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.

allocation. This is necessary to detect if the user requests a specific
mpool for the allocationi. Searching the key values for a specific mpool
name does not work for the case that the user provides an info object
without mpool specific information (see Ticket #254).
- In the case that the user provides a info object without requesting a
specific mpool we use malloc to allocate buffer instead of returning
NULL (fix for Ticket #254 )

addition to my design and testing, it was conceptually approved by
Gil, Gleb, Pasha, Brad, and Galen. Functionally [probably somewhat
lightly] tested by Galen. We may still have to shake out some bugs
during the next few months, but it seems to be working for all the
cases that I can throw at it.
Here's a summary of the changes from that branch:
* Move MCA parameter registration to a new file (btl_openib_mca.c):
* Properly check the retun status of registering MCA params
* Check for valid values of MCA parameters
* Make help strings better
* Otherwise, the only default value of an MCA param that was
changed was max_btls; it went from 4 to -1 (meaning: use all
available)
* Properly prototyped internal functions in _component.c
* Made a bunch of functions static that didn't need to be public
* Renamed to remove "mca_" prefix from static functions
* Call new MCA param registration function
* Call new INI file read/lookup/finalize functions
* Updated a bunch of macros to be "BTL_" instead of "ORTE_"
* Be a little more consistent with return values
* Handle -1 for the max_btls MCA param
* Fixed a free() that should have been an OBJ_RELEASE()
* Some re-indenting
* Added INI-file parsing
* New flex file: btl_openib_ini.l
* New default HCA params .ini file (probably to be expanded over
time by other HCA vendors)
* Added more show_help messages for parsing problems
* Read in INI files and cache the values for later lookup
* When component opens an HCA, lookup to see if any corresponding
values were found in the INI files (ID'ed by the HCA vendor_id
and vendor_part_id)
* Added btl_openib_verbose MCA param that shows what the INI-file
stuff does (e.g., shows which MTU your HCA ends up using)
* Added btl_openib_hca_param_files as a colon-delimited list of INI
files to check for values during startup (in order,
left-to-right, just like the MCA base directory param).
* MTU is currently the only value supported in this framework.
* It is not a fatal error if we don't find params for the HCA in
the INI file(s). Instead, just print a warning. New MCA param
btl_openib_warn_no_hca_params_found can be used to disable
printing the warning.
* Add MTU to peer negotiation when making a connection
* Exchange maximum MTU; select the lesser of the two

implemented entirely on top of the PML. This allows us to have a
one-sided interface even when we are using the CM PML and MTLs for
point-to-point transport (and therefore not using the BML/BTLs)
* Old pt2pt component was renamed "rdma", as it will soon be having
real RDMA support added to it.
