Mark Salyzyn 2ad0bd0a9b logd: Allow (some) headers to be individually importable
LogReader.h needs to be individually importable.

Fix a few others, drop includes of local includes, let them be
included in source instead and allow headers to be included
alphabetically. Was not a complete audit since goal was to
separate LogReader.h out from the pack.
