 * Control sockets are not opened in test mode
 * privsep: no longer aborts if protocol not available
 * inet6: Don't regen temporary addresses without a state
 * inet6: Reduce RA log spam
 * dhcp6: Don't log when things consitently fail
 * inet6: Add temporary directive to slaac option [1]
 * Ensure current interface flags persist when setting a flag
 * DHCP via BPF is now aligned correctly
 * CMSG buffers are now aligned correctly
 * hostnames are no longer clobbered when being forced and a RA is recieved

[1] dhcpcd no longer looks at any possible kernel settings when deciding to
manage IPv6 temporary addresses or not. You now instruct dhcpcd to do this
in dhcpcd.conf. Playing whack-a-mole with various kernel knobs wasn't fun
and some OS's have or are removing RA and thus temporary address managemnt
from the kernel so said knobs are no longer there.
