get window size via ioctl

Reorder include files now that ioctl.h needs sys/types.h.
Simulate "crt" style erase and kill if the local mode says to.

don't call setbuf; make termcap buffer static.

changed -d messages, fixed prompt glitch, underline glitch (tvi's), shell stdin, execute() bugs

Wait until we're foreground before saving the terminal modes. Use
the fileno() macro throughout.

make ^D scroll 1/2 screenful by default.

ignore SIGTTOU while resetting on TSTP (else can stop before reset

make it use termcap again ...
leave terminal mode on exit as we found it on entry.

no more local/uparm.h
