conflict with the other declarations in other files. tputs() is
traditionally declared to return int, not void. curses.h has it as int.
ncurses has int and actually sets the return value. This problem has
been causing the ircII port to not compile.
(I've only minimally tested this, I do not have libtermcap on my systems)
variable directly in tgetent by stderr or stdout output speed.
It helps hide in non-standard __set_ospeed function and remove it
from other sources (coming soon).
Do prototype cleanup too.
Basically all termios+termcap pgms needs it.
It set ospeed variable using nearest-matched stty speeds,
which helps termcap pgms works with non-fixed termios speeds
and not duplicate ospeed switch into every pgm.
Also it isn't standard function, its source code is too big to include it
in whole to every termcap+termios pgm.
