* Update exactly how we handle MPI exceptions, particularly with
respect to MPI-1 section 3.2.5, and how error handlers are only
invoked for the ''first'' request that generates an exception.
* Update the "see also" section to be consistent across all 8
MPI_Test* and MPI_Wait* functions.
* Fixes trac:560

adding new procs that the remote proc's pml is the same as our local pml.
Turns the hangs from mismatched PMLs into an abort, which is better,
I think.
This commit was SVN r13582.
Adjust the RMAPS mapped_node object to propagate the required launch_id info now included in the ras_node object. This provides support for those few systems that don't use nodename to launch, but instead want some id (typically an index into the array of allocated nodes). This value gets set for each node in the RAS - the RMAPS just propagates it for easy launch.

- only include binaries for ppc/i386 -- no need for 64 bit
- default to not printing load errors so that the XGrid pls
doesn't cause errors when doing 64 bit builds

open MTL MX and BTL MX and initialize them at the same time. The problem is
that both call mx_init and mx_finalize, solution is to add an external entity
that does the init and finalize (based on ref counting).
This commit was SVN r13576.
The C++ bindings were not tracking keyvals properly -- they were
freeing some internal meta data when Free_keyval() was called, not
when the keyval was actually destroyed (keyvals are refcounted in the
C layer, just like all other MPI objects, because they can live for
long after their corresponding Free call is invoked). This commit
fixes this problem and several other things:
* Add infrastructure on the ompi_attribute_keyval_t for an "extra"
destructor pointer that will be invoked during the "real"
constructor (i.e., when OBJ_RELEASE puts the refcount to 0). This
allows calling back into the C++ layer to release meta data
associated with the keyval.
* Adjust all cases where keyvals are created to pass in relevant
destructors (NULL or the C++ destructor).
* Do essentially the same for MPI::Comm, MPI::Win, and MPI:Datatype:
* Move several functions out of the .cc file into the _inln.h file
since they no longer require locks
* Make the 4 Create_keyval() functions call a common back-end
keyval creation function that does the Right Thing depending on
whether C or C++ function pointers were used for the keyval
functions. The back-end function does not call the corresponding
C MPI_*_create_keyval function, but rather does the work itself
so that it can associate a "destructor" callback for the C++
bindings for when the keyval is actually destroyed.
* Change a few type names to be more indicative of what they are
(mostly dealing with keyvals [not "keys"]).
* Add the 3 missing bindings for MPI::Comm::Create_keyval().
* Remove MPI::Comm::comm_map (and associated types) because it's no
longer necessary in the intercepts -- it was a by-product of being
a portable C++ bindings layer. Now we can just query the C layer
directly to figure out what type a communicator is. This solves
some logistics / callback issues, too.
* Rename several types, variables, and fix many comments in the
back-end C attribute implementation to make the names really
reflect what they are (keyvals vs. attributes). The previous names
heavily overloaded the name "key" and were ''extremely''
confusing.

Ticket 817 --> https://svn.open-mpi.org/trac/ompi/ticket/817
investivating #817:
* Remove use of legal_numbits member and always just use the full
size of the array. There was a corner case where legal_numbits was
not an even multiple of the number of bits in the array where bits
would not get freed properly, ususally causing wasted fortran
MPI handles, or, as in the case of #817, wasted attribute keyvals
(i.e., the user freed them, but the bitmap didn't reflect the
free).
* Re-order some error checks to ensure that we don't segv (we don't
currently trigger this problem anywhere; I just noticed it while
doing the other attribute keyval and legal_numbits work).
Since this change affects all Fortran MPI handles, I ran all the intel
and ibm tests and all still pass with this change.

- Set ompi-specific autoconf cache-variables
- Implement one function to check for availability of an
attribute with the possibility for a cross-check.
- Do cross-checks for
__attribute__(format)
__attribute__(nonnull)
__attribute__(sentinel)
__attribute__(warn_unused_result)
- Grep the compilers warnings for keywords regarding ignored
attributes.
- Include also the no_instrument_function

This change utilizes the new num_processors function. I also left the mods made to ompi_mpi_init and the bug fix for the default value of mpi_yield_when_idle. Note that the mods to mpi_init will not really take effect as the mca param will now *always* be set (either by user or odls). We will need those mods later, so no point in removing them now.
This commit was SVN r13519.
Add new function opal_get_num_processors() that will return the number
of processors on the local host. Does the Right thing in POSIX
environments (to include a special case for OS X), and will shortly do
the Right Thing for Windows (this commit includes a change to
configure, so I wanted to get that in before the US workday -- the
Windows code can some shortly because it won't involve configury
changes).

go and have proper casting.
Tested with linux gcc-4, icc-9.0, pathcc-2.2.1 and pgi-6.2.5

same for pathcc and pgi)
