This patch does several things to termios:

(1) changes all functions to be METH_VARARGS
(2) changes all functions to be able to take a file object as the
    first parameter, as per

http://mail.python.org/pipermail/python-dev/2001-February/012701.html

(3) give better error messages
(4) removes a bunch of comments that just repeat the docstrings
(5) #includes <termio.h> before #including <sys/ioctl.h> so more
    #constants are actually #defined.
(6) a couple of docstring tweaks

I have tested this minimally (i.e. it builds, and
doesn't blow up too embarassingly) on OSF1/alpha and
on one of the sf compile farm's solaris boxes, and
rather more comprehansively on my linux/x86 box.

It still needs to be tested on all the other platforms
we build termios on.


This closes the code portion of SF patch #417081.
