* All external programs and scripts are now called by execve() on unix and
CreateProcess on Windows.
* The system() function is no longer used.
* Argument lists for external programs and scripts are now built by the new
argv_printf function which natively outputs to string arrays (i.e.
char *argv[] lists), never truncates its output, and eliminates the security
issues inherent in formatting and parsing command lines, and dealing with
argument quoting.
* The --script-security directive has been added to offer policy controls on
OpenVPN's execution of external programs and scripts.
Also added a new plugin example (openvpn/plugin/examples/log.c) that logs
information to stdout for every plugin method called by OpenVPN.

and then fails over to 'netsh' if the DHCP negotiation fails.
* Made --ip-win32 adaptive the default.
