- Split out kern_accept(), kern_getpeername(), and kern_getsockname() for

  use by ABI emulators.
- Alter the interface of kern_recvit() somewhat.  Specifically, go ahead
  and hard code UIO_USERSPACE in the uio as that's what all the callers
  specify.  In place, add a new uioseg to indicate what type of pointer
  is in mp->msg_name.  Previously it was always a userland address, but
  ABI emulators may pass in kernel-side sockaddrs.  Also, remove the
  namelenp field and instead require the two places that used it to
  explicitly copy mp->msg_namelen out to userland.
- Use the patched kern_recvit() to replace svr4_recvit() and the stock
  kern_sendit() to replace svr4_sendit().
- Use kern_bind() instead of stackgap use in ti_bind().
- Use kern_getpeername() and kern_getsockname() instead of stackgap in
  svr4_stream_ti_ioctl().
- Use kern_connect() instead of stackgap in svr4_do_putmsg().
- Use kern_getpeername() and kern_accept() instead of stackgap in
  svr4_do_getmsg().
- Retire the stackgap from SVR4 compat as it is no longer used.
