can't apply its normal precedence rules.
So...print a big "deprecated" warning for the old params and error out if a conflict is detected. I know that isn't what people really wanted, but it's the best we
can do. If only the old style param is given, then process it after the warning.
Extend the current map-by param to add support for ppr and cpus-per-proc, adding the latter to the list of allowed modifiers using "pe=n" for processing elements/proc. Thus, you can map-by socket:pe=2,oversubscribe to map by socket, binding 2 processing elements/process, with oversubscription allowed. Or you can map-by ppr:2:socket:pe=4 to map two processes to every socket in the allocation, binding each process to 4 processing elements.
For those wondering, a processing element is defined as a hwthread if --use-hwthreads-as-cpus is given, or else as a core.

During the commits to make the C/R code compile again the
blocking receive calls in snapc_full_app.c were
replaced by non-blocking receive calls.
This commit adds ORTE_WAIT_FOR_COMPLETION()
after each non-blocking receive to wait for the data.
This commit was SVN r30487.
During the commits to make the C/R code compile again the
blocking receive calls were replaced by non-blocking
which broke the code. This patch uses ORTE_WAIT_FOR_COMPLETION()
to wait until the non-blocking calls have finished.

The function
int orte_snapc_base_select(bool seed, bool app);
wants to know if it called by an application or not. Therefore
it expects as second paremeter 'bool app'. It used to be
'!ORTE_PROC_IS_DAEMON' which is not always correct if it is
a tool or a HNP. This patch changes it to ORTE_PROC_IS_APP, which
has the correct information if it is an application.

NOTE: launch performance will be absolutely awful if you do this with BTLs that aren't configured to modex_recv on first message!
Even with "modex on demand", we still have to do a barrier in place of the modex - we simply don't move any data around, which does reduce the time impact. The barrier is required to ensure that the other proc has in fact registered all its BTL info and therefore is prepared to hand over a complete data package. Otherwise, you may not get the info you need. In addition, the shared memory BTL can fail to properly rendezvous as it expects the barrier to be in place.
This behavior will *only* take effect under the following conditions:
1. launched via mpirun
2. #procs is greater than ompi_hostname_cutoff, which defaults to UINT32_MAX
3. mca param rte_orte_direct_modex is set to 1. At the moment, we are having problems getting this param to register properly, so only the first two conditions are in effect. Still, the bottom line is you have to *want* this behavior to get it.
The planned next evolution of this will be to make the direct modex be non-blocking - this will require two fixes:
1. if the remote proc doesn't have the required info, then let it delay its response until it does. This means we need a way for the MPI layer to tell the RTE "I am done entering modex data".
2. adjust the SM rendezvous logic to loop until the required file has been created
Creating a placeholder to bring this over to 1.7.5 when ready.
