Initial import of wdm 1.20 into the NetBSD packages collection as 
x11/wdm.

wdm is a modification of XFree86's xdm package for graphically handling
authentication and system login. Most of xdm has been preserved (XFree86
3.3.2.3) with the Login interface based on a WINGs implementation using Tom
Rothamel's "external greet" interface.
