the client watch impl

The client subscribes to store update notifications via a go
channel. The go channel is only used to send a bit 'there is
a watch log update'. Whenever a client sees the notification,
it scans through the watch log for new updates (like the sync
watcher does), filters out unnecessary or inaccessible log
records and sends the result to the client.
