Added new functions for building device-relative tags. Changed machine

Browse Source 
configuration builder to use these functions. Also changed the laserdisc
player devices to use them. Updated Z80 CTC/SIO code to assume that the
CPU provided for the clock is relative to the device that the CTC/SIO
belong to. Updated memory code to assume that regions and devices
referenced by the memory map are relative to the device the associated
CPU belongs to.
