PAMID: fixes for RMA shared related, lock_all and unlock_all functions

The following has been updated:
- MPID_Win_allocated_shared
- MPID_Win_shared_query
- several functions in mpid_win_lock_all.c, mpid_win_lock.c, mpid_win_free.c and
  structures in mpidi_onesided.h, mpidi_datatypes.h have been modified for
  scalability support for MPID_Win_lock_all() and MPID_Win_unlock_all()

PAMID: fix MPID_Win_allocate_shared, MPID_Win_lock_all/unlock_all and MPID_Win_shared_query

Add changes based on code review feedback from the team:
1) update getPageSize to ensure that the pagesize is obtained from the range of
   passed in address.
2) don't call dispatcher if lockQ[index].done == 1
   if (!lockQ[index].done)
     MPID_PROGRESS_WAIT_WHILE(lockQ[index].done == 0);
3) in mpid_win_shared_query()
   replace
     MPID_assert(win->create_flavor == MPI_WIN_FLAVOR_SHARED);
   by
     MPIU_ERR_CHKANDSTMT((win->create_flavor != MPI_WIN_FLAVOR_SHARED), mpi_errno,
                         MPI_ERR_RMA_FLAVOR, return mpi_errno, "**rmaflavor");
3) some minor fixes.

PAMID: modify MPI_Win_flush_local, MPI_Win_lock etc for better performance

The current implementation for the subject mentioned function is to allocate
two counters for each rank in the window group. The design could cause a scaling
issue.  The fix is to update MPI_Win_flush_local etc with two counters per
window approach.

The changes also include the follwoing:
- provides mutex_lock/mutex_unlock for atomic operations in shared window
- fixes some bugs in handling shared window.
- removes the shared segment with IPC_RMID in MPI_Win_free.

PAMID: fixed base address for each rank in a window group

For shared window, the base address for each rank should not be
exchanged among ranks in a window group. Without the fix, the job
will be terminated with segfault.

Renamed WIN_SEPARATE to WIN_UNIFIED.  pamid's WIN_SYNC already does a
full memory barrier, so we should be all set for UNIFIED support.
