Add monitoring support via kqueue(2). Based on patch from FreeBSD ports, authored by wg@FreeBSD.org and se@FreeBSD.org. However, this version doesn't create any thread, it uses main event dispatcher.

Browse Source 
Some effort was made to unify monitoring via kqueue and via inotify
APIs. Now both provide their implementation of add_watch() function.

I guess there are some logical bugs in vnode_process(). With this commit
it would be better provide code as is, and resolve bugs separately.
