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.
