MFC r268502:

Sync some (mostly cosmetical) changes from NetBSD

Makefile,v 1.37
tc1.c v 1.3
Rename TEST/test.c tc1.c

common.c,v 1.23
pass lint on _LP64.

emacs.c,v 1.22
pass lint on _LP64.

filecomplete.h,v 1.8
mv NetBSD ID back from 1.9 as we don't
have the widecharacter support.

prompt.c,v 1.14
prompt.h,v 1.9
term.h,v 1.20
read.h,v 1.6
Update NetBSD version strings

sys.h,v 1.12
Misc sun stuff.

tty.c 1.31
handle EINTR in the termios operations
Allow a single process to control multiple ttys (for pthreads using _REENTRANT)
using multiple EditLine objects.
pass lint on _LP64.
Don't depend on side effects inside an assert
