* add team-barrier implementation
add a team-barrier API and implementation in the IPC and RO conduit.
Clean up some of the logic in the RO Conduit to distinguish between
sync, sync_all, barrier, and barrier_all.
* add team_barrier_tests to functional tests
* 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.

- Remove hdp and ipc pointers from BlockHandle, align RO stats with RO contexts
- Add run commands for `rocshmem_g` and `rocshmem_p` API tests in driver.sh
- Allocate rocshmem API return buffers based on number of device contexts.
- Associate status flag address with blocking calls and remove threadId dependency
- Associated the status flag address with each blocking call request to notify the GPU thread.
- Removed dependency on threadId for determining the appropriate status flag index.
- Move status flag buffer allocation to backend.
- Initialize allocated memeory to zero
