* Add ability to completely disable libltdl (the dlopen code to load dynamic shared objects) to configure: --disable-dlopen * Added MCA param (component_disable_dlopen) to disable DSO loading at runtime * Made the event library behave in some not-completely-erroneous way on platforms where it has absolutely no eventops support (ie, no select, poll, or epoll) * Disabled orte_wait, opal_few, and opal_daemon_init code on platforms without fork, waitpid support. All non-init functions will return OPMI_ERR_NOT_SUPPORTED * Disable orteprobe tool when fork or pipe aren't supported This commit was SVN r6490.
