MINOR: applet: Add HTX versions for applet_input_data() and applet_output_room()

It will be useful for HTX applets because availale data in the input buffer and
available space in the output buffer are computed from the HTX message and not
the buffer itself. So now, applet_htx_input_data() and applet_htx_output_room()
functions can be used.
