Log message:
Import libXmu-1.0.2 from pkgsrc-wip:
This Xmu library contains miscellaneous utilities and is not part of the
Xlib standard.  It contains routines which only use public interfaces
so that it may be layered on top of any proprietary implementation of
Xlib or Xt.

This also includes the Mini Xmu library that does not use Xt and Xaw.

This is part of the X Libraries and Protocol Headers Project at
freedesktop.org.
