    [ZOOKEEPER-1416] Persistent Recursive Watch

    Here is a completed implementation for a persistent, recursive watch addition for ZK.
These watches are set via a new method, `addPersistentWatch()` and are removed via the existing
watcher removal methods. Persistent, recursive watches have these characteristics:
    - Once set, they do not auto-remove when triggered
    - They trigger for all event types (child, data, etc.) on the node they are registered
for and any child znode recursively.
    - They are efficiently implemented by using the existing watch internals. A new class
`PathIterator` walks up the path parent-by-parent when checking if a watcher applies. 
    Persistent watcher specific tests are in `PersistentWatcherTest.java`. I'd appreciated
feedback on other additional tests that should be added.
