There was an accidental ADI breakage earlier when MPI level codes would
query into the dev part of the MPID request object. This commit removes
that breakage by adding a new macro into the mpiimpl.h file to portably
check whether a request is anysource. For now, in pamid, this macro
always evaluates to 0. This can easily be fixed by overwriting it in the
pamid code, but since pamid doesn't support FT, it won't have any
functional change either.

It was pointed out that by putting this in a macro and failing silently
when unimplemented, this make things challenging for derivatives which
will implement this function in the future. By moving this to an MPID
level function, it becomes more obvious that the function should be
implemented later.

Since pamid doesn't include any of the fault tolerance functions, it
should never say that a message is pending failure. We also can't call
abort in here since the function is usind at the MPI layer.

This function will check to see if a request can be completed if it
involves MPI_ANY_SOURCE. An any source request cannot be completed if
the communicator is not collectively active.

  Added an empty implementation for MPID_Comm_get_all_failed_procs
  and MPID_Comm_revoke in pamid.

Adds function implementing an agreement algorithm for the user. This function
lets the user manually perform an agreement as well as detect unacknowledged
failures.

This commit adds the new functions MPI(X)_COMM_FAILURE_ACK and
MPI(X)_COMM_FAILURE_GET_ACKED. These two functions together allow the user to
get the group of failed processes.

Most of the implementation for this is pushed into the MPID layer since some
systems won't support this (PAMI). The existing function
MPIDI_CH3U_Check_for_failed_procs has been modified to give back the group of
acknowledged failed processes. There is an inefficiency here in that the list
of failed processes is retrieved from PMI and parsed every time the user calls
both failure_ack and get_acked, but this means we don't have to try to cache
the list that comes back from PMI (which could potentially be expensive, but
would have some cost even in the failure-free case).

This commit adds a failed to the MPID_Comm structure. There is now a field
called last_ack_rank. This is a single integer that stores the last
acknowledged failure for this communicator which is used to determine when to
stop parsing when getting back the list of acknowledged failed processes.

Lastly, this commit includes a test to make sure that all of the above works
(test/mpi/ft/failure_ack). This tests that a failure is appropriately included
in the failed group and excluded if the failure was not previously
acknowledged.

A few MPIX functions pertaining to fault tolerance were added to MPICH a while
back. These functions are no longer applicable given the new ULFM
implementation so they are being removed here.

added MPID_Win_allocate_shared and MPID_Win_shared_query support and
fixes on passing incorrect rank to MPIDI_WinCtrlSend in MPIDI_WinPost_post
and MPIDI_WinComplete_post

minor fixes for 'win allocate shared'

- compiles for bgq
- UNRESOLVED: undefined shm key on bgq, or any other time the required
  environment variables are not set
- UNRESOLVED: multiple calls to 'win allocate shared' will use the same
  shm key
