#5663: Rework directory watching in daemon Implement BSD/Darwin (kqueue) and Windows (ReadDirectoryChanges) mechanisms for receiving directory change notifications. Use events instead of polling for changes. Retry file parsing up to 3 times before giving up. Huge thanks to missionsix for preparing first two versions of the patch.

Adjust uncrustify config, reformat all but Mac client There're places where manual intervention is still required as uncrustify is not ideal (unfortunately), but at least one may rely on it to do the right thing most of the time (e.g. when sending in a patch). The style itself is quite different from what we had before but making it uniform across all the codebase is the key. I also hope that it'll make the code more readable (YMMV) and less sensitive to further changes.

Align type qualifiers to the right (code style) This way all the qualifiers (`const`, `volatile`, `mutable`) are grouped together, e.g. `T const* const x` vs. `const T* const x`. Also helps reading types right-to-left, e.g. "constant pointer to constant T" vs. "constant pointer to T which is constant".
