core/path: install inotify watches top-down instead of bottom-up
When watches are installed from the bottom, it is always possible to race, and miss a file creation event. The race can be avoided if a watch is first established for a parent directory, and then for the file in the directory. If the file is created in the time between, the watch on the parent directory will fire. Some messages (mostly at debug level) are added to help diagnose pidfile issues. Should fix https://bugzilla.redhat.com/show_bug.cgi?id=917075.
