This commit also fixes a bug in ompi_comm_idup where the newcomm was not
set until after the operation completed.

MPI_Comm_idup.
As part of this work I implemented a basic request scheduler in
ompi/comm/comm_request.c. This scheduler might be useful for more
than just communicator requests and could be moved to ompi/request
if there is a demand. Otherwise I will leave it where it is.
Added a non-blocking version of ompi_comm_set to support ompi_comm_idup.
The call makes a recursive call to comm_dup and a non-blocking version
was needed. To simplify the code the blocking version calls the nonblocking
version and waits on the resulting request if one exists.

The algorithms are intended for MPI-3.0 compliance and are not
optimized. We should aim to add better algorithms in the future through
cheetah.
MPI_Iallreduce and MPI_Igatherv on intercommunicators are required for
MPI_Comm_idup support.

1. Change in rte api implementation: now comm_world used to do p2p.
This allows to not worry about other comms being destroyed.
2. added a notification mechanism with a help of which runtime can say libhcoll that RTE api can not be used any longer.

The flag changes when the RTE is no longer available.
Currently this flag is just ompi_mpi_finalized global bool value.

- adapted Open MPI version check (the "const" stuff will come with version 1.7.4, not from 1.9.0)
- removed the const keyword from the deprecated functions MPI_Type_hindexed and MPI_Type_struct
TODO: Since MPICH v3.x adds the const keyword to that functions we need a configure test to figure out whether adding const is required. (only relevant for the stand-alone version of VampirTrace)

Use proper array types for the sendtypes and recevtypes params in the
definition of these subroutines (since they're prototyped to be array
parameters in the module). See the comment in the code for a more
complete explanation.
Note that after talking to Craig Rasumussen, he says that this is
fairly common practice in the Fortran community (i.e., pass a scalar
that is part of an array to effectively pass an offset into that
array, since Fortran passes by reference). So this might be a hack,
but it's a commonly-accepted hack.

This commit was SVN r29298.
* Always enable "const" in the wrapper functions, even though Open MPI
doesn't advertise itself as MPI-3.0 yet
* Remove CONST from MPI_Type_hindexed, MPI_Type_struct (because
they're deprecated functions, and never had const added to them)

collective to the mca_coll_base_comm_coll_t structure increased the size

This fix is a temporary fix to allow the trunk to compile. Unfortuantely
it breaks the compatibility with all other versions of Open MPI. Please

Create a new required key in the OMPI layer for retrieving a "node id" from the database. ALL RTE'S MUST DEFINE THIS KEY. This allows us to compute locality in the MPI layer, which is necessary when we do things like intercomm_create.

The MPI 3.0 standard added const to all in buffers in the C bindings. This

Prevent frag from being freed out from under us in the case
the PML callback routine calls usnic_free(). We accomplish this
by delaying decrement of sf_bytes_to_ack until after the callback is
performed, since sf_bytes_to_ack == 0 is condition of freeing the frag.

Includes all MPI functions supported by Open MPI, including MPI-3
functions (as of about 2 weeks ago). Many changes compared to the
prior generation of Java bindings; not much is left from the prior
generation, actually. The changes include (but are not limited to):
* Add support for more than just a subset of MPI-1 functions
* Use typical Java case for symbol names
* Support Java Direct buffers (giving darn-near "native C"
performance)
* Support "type struct" better than the prior generation
* Make more of an effort for the Java bindings to be a thin layer
over the back-end C bindings
* ...and more
A proper README with more information about what is supported, how to
use these bindings, etc. will be committed shortly.
