* term.h (NO_DEVICE): New macro, bit for termflags.
(termflags): Change type to uint_fast32_t.
* devio.c (device_open_reply): For D_NO_SUCH_DEVICE error reply, set
NO_DEVICE flag in termflags.
* users.c (open_hook): If NO_DEVICE flag set, return ENXIO immediately.
If we put out an open request, check for that bit as well as
NO_CARRIER changing in termflags and diagnose with ENXIO.
* Makefile (device_replyServer-CPPFLAGS): New variable, turn off
TypeCheck for this stub. This is necessary for error replies to get
through to our server-side functions in devio.c.
