all processes call MPI_Gatherv(MPI_IN_PLACE...) because IN_PLACE is
only allowed to be used at the root. Non-root processes must use
their receive buf as the send buf.

the way we use weak symbols (you have to use the actual symbol in the
.o file or the weak symbol isn't generated). It worked for our test
case, but not for libmpi. Make our test case look more like what we
do in libmpi by generating a .o file with a weak symbol and attempting
to use it from another object file.

caller to specify a subset of the state variables that it can can subscribe to.
This is specified with one of three special flags defined in rmgr/rmgr_types.h
This is useful when we only care about a subset of the state changes, such as
in orted which only needs to know when a job has terminated or aborted.

- added relevant logic for everything except
mca_coll_basic_reduce_log_intra() -- need some help from George /
Edgar on this one...
- replaced ompi_ddt_sndrcv() with ompi_ddt_copy_content_same_ddt()
where relevant
- removed some "if (size > 1)" conditionals, because the self coll
module will always be chosen for collectives where size==1
Waiting for BA's tests to check the validity of this IN_PLACE stuff.
We'll see how it goes!

- fix the first test
- make the #define's always have a value (0 or 1)
- prefix them with OMPI
- remove the extra "__"'s in the names, since they're now
OMPI-specific #define names
This commit was SVN r7339.
-added some alltoall calls (pairwise checked ok, bruck testing)
-changes in use of data hung of communicator
-making sendrecv call a true inline function
-more use ompi_ddt routines

waiting instead for the SOH to indicate that the jobid has terminated.
In a scheduled environment, if your program has a section of MPI code
followed by a section of computation that some processes execute while
other proceses terminate normally. This patch keeps the scheduler from
terminating all of the processes and the allocation if all of the processes
on an allocated node exit well before other processes on other nodes.

They can be used to give additional knowledge to the compiler about the behaviour of a
function so it can optimize further. In the begining we just need it for the alias weak
a better way to create function aliases.
The problem was that the intel compiler version 8 to 9 support pragma weak but do not include
the function in the .o file if it's not used at least once in the same .c file. With the
alias weak this problem is solved as even intel support it correctly.
