Introduce 'pr_usrreqs' structure and move existing user-protocol
handlers into it. We want to split existing (*pr_usrreq)() to multiple
short handlers for each PRU_ request as it was already done for
PRU_ATTACH and PRU_DETACH. This is the preparation step, (*pr_usrreq)()
split will be done with the following diffs.

Based on reverted diff from guenther@.

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

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.
