In order to have an effect, ibv_fork_init should be called in the beginning of the verbs initialization flow - before the calls to the ibv_create_qp and ibv_create_cq verbs. These functions are called from the oob/ud code and by the time the other verbs components (btl openib, pml yalla, ...) call ibv_fork_init, it's too late. This commit forces the call to ibv_fork_init (if it's requested) right at the beginning of all the components that are using verbs. (ibv_fork_init() can be safely called multiple times) This commit also removes the btl_openib_want_fork_support mca parameter and adds a new mca parameter instead - opal_verbs_want_fork_support. Through this new parameter, fork support may be requested for ALL components. The default value for this parameter is set to 1. Before this commit the btl_openib_want_fork_support parameter didn't provide fork support for the openib btl if its value was set to 1. (because when openib called ibv_fork_init, it was already after the calls to ibv_create_* in oob/ud and thereofre it failed).
