Set up a dns check for both changes

This way I can get email no matter what fails
Save original dns in a well-known location

This lets us recover from errors more easily
Add some overrides for important hosts to named
More logging in passthrough filter

Also, add the rest of the stone ridge hosts for completeness' sake
Use stone ridge logging configuration in named

Instead of whatever crap google is doing in their configure_logging
statement.
More logging fixups in named
Make srnamed use stone ridge daemonization

This lets the logging work properly (because daemonize is crap). I will
also be able to remove daemonize as a dependency, as this was the last
thing that used it.
Remove daemonize as a requirement

It's no longer needed, as of the previous commit.
Make exception hosts REALLY fully qualified

We get the value with the root '.' at the end, so we need to check
against that.
