Teach test.c IN_IGNORED event.
Split conversion functions arguments to is_directory and subwatch
It helps to make inotify2kqueue and vice versa flags conversion more fine grained.
Ignore NOTE_EXTEND as it is a flag not an event and is irrelevant to inotify.
Fix extraneous IN_ATTRIB event on subdirectory creations and deletions

Kqueue set NOTE_LINK flag on every subdirectory creation and deletion.
Dont treat it as attributes change and ignore.
NOTE: creating directory in subwatched directory now produces empty event
      It will be fixed later
Send IN_DELETE_SELF only on real delete (link count = 0)

Kqueue send NOTE_DELETE event on every decrease of links counter while inotify
send IN_DELETE_SELF only when link counter reaches zero. So treats NOTE_DELETE
as file attributes change until link counter reaches 0.
Fix subwatch creation when no IN_(CREATE|DELETE|MOVE) flags specified

Watched directory has to be reread every time it changed for keeping list of
subwatches up to date
