This *should* fix following situation:
1 mxm.rpm puts /etc/ld.so.conf.d/mxm.conf file during rpm install with libpath to /opt/mellanox/mxm/lib
2 some1 can extract mxm.rpm into $HOME/mxm and compile OMPI with new mxm location
3 during runtime, OMPI from prev step will pick MXM from step (1) instead of from step (2)

- Use ->boolval for booleans when creating a string.
- Solaris has some issue with the ?: used in one of find functions. Use an if instead.
- Change all instances of index -> vari to avoid issues with redefining index.

* Puts the DO_DEBUG macros back in the .c files, because they are

Solaris/SPARC.
This commit properly moves the extern to a .h file so that it's the
same in all files. It also moves the DO_DEBUG to the header file,
because it was defined to the same thing in multiple .c files.

Reset topology usage for each node as we bind as multiple nodes may be linked to the same topology object. This will need to be revisited for scale as it does take some non-zero time to reset the usage each iteration. However, storing individual topology objects for every node consumes memory, so it's a tradeoff.

to be consistent this way...

* automatically retrieve the hostname (and all RTE info) for all procs during MPI_Init if nprocs < cutoff
* if nprocs > cutoff, retrieve the hostname (and all RTE info) for a proc upon the first call to modex_recv for that proc. This would provide the hostname for debugging purposes as we only report errors on messages, and so we must have called modex_recv to get the endpoint info
* BTLs are not to call modex_recv until they need the endpoint info for first message - i.e., not during add_procs so we don't call it for every process in the job, but only those with whom we communicate
My understanding is that only some BTLs have been modified to meet that third requirement, but those include the Cray ones where jobs are big enough that launch times were becoming an issue. Other BTLs would hopefully be modified as time went on and interest in using them at scale arose. Meantime, those BTLs would call modex_recv on every proc, and we would therefore be no worse than the prior behavior.
This commit revises the MPI-RTE interface to pass the ompi_proc_t instead of the ompi_process_name_t for the proc so that the hostname can be easily inserted. I have advised the ORNL folks of the change.
