Jelena Pjesivac-Grbovic f1aec23507 Adding tuned allgather implementation.

It contains four algorithms: 
Bruck (ciel(logP) steps), Recursive Doubling (log(P) for power-of-2 processes), Ring (P-1 steps),
and Neighbor Exchange (P/2 steps for even number of processes).

All algorithms passed occ, IMB-2.3, and intel verification tests from ompi-tests/ for up to 56 processes.
The fixed decision function is based on results collected over MX on the Grig cluster at 
the University of Tennessee at Knoxville.  
I have also added (and commented out) copy of MPICH2 decision function for allgather
(from their IJHPCA 2005 paper).

This commit was SVN r12910.

attribute

Complete next round of message size reduction: "strip" the descriptive info from the returned values. I have now added a flag to the gpr address mode (ORTE_GPR_STRIPPED) that instructs the gpr to not include segment names or tokens in the returned gpr_value_t objects.
