scmutil: extend termwidth() to return terminal height, renamed to termsize()

It appears crecord.py has its own termsize() function. I want to get rid of it.

The fallback height is chosen from the default of cmd.exe on Windows, and
VT100 on Unix.

# showstack.py - extension to dump a Python stack trace on signal
#
# binds to both SIGQUIT (Ctrl-\) and SIGINFO (Ctrl-T on BSDs)

def sigshow(*args):
    sys.stderr.write("\n")
    traceback.print_stack(args[1], limit=10, file=sys.stderr)
    sys.stderr.write("----\n")

    signal.signal(signal.SIGQUIT, sigshow)
    try:
        signal.signal(signal.SIGINFO, sigshow)
