FS-6506 --resolve Technically when you are not using groups you do not add a <users> tag inside <domain> you just put several <user> tags in <domain> This patch will consume an extraneous <users> tag and move on making it work either way.

FS-353: look for ldns pkg-config for homebrew, you will need to update your homebrew ldns package if you installed it prior to this commit, they just fixed the pkg-config file being installed

POSIX says poll.h and signal.h should not be prefixed with sys/ (ie
