This commit allows to control output during abnormal oshmem/ompi application termination. Fixed issue in backtrace output. HAVE_BACKTRACE was never set so user was limited in control of this variable. Two related mca variables are moved to opal layer. Corresponding aliases are added for ompi and oshmem.
