branches: 1.1.1.4.6;
Import openresolv-3.4.5 with the following changes since the last version:
* More printf portabitiy fixes.
* Use read -r to avoid backslash problems.
* If we have a valid domain, put that in resolv.conf as well as search.
This does not fix a technical problem, just stops me getting bug reports.
* Update metric and privacy even if resolv.conf didn't change.
* sortlist is now supported.
* Ensure subscriber config directories exist before writing the configs
* Don't create pdnsd.conf if it doesn't exist or is not writeable.
