This allows replacing the mem name with mr for MRs which is more consistent with the style for the other objects and less likely to be confusing. This is a long patch that just changes mem to mr where it makes sense.

Added a random key generator for each type. Added responses for ibv_reg_mr and ibv_alloc_mw with the assigned indices so other verbs can refer to them by index. Changed key lookups to rxe_pool_get_key instead of rxe_pool_get_index.

Added an extra flags field in the rxe WQE to indicate whether the bind operation came from the ibv_bind_verbs API or the ibv_post_send API to enforce the rules on type 1 and 2 MWs.
