Fix macro spelling.

split PRU_CONNECT, PRU_RCVOOB and PRU_SENDOOB into separate functions
(all implemented as EOPNOTSUPP).
Note import of dhcpcd-6.4.3
* remove declarations of unp_bind, unp_discard, unp_disconnect1, unp_drop,
  unp_shutdown1, unp_internalize and unp_output functions from sys/un.h
  and  instead declare them as static in uipc_usrreq.c with prototype
  declarations as necessary.

* remove struct lwp * parameter from unp_output() while here and just
  use curlwp instead.

as discussed with rmind
Remove the variable not used anymore.
sync with x68k/pmap_bootstrap.c,v 1.21 (in 2001).
release mbuf on failure of PRU_SEND
add missing \n

from Robert Millan <rmh@freebsd.org> via rumpkernel-users
call ->pr_abort(so) now instead of generic PRU_ABORT.
fixes kern/49056, and appears to remove the only missed PRU_ABORT call.
powerpc*-netbsd*: include netbsd-elf.h after sysv4.h
