19748e6957 fix race condition which can happen on finalize
1. Change in rte api implementation: now comm_world used to do p2p. 
This allows to not worry about other comms being destroyed.

2. added a notification mechanism with a help of which runtime can say libhcoll that RTE api can not be used any longer. 
pass a pointer to a flag, and its size to libhcoll.
The flag changes when the RTE is no longer available. 
Currently this flag is just ompi_mpi_finalized global bool value.

d7a50343bf Per the details and schedule outlined in the attached RFC, Mellanox Technologies would like to CMR the new 'coll/hcoll' component. This component enables Mellanox Technologies' latest HPC middleware offering - 'Hcoll'. 'Hcoll' is a high-performance, standalone collectives library with support for truly asynchronous, non-blocking, hierarchical collectives via hardware offload on supporting Mellanox HCAs (ConnectX-3 and above.) To build the component, libhcoll must first be installed on your system, then you must configure OMPI with the configure flag: '--with-hcoll=/path/to/libhcoll'. Subsequent to installing, you may select the 'coll/hcoll' component at runtime as you would any other coll component, e.g. '-mca coll hcoll,tuned,libnbc'. This has been reviewed by Josh Ladd and should be added to cmr:v1.7:reviewer=jladd
