Pageant interface changes. You can now do `pageant -c command' to

spawn another command after starting Pageant. Also, if Pageant is
already running, `pageant keyfile' and `pageant -c command' will do
the Right Thing, that is, add the key to the _first_ Pageant and/or
run a command and then exit. The only time you now get the `Pageant
is already running' error is if you try to start the second copy
with no arguments.
NB the affected files in this checkin are rather wide-ranging
because I renamed the not really SSH1-specific
`ssh1_bignum_bitcount' function to just `bignum_bitcount'.
