Log message:
	Make the Windows native event dispatch code more stable,
	by introducing two methods:
	 WinDispatcher::callback_bad_handle()
	 WinDispatcher::callback_bad_socket(XorpFd& fd)
	
	Previously if we encountered a bad handle in
	WinDispatcher::wait_and_dispatch(), we would blow
	up with XLOG_FATAL(). Now we proactively dispatch
	all callbacks registered on any bad handles in
	the array, just like SelectorList does.
	
	Sockets, however, are a special case. We rely on
	WSAEnumNetworkEvents() to detect bad sockets, because
	the handles registered and thus visible to
	callback_bad_handle() are actually Event handles
	used to dispatch events on each socket and not the
	sockets themselves with which there is a 1:1
	correspondence.
	
	If we detect a bad socket, we do the same as for
	a bad handle.
	
	While we are here fix some nits in error messages
	in the asserts for fatal edge cases around WFMO.
