Completely revamped the system for calling external programs and scripts:
* 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. git-svn-id: http://svn.openvpn.net/projects/openvpn/branches/BETA21/openvpn@3122 e7ae566f-a301-0410-adde-c780ea21d3b5
