memory hooks (munmap) and initialize the mallopt component, and nothing else. Use this mpool in the MX common initialization, supporting both BTL and MTL. Automatically set the MX_RCACHE environment variable to enable registration cache in MX. Tested with success for munmap() and large free(). This commit was SVN r20003.
