adamdunkels 1a13d25d33 Revised version of the X-MAC implementation that uses a ctimer instead
of an rtimer for the periodic radio duty cycling. The benefit of this
implementation is that it leaves an rtimer free for user tasks. The
drawback is a slightly higher idle power consumption. This new version
is based on the current rtimer-based X-MAC.
