[pptp-server] prototypes...

[Peter Galbavy]

This is unlikely to make any *real* difference, but I noticed that a
number of prototypes are declared in the .c files under the comment
/* local function prototypes */.

To allow the compiler to be our friend, I am goind to do a couple of
things this morning;

1. Make *all* "local" functions static

2. Depending on the results of this (I can only check the OpenBSD
compile at this time) I will move prototypes into .h files as
appropriate.

(Just notices that launch_ppp() was declared but never defined or used
in pptpmanager.c - legacy I guess, but still...)
