First implementation of G-OMLP.wip-omlp-gedf

This patch implements G-OMLP (OMLP for G-EDF).  It reuses (calls)
much of the code from G-FMLP-Long.  Note that the implementation
here will have to change if/when P-OMLP is implemented.  This is
because P-OMLP uses seperate priority queues (PQ) for each CPU.  The OMLP
code will have to be smarter to figure out when to use a global PQ
or CPU-bound PQ. Also, PQ may be better implemented as a binary
(or binomial) heap.  It is a simple linked-list in this implementation.
