects (e.g. like the one used in the Huawei plugin to detect NDISDUP support during runtime). For virtual ports (e.g. generated during unit tests), we have a new 'generic' kernel device object which just provides the values from the kernel device properties given during its creation.
