4.4BSD snapshot (revision 8.1); add 1993 to copyright

trailing comment after #else or #endif

make kernel includes standard

checkpoint almost working version of kernel TP0/X.25; TP4/Cons seems
to crash system still.

this version works somewhat in making outgoing calls.

coding of call{ed,ing} addr extension facil is wrong;
if cons_use_facils is off leave early to avoid non-defined pointers.

new copyright; att/bsd/shared

forgot to set callback in cons_connect;
make cons_tpinput smart about call accepted and disconnection.

NSAP to X.121 address translation didn't look at nsap length.

Checkpoint integration of tp_cons with UBC X.25; compiles only;
not tested, probably not complete.

tsleep changes (checked in by sklower)

../h => (implicitly) ../sys

Checkpoint as of first successful tp connection, before posix, &
before mckusick starts incorporating gnodes
