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}}}
