by window callback functions so that keyboard input *only* goes to the
top window.
NOTE: nxterm_kdbin() is an internal OS API. It can be accessed by
applications via the boardctl(BOARDIOC_NXTERM) interface.
The logic path is complex in this case: (1) The keyboard input is
received by an application listener thread and injected into NX via
nx_kbdin(). NX sends (2) the keyboard input to single the NX window
that has focus. That window then (3) gives the keyboard input to the
single NxTerm associated with the window via boardctl(BOARDIOC_NXTERM).
NOTE: If CONFIG_NXTERM_NXKBDIN not defined, then NxTerm input coming
directly from /dev/console. That works well if there is only a single
NxTerm window. But if there are multiple NxTerm windows, then it is
anyone's guess which will receive the keyboard input. That does not
work well in such cases.
