Change conversion routines to use kqueue watch flags as argument
Move inotify to kqueue flag conversion code to watch.c from separate file
It becomes too highly integrated with watch internals.
Inherit watch flags from struct mode_t type
It`s possible to use stat(2) S_* macroses on watch flags now.
Implement IN_OPEN, IN_CLOSE and IN_ACCESS inotify events
It is done via adding new kqueue events: NOTE_OPEN, NOTE_CLOSE and NOTE_READ
