Because all the necessary refactors to the logging code have been merged for some time already, now it's time to finally enable the logging APIs. Since there's been an effort to deprecate the concept of the log_level setting in the config (as per discussion [1]), I dropped patches introducing APIs handling the logging level, even though I still think that for an average user it's easier to just turn on debug logs by setting log_level to 1 compared to the alternative way using filters only - kind of like this: "1:conf 1:cpu 1:network 1:secret 1:security 1:storage 1:qemu 1:util" etc. to override the default global logging level 3. Since we treat an unset log_output variable the same way as an explicit empty string in the config - we use a default logging output - it is necessary to store the default logging output we can fallback to later once a user tries to set the logging outputs to an empty string, assuming that it would turn the logging off (which kind of would be the intuitive approach) which it can't, since the only way to do it is to use X:file:/dev/null. The decision for the default logging output is supposed to be made at the daemon's start only and we should really only use getters throughout our code to retrieve the default output, not try to set it (because the variable is not protected by a mutex by design for the reason above).
