1. implement and enable the non-described buffer operations. I will send out a more detailed explanation separately. However, this mode of operation (which is now the default) significantly reduces message size during startup. If you want the described buffers, set the mca param "-mca dss_describe_buffer 1".
2. revise the xcast system to support both linear and binomial tree broadcast methods. Since we are seeing scenarios where the binomiall tree can cause problems, I have made the linear method the default. To run with the binomial tree, set the mca param "-mca oob_xcast_mode binomial".
3. add some detailed timing reports to the xcast operation. These are enabled via "-mca oob_xcast_timing 1".
4. add some more unit tests for the dss and gpr (focused on support for the non-described buffer)

Accordingly, there are new APIs to the name service to support the ability to get a job's parent, root, immediate children, and all its descendants. In addition, the terminate_job, terminate_orted, and signal_job APIs for the PLS have been modified to accept attributes that define the extent of their actions. For example, doing a "terminate_job" with an attribute of ORTE_NS_INCLUDE_DESCENDANTS will terminate the given jobid AND all jobs that descended from it.
I have tested this capability on a MacBook under rsh, Odin under SLURM, and LANL's Flash (bproc). It worked successfully on non-MPI jobs (both simple and including a spawn), and MPI jobs (again, both simple and with a spawn).

- use the OPAL functions for PATH and environment variables
- make all headers C++ friendly
- no unamed structures
- no implicit cast.
Plus a full implementation for the orte_wait functions.

ORTE_DECLSPEC and OMPI_DECLSPEC. Please use them based on the sub-project.

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. Introduces a flag for the type of buffer that now allows a user to either have a fully described or a completely non-described buffer. In the latter case, no data type descriptions are included in the buffer. This obviously limits what we can do for debugging purposes, but the intent here was to provide an optimized communications capability for those wanting it.
Note that individual buffers can be designated for either type using the orte_dss.set_buffer_type command. In other words, the buffer type can be set dynamically - it isn't a configuration setting at all. The type will default to fully described. A buffer MUST be empty to set its type - this is checked by the set_buffer_type command, and you will receive an error if you violate that rule.
IMPORTANT NOTE: ORTE 1.x actually will NOT work with non-described buffers. This capability should therefore NOT be used until we tell you it is okay. For now, it is here simply so we can begin bringing over parts of ORTE 2.0. The problem is that ORTE 1.x depends upon the transmission of non-hard-cast data types such as size_t. These "soft" types currently utilize a "peek" function to see their actual type in the buffer - obviously, without description, the system has no idea how to unpack these "soft" types. We will deal with this later - for now, please don't use the non-described buffer option.
2. Introduces the orte_std_cntr_t type. This will become the replacement for the size_t's used throughout ORTE 1.x. At the moment, it is actually typedef'd to size_t for backward compatibility.
3. Introduces the orte_dss.arith API that supports arbitrary arithmetic functions on numeric data types. Calling the function with any other data type will generate an error.

- The constant 1 is a signed int by default. Explicitly say that
it is an unsigned value so we can't overflow
- Fix unreachable statement warnings in dss_arith by breaking out
of switch statements instead of returning - this should have
no impact on performance, since it's a non-conditional jump
- A couple of the GPR files had carriage returns and were in
DOS mode - put them in unix mode...
These should all probably go to the v1.1 branch...

- move files out of toplevel include/ and etc/, moving it into the
sub-projects
- rather than including config headers with <project>/include,
have them as <project>
- require all headers to be included with a project prefix, with
the exception of the config headers ({opal,orte,ompi}_config.h
mpi.h, and mpif.h)
