This patch contains the following items:
* Fix the flag passed to open() for the read side of the named pipe between the local and app coordinator. There is a race condition when using O_RDWR on a named pipe (not sure how that bug got in there in the first place).
* Adjust control in the C/R thread timing
* Clarify return code in BLCR component
* Allow the user to adjust the max wait time for the named pipes in the FileM local coordinator by using the MCA parameter "snapc_full_max_wait_time" (Default: 20 seconds)
* If the application terminates while there are active FileM operations, force mpirun to wait on these operations to complete.
* Allow the user to set the local copy command (Default: cp) via MCA parameter "filem_rsh_cp"
* Implement the ability to throttle the number of outgoing connections in FileM. At larger scales this type of explicit throttling helps prevent overwhelming the HNP machine. Default: 10, set via MCA parameter: {{{filem_rsh_max_outgoing}}}

* Improved timing in SnapC Full Global Coordinator
* Improved scalability of the SnapC Full protocol
* Minor improvements to the error reporting mechanisms in SnapC and FileM
* Improved the memory usage of the metadata routines - now the owner of the data is more explicit.
* Added a FileM hint to indicate when files stored locally can be moved to/from a globally mounted file system using just the 'cp' command instead of the 'rcp/scp' command. Slightly improves performance, but not too drastically. Can be set using the following SnapC MCA parameter: {{{snapc_base_global_shared=1}}}
* Implement the ability to throttle the number of outgoing connections in FileM. At larger scales this type of explicit throttling helps prevent overwhelming the HNP machine. Default: 10, set via MCA parameter: {{{filem_rsh_max_outgoing}}}
* Add a few diagnostic/debugging features to SnapC and FileM.

Cleanup the termination in orterun when abnormally commanded via ctrl-c. We can just directly terminate_orteds as the orteds always kill any lingering local procs before exiting - no need to do the two-step cha-cha.

Since I already had some changes in there, add in the rmaps rank_file changes - should work okay, but not fully tested.

- Delete unnecessary header files using
contrib/check_unnecessary_headers.sh after applying
patches, that include headers, being "lost" due to
inclusion in one of the now deleted headers...
In total 817 files are touched.
In ompi/mpi/c/ header files are moved up into the actual c-file,
where necessary (these are the only additional #include),
otherwise it is only deletions of #include (apart from the above
additions required due to notifier...)
- To get different MCAs (OpenIB, TM, ALPS), an earlier version was
successfully compiled (yesterday) on:
Linux locally using intel-11, gcc-4.3.2 and gcc-SVN + warnings enabled
Smoky cluster (x86-64 running Linux) using PGI-8.0.2 + warnings enabled
Lens cluster (x86-64 running Linux) using Pathscale-3.2 + warnings enabled

several header files (previously included by header-files)
now have to be moved "upward".
This is mainly system headers such as string.h, stdio.h and for
networking, but also some orte headers.

any arbitrary command as a notifier, potentially allowing just about
anything to be a notifier. This component forks a child during
orte_init() to avoid forking problems with some OS-bypass networks.
The following MCA parameters are available:
notifier_command_cmd:
Default: /sbin/initlog -f $s -n "Open MPI" -s "$S: $m (errorcode: $e)"
Command to execute, with substitution. $s = integer severity; $S =
string severity; $e = integer error code; $m = string message
notifier_command_timeout:
Default: 30
Timeout (in seconds) of the command

We currently apply all of the MCA params in the parent job to the child. This commit allows a user to specify additional params for the child job, and to override any pre-existing params with the new value so they can better control behavior of the child job.
