* Revert "Add RequireFeaturesAsync() that works regardless order of app init"
* Add mutex to injection resolution
- Turns out we already support async DI resolution regardless of feature ordering
Previous code contain a race condition causing some resolution is lost
- Note that the new mutex cover s.pendingResolutions and s.features
but must not cover callbackResolution() due to deadlock
- Refactor some method names and simplify code
* Add OptionalFeatures injection
For example OptionalFeatures() is useful for fakedns module
* Refactor log
* Add new log methods
* Fix logger test
* Change all logging code
* Clean up pathObj
* Rebase to latest main
* Remove invoking method name after the dot
