* RO/collectives: add linear algorithms using RPut/Rget
- make broadcast, alltoall and fcollect use a simple linear algorithm
using MPI_RPut/Rget, but without blocking in the execution
- remove the to_all interfaces, since they have been deprecated.
- remove the active-set interfaces, since they have been removed from
rocSHMEM
* avoid notification after barrier

* disable allocation of ata_buffer
a temporary buffer of 128MB was allocated when creating a team. In
previous versions of the code, that buffer was used by some collective
operations. This is not the case for now. Therefore, do not allocate the
buffer for now. I am not removing the element itself from teh
structure, since we might need it in future versions again.
