[Simh] porting simh to plan9

[Fernan Bolando]

after some debugging, I finally know what is causing simh to become
non responsive.
the good news is simh25 can easily be compiled through plan9 ape
compatibility. The bad news is poll_kbd is blocking in plan9 so it
does not return untill you press crriage return. commenting out
poll_kbd allows the pdp11 to boot and show it's prompt but you will
not be able to send keyboard command. it also crashes a few seconds
after that so after fixing the nonblocking problem something might be
broken

so i need a plan9 version of poll_keyoard or get telnet approach working.
