(related to the presence of posix threads and ptmalloc2) is now a
little outdated: since we don't build ptmalloc2 as part of libopal
anymore, the openib BTL's requirements are not directly tied to
ptmalloc2's anymore. Specifically, I altered the test to:
1. At compile time, if no threads are found, the ptmalloc2 component
is going to be built, '''and the ptmalloc2 component is going to be
inside libopal,''' then refuse to build the openib BTL.
1. At run time, if no threads were available at compile time and the
ptmalloc2 component is part of the process, then refuse to use the
openib BTL.

figure it out at runtime (really meaning: we'll still default to "0"
unless something explicitly overrides to 1, such as the openib BTL).
This way, ompi_info doesn't confusingly report mpi_leave_pinned==0 for
mpi_leave_pinned, but we end up running with mpi_leave_pinned==1.

remove the unconditional opal_output's when mmap() fails, and instead,
conditionally output the failure message via btl_base_verbose settings.

The new component fixes a number of problems with the old component. The core algorithm is the same, but by changing the data strucutres a bit we have improved performance and memory utilization.
There are still a couple corner cases that still need some work. However, I did not want to delay bringing this into the trunk (and v1.3 branch) for too much longer.

checking for contiguous datatypes by using our native DDT engine
(rather than several MPI_* calls). The majority of the work is in the
IO ROMIO module.c file, but there's a small part in
adio/common/iscontig.c that we're also submitting upstream.

mostly don't use this mechanism, as we have to be thread safe in order to
really take full advantage of it. The unexpected handler is called by one
of th MX threads, and we do not have control on the moment. In a non threaded
case, this will completely destroy our recv requests queues, so the safest
approach is to don't the unexpected handler.

Don't modify coords in the top-level API function because coords is an
IN variable. Instead, as Nysal noted, the real cause of the problem
was a missing ! down in topo_base_cart_rank.c. Put a comment down in
topo_base_cart_rank.c explaining what's going on so that the code is
not so cryptic.

* Various changes to enable 0-dimensional cartesian communicators:
* Set various mtc_* members to NULL when there are 0 dimensions (and
don't bother trying to memcpy these arrays when duplicating the
communicator -- because they're NULL)
* adjust topo_base_cart_sub to correctly handle 0 dimensions
(simplified it a bit)
* adjust a few error codes to return ERR_OUT_OF_RESOURCE
* adjust error checking of CART_CREATE, CART_RANK
* Allow MPI_GRAPH_CREATE to accept 0 == nnodes.
* Bump reported MPI version in mpi.h to 2.1

guarantee local progress, my opinion is we don't need to do anything
special for complete sends. Perhaps I'm wrong on that one, in which
case this implementation of send_complete is not quite right.
* Give a slightly better error message when a catchall is hit, so that
we can at least know *which* catchall is hit.

3. fix a bug which showed up as the result of fixing issue number 2: we have
to check now whether llcomm has really be created before freeing the
according llcomm in hierarch_destruct.

generate an overlap between the different layers. Why four versions? Because
there is right now always the trade-off between using non-blocking operations
on a layer with a trivial, linear algorithm and using the more sophisticaed
algorithms in a blocking manner.
- bcast_intra_seg used the bcast of lcomm and llcomm, similarly
to original algorithm in hierarch. However, it can segment
the message, such that we might get an overlap between the two
layers. This overlap is based on the assumption, that a process
might be done early with a bcast and can start the next one.
- bcast_intra_seg1: replaces the llcomm->bcast by isend/irecvs
to increase the overlap, keeps the lcomm->bcast however
- bcast_intra_seg2: replaced lcomm->bcast by isend/irecvs
to increase the overlap, keeps however llcomm->bcast
- bcast_intra_seg3: replaced both lcomm->bcast and llcomm->bcast
by isend/irecvs
The code is lightly tested, more testing to follow right now.

Roland noticed that the QLogic HCA driver was using the PCIe vendor ID
for the ibv_query_device so the IEEE OUI value is now used. This means
the config file should recognize the vendor ID value 0x1175 too.

* Make the creation of the build dir for the man pages a bit more
robust (thanks to suggestions from Ralf W.).
* Only distribute the .Xin files, not the .X man pages themselves.
* Make the .X files depend on opal_config.h so that if you re-run
configure and change opal_config.h (e.g., a new version), the man
pages should get rebuilt.
* Man pages are now cleaned with "distclean", not "maintainer-clean".
* Fix a typo in opal_crs.7in.
* Udpate make_dist_tarball to update "date" in the VERSION file.
* Make make_dist_tarball a bit friendlier to hg checkouts.
