1. remove direct routed module (hooray!)
2. add radix tree routed module (binomial remains default)
3. remove duplicate data storage - orteds were storing nidmap and pidmap data in odls, everyone else in ess
4. add ess APIs to update nidmap, add new pidmap - used only by orteds for MPI-2 support
5. modify code to eliminate multiple calls to orte_routed.update_route that recreated info already in ess pidmap. Add ess API to lookup that info instead. Modify routed modules to utilize that capability
6. setup new ability to shutdown orteds without sending back an "ack" message to mpirun - not utilized yet, will require some changes to plm terminate_orteds functions in managed environments (coming soon)
Initial tests indicating that fully routing comm via defined routing trees may not actually have a significant cost for operations like IB QP setup. More tests required to confirm.
This will require an autogen...

Without this patch, doing spawn in a loop ended up by exhausting all
available file descriptors pretty quickly. There were about 5 file
descriptors opened per spawned process. Now the number of file
descriptors managed by the process (orted or HNP)
is a lot smaller.

Moreover, I could not figure out why <time.h> would need to be
included twice. So, I substituted the former for the latter,
in the superfluous instantiation.

<infiniband/driver.h> cannot be included because it will fail to
compile. So per advice from Roland, in that case, just put manually
include the one ibv_*() prototype that we need. Use an undocumented
feature of AC_CHECK_HEADERS to check for <infiniband/driver.h> that I
was told on the autoconf mailing list (see the comment for more
details).

We were only allocating one whereas we would typically need
one per interface. Most of the time we got lucky and we
happily trundled over unallocated memory. But with enough
interfaces, we would get a SEGV.
Also add include to fix compilation with static libs.

THREAD_MULTIPLE. There's a new (hidden) MCA parameter to re-enable
these BTLs in the presence of THREAD_MULTIPLE:
btl_base_thread_multiple_override. This MCA parameter should ''only''
be used by developers who are working on make their BTLs thread safe;
it should ''not'' be used by end-users!

I copied the config directory in another location, and the original
.svn directory was replaced by the Open MPI one ... As a result my
first commit, applied the changes on the Open MPI trunk instead of
the other project.

would not build. These new files will force the build process to look
up the value of "logical true", instead of arbitrarily setting a value,
enabling compatibility between GNU and PGI compilers.

(this was missed in #1585). Also, fix a long-standing problem that
the F90 wrapper compilers were using the F77 wrapper compiler flags.

Update the make_dist_tarball script to check for the proper GNU tool

Modify read_write test to allow specification of rank to read stdin.
IOF now validated to work for arbitrary rank as stdin target. Not validate to work for multiple simultaneous ranks reading stdin (untested).

1. remove some stale files that were overlooked in original commit
2. add a test program and data to stress iof for stdin
3. cleanup a debug statement that caused memory corruption when reading large files
4. some minor cleanups to correctly handle xon/xoff scenarios

We had a public symbol named "already_opened". This commit changes
the name to mca_btl_base_already_opened.
I guess it's good we have the visibility stuff enabled by default!

1. Allow MX bonding via btl_mx_bonding MCA parameter. With this on, Open MPI
suppose that lib MX will do the bonding, and we will only return one BTL.
Otherwise, we return as many as devices.
2. Decrease the memory footprint, by cleaning up what we store about the
peers and how we store it.
3. Allow multiple MX routes that share the same mapper. In this particular
case we will link by their nic_id.
4. Allow multiple MX routes with multiple mappers. In this case we match
the NICs based on the last 6 digits of the mapper MAC.
5. Increase the size of the eager and rendez-vous eager limits in the
case where we are unable to register an unexpected callback with MX.
6. Increase the default max number of MX fragments.
7. Increase the max number of MX BTLs.
8. Only allow mx_if_include and mx_if_exclude if we have acess to the
mapper.

compilers as well. Not doing this was causing problems with
MPI::ERRORS_THROW_EXCEPTIONS with gcc in 32 bit (but not 64 bit!).
* Ensure that the C and Fortran compilers actually like the C++
exceptions flags. If not, currently just abort. Let's see if
anyone complains about this -- I doubt they will because a) C++
exception support is not enabled by default, and b) I think C++
exceptions really only make sense within the same compiler family.
