This change does a couple of things:
1. Since the USE_PARENT_ALLOC attribute is a directive about regarding allocation of resources to a job, it more properly should be an attribute of the RAS. Change the name to reflect that and move the attribute define to the ras_types.h file.
2. Add the attributes list to the RMAPS map_job interface. This provides us with the desired flexibility to dynamically specify directives for mapping. The system will - in the absence of any attribute-based directive - default to the values provided in the MCA parameters (either from environment or command-line interface).

Fix the problem observed by multiple people that comm_spawned children were (once again) being mapped onto the same nodes as their parents. This was caused by going through the RAS a second time, thus overwriting the mapper's bookkeeping that told RMAPS where it had left off.
To solve this - and to continue moving forward on the ORTE development - we introduce the concept of attributes to control the behavior of the RM frameworks. I defined the attributes and a list of attributes as new ORTE data types to make it easier for people to pass them around (since they are now fundamental to the system, and therefore we will be packing and unpacking them frequently). Thus, all the functions to manipulate attributes can be implemented and debugged in one place.
I used those capabilities in two places:
1. Added an attribute list to the rmgr.spawn interface.
2. Added an attribute list to the ras.allocate interface. At the moment, the only attribute I modified the various RAS components to recognize is the USE_PARENT_ALLOCATION one (as defined in rmgr_types.h).
So the RAS components now know how to reuse an allocation. I have debugged this under rsh, but it now needs to be tested on a wider set of platforms.

something went wrong. A positiv number > 0 is however a correct value (in
contrary to orte_rml.recv_buffer, which really returns ORTE_SUCCESS or an

long ago) supposed to be used as a cache for accessing the PML procs. But in
all of the PMLs the PML proc contain only one field i.e. a pointer to the ompi_proc.
This pointer can be accessed using the c_remote_group easily. Therefore, there is no
meaning of keeping the PML procs around. Slim fast commit ...

Other changes:
1. Remove the old xcpu components as they are not functional.
2. Fix a "bug" in orterun whereby we called dump_aborted_procs even when we normally terminated. There is still some kind of bug in this procedure, however, as we appear to be calling the orterun job_state_callback function every time a process terminates (instead of only once when they have all terminated). I'll continue digging into that one.
This will require an autogen/configure, I'm afraid.
This commit was SVN r11228.
Clean up the remainder of the size_t references in the runtime itself. Convert to orte_std_cntr_t wherever it makes sense (only avoid those places where the actual memory size is referenced).
Remove the obsolete oob barrier function (we actually obsoleted it a long time ago - just never bothered to clean it up).
I have done my best to go through all the components and catch everything, even if I couldn't test compile them since I wasn't on that type of system. Still, I cannot guarantee that problems won't show up when you test this on specific systems. Usually, these will just show as "warning: comparison between signed and unsigned" notes which are easily fixed (just change a size_t to orte_std_cntr_t).
In some places, people didn't use size_t, but instead used some other variant (e.g., I found several places with uint32_t). I tried to catch all of them, but...
Once we get all the instances caught and fixed, this should once and for all resolve many of the heterogeneity problems.

1. comm_spawn processes by default will inherit the "--prefix" from their parent job. Thus, the "--prefix" provided on the command line will be propagated automatically to any children.
2. application programs can override the default by providing their own "ompi_prefix" in the MPI_Info parameter passed to comm_spawn

comment in ompi_comm_invalid() in
source:/trunk/ompi/communicator/communicator.h.
Short version:
- ompi_comm_invalid() returns TRUE for MPI_COMM_NULL
- therefore MPI_COMM_C2F needs to explicitly check for MPI_COMM_NULL
(because it uses ompi_comm_invalid())
- make ~20 MPI functions only call ompi_comm_invalid() instead of
calling ompi_comm_invalid() *and* checking for MPI_COMM_NULL (~40 MPI
functions already only called ompi_comm_invalid() -- we should be
consistent)
- similar issue for ompi_win_invalid(), so I added a cross-referencing
comment in win.h and fixed MPI_WIN_SET_NAME to only call
ompi_win_invalid() (and not check for MPI_WIN_NULL)

- My original patch stands: MPI_FINALIZE directly invokes the
attribute callbacks on MPI_COMM_SELF
- We added some user-level checks to ensure that they don't call
MPI_FINALIZE twice (this isn't really required, but it will prevent
whacky segv's -- they'll at least get a nice error message)
- Removed the attribute callbacks on MPI_COMM_SELF from
ompi_mpi_comm_finalize (i.e., we just moved them from
ompi_mpi_comm_finalize to ompi_mpi_finalize -- we just moved this
process up earlier in the MPI_FINALIZE sequence of events)
- Because there were so many conversations about this, here's the
rationale:
- MPI-2:4.8 says that we have to MPI_COMM_FREE MPI_COMM_SELF so that
the attribute callbacks are invoked.
- After considerable discussion, we came to the conclusion that
FREE'ing COMM_SELF is not the issue -- calling the callbacks is
the issue.
- So it is sufficent for MPI_FINALIZE to directly invoke these
attribute callbacks
- The attribute callbacks are *not* invoked on other communicators
because said communicators are not MPI_COMM_FREE'ed

originally suggested by Ralf Wildenhues, to try to speed autogen, configure,
and make (and possibly even make install). Use automake's include directive
to drastically reduce the number of Makefile files (although the number of
Makefile.am files is the same - most are just included in a top-level
Makefile.am). Also use an Automake SUBDIRs feature to eliminate the
dynamic-mca tree, which was no longer really needed. This makes adding
a framework easier (since you don't have to remember the dynamic-mca
tree) and makes building faster (as make doesn't have to recurse through
the dynamic-mca tree)

AM_INIT_AUTOMAKE, instead of the deprecated version.
* Work around dumbness in modern AC_INIT that requires the version
number to be set at autoconf time (instead of at configure time, as
it was before). Set the version number, minus the subversion r number,
at autoconf time. Override the internal variables to include the r
number (if needed) at configure time. Basically, the right thing
should always happen. The only place it might not is the version
reported as part of configure --help will not have an r number.
* Since AM_INIT_AUTOMAKE taks a list of options, no need to specify
them in all the Makefile.am files.
* Addes support for subdir-objects, meaning that object files are put
in the directory containing source files, even if the Makefile.am is
in another directory. This should start making it feasible to
reduce the number of Makefile.am files we have in the tree, which
will greatly reduce the time to run autogen and configure.
