Move pr_attach and pr_detach to a new structure pr_usrreqs that can

then be shared among protosw structures, following the same basic
direction as NetBSD and FreeBSD for this.

Split PRU_CONTROL out of pr_usrreq into pru_control, giving it the
proper prototype to eliminate the previously necessary casts.
