wip/xrdp 0.5.0 NetBSD

Based on the work of rdesktop, xrdp uses the remote desktop protocol to present a GUI to the user. The goal of this project is to provide a fully functional Linux terminal server, capable of accepting connections from rdesktop and Microsoft's own terminal server / remote desktop clients. Unlike Windows NT/2000/2003 server, xrdp will not display a Windows desktop but an X window desktop to the user. Currently, xrdp uses Xvnc to manage the X session.
