2. fix a bug in the initial communicator creation of llcomm
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.

Possibly fixes CID 417
* ensure to initialize inner members upon default constructors using
the same syntax across all classes
* remove some member variables that aren't used anymore
* "initialize" the inner MPI_Status in the default constructor for
MPI::Status by calling the default constructor mpi_status(). This
may or may not silence CID 417; we'll see what happens in
subsequent Coverity Prevent runs.

* 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.
This commit was SVN r19219.
* use "warn_on_fork" instead of "do_not_warn_on_fork" -- i.e.,
use positive logic instead of negative logic
* ensure that pthread_atfork() is only called once
* amended the error message to include the hostname, PID, and
MPI_COMM_WORLD rank of the offender
* ensure that the warn_fork_cb() function is only defined if
HAVE_PTHREAD_H so that we don't get a compiler warning if it isn't
used

This is setup so that it only is issued once (as opposed to every time they do it), and goes through orte_show_help so the user doesn't get hammered by #procs copies of the warning. In addition, there is a new MCA param (can't have too many!) to shut the warning off altogether.
This closes ticket #1244

(it is just set within MCA_PML_OB1_RECV_REQUEST_UNPACK)
Iff Coverity's prevent makes usage of __attribute__(unused),
this should get rid of warning.
Relates to CID1060
Would then apply to a many int _rc; definitions, that are
used in other macros in similar fashion...

Revise the scope precedence in the MPI_Publish, Unpublish, and Lookup functions. If a global server was specified and is available, then default to using it for all three functions. If not, then default to using local scope.
If an info_key was provided, then it takes preference. We always follow the user's direction - this change only impacts the scope ordering if the user -doesn't- tell us the order to use.
This commit was SVN r19146.
The optimization that was introduced a year ago for saving a collective
synchronization step for certain communicator creation functions has to be
disabled for now. The bug has been exposed by the hierarch module, but could
appear as well for inter-communicator creations. The problem is, that within a
communicator creation step we invoke a comm_dup (for intercomm_create) or
other collective operations (in case of hierarch) before all processes have
been synchronized. This lead to the "Dropped message for non-existant
communicators" error. This commit disables the optimization without removing
it from the code base. In theory, it can be enabled again as soon as we have
the unexpected message queues for unknown cid's, which were required if I
remember right anyway for the multi-threaded scenarios and potentially for
fault tolerance.
Before moving the patch to 1.3 I would like to let it soak for a couple of
days on trunk. Please note, taht my 2nd comment on ticket #1408 was
semi-correct, since the order of activation of the communicator and quering
the collective module have already been changed earlier.
