Here we wrap up common action when one RMA op is finished on target
into a function to make code structure cleaner.

Originally do_accumulate_op() only accepts request pointer as
argument which is too restrict to be reused. Here we modify
it to access buffer address, count, datatype and op, so that
it can be reused in more general cases.

When operation pending list and request lists are all empty, FLUSH message
needs to be sent by origin only when origin issued PUT/ACC operations since
the last synchronization calls, otherwise origin does not need to issue FLUSH
at all and does not need to wait for FLUSH ACK message.

Similiarly, origin waits for ACK of UNLOCK message only when origin issued
PUT/ACC operations since the last synchronization calls. However, UNLOCK
message always needs to be sent out because origin needs to unlock the
target process. This patch avoids issuing unnecessary
FLUSH / FLUSH ACK / UNLOCK ACK messages.

Stack variables should not have been used as sendbuf for MPI_Iallgather
because we do not wait the completion of MPI_Iallgather in caller
functions. This fix moved them to the struct used for keeping track
of operation state and uses variables in the struct for MPI_Iallgather.

Nightly testing reported timeout on octopus with 12 timelimit. Each of
them took 12:05 ~ 12:10 mins.

This tests the behavior after a failure when using revoke+shrink. Right
now this test still fails so it is marked as xfail.

Ported test programs using collective I/O in the ROMIO test directory
to the nonblocking collective I/O version. They were temporarily added
to the MPICH test directory to run with Jenkins and nightly tests.
However, they may need to be moved to the ROMIO test directory later.

This patch implemented four functions for nonblocking collective I/O,
which will be added to MPI 3.1 standard. Details for these functions
can be found in the MPI-Forum ticket,
https://svn.mpi-forum.org/trac/mpi-forum-web/ticket/273

.
Currently, they are implemented as MPIX functions.

Some of the FT tests were not correctly setting their error handlers to
MPI_ERRORS_RETURN. While this doesn't seem to have caused problems, it's
safer to do so.

This commit also cleans up some unused variables, reorders communicator
creation, and correctly frees some variables to avoid some debugging
output.

Depending on how some uninitialized data was prepopulated, the ibsend
check was periodically crashing out in the call to
MPID_Request_is_pending_failure. Some simple sanity checking to make
sure the input data wasn't NULL takes care of this.

The previous code only detected a datatype mismatch when the message
was copied out of the unexpected queue. Now it will throw an error
in both cases.

We also set the error in the status object to match the default ch3
behavior. This fixed an issue where the request would not be freed
and cause extra debugging output at MPI_Finalize.

MPID_Send should first check the state of a VC to see if it is valid
before creating a group, request or communicator.

In the case of fault tolerance, if VC has already been revoked or marked
as terminated (e.g., in test/mpi/ft/senddead). The send operation
evolved should exit without creating any memory objects of request,
group or communicator.

The MPI collectives get and set the errflag used by the collective
helper functions (MPIC_*). The possible values of the errflag changed,
so the collective functions need to appropriately set this value using
either MPIR_ERR_NONE (MPI_SUCCESS), MPIR_ERR_PROC_FAILED
(MPIX_ERR_PROC_FAILED), or MPIR_ERR_OTHER (MPI_ERR_OTHER).

This should allow collectives to correctly report process failures when
they occur now, fixing the FT tests that use collectives (see #1945).
Signed-off-by: Huiwei Lu <huiweilu@mcs.anl.gov>

The errflag value being used in the MPIC helper functions only
propagated whether or not an error occurred. It did not contain any
information about what kind of error occurred, which made returning the
correct error code after a process failure impossible.

This patch converts the binary value to an enum with three options:
MPIR_ERR_NONE
MPIR_ERR_PROC_FAILED
MPIR_ERR_OTHER

The original use of TRUE and false maps to MPIR_ERR_NONE and
MPIR_ERR_OTHER.

MPIR_ERR_PROC_FAILED indicates that the error occurred
because of a process failure. It uses the new bit set aside from the tag
space to track such information between processes.

This change required modifying lots of function signatures and type
declarations to use the new enum type, but these are actually not very
intrusive changes and shouldn't be a problem going forward.

We need to take another bit from the tag space to specify the difference
between a generic failure and a process failure. This patch modifies the
