* Variable names to conform to naming convention.

* Use static constants where it makes sense

This changes SharedState.registeredEventListeners to be a Map that keeps track of how many listeners of each type have been added, and handles unregistering of such listeners correctly.

And remove unused imports.

And change private member to List instead of ArrayList

Fixes #9883

Fix since tags for the server and shared modules and new types in client.

Fixes vaadin/framework8-issues#399
RemoveListenersDeprecatedTest test is fixed.
Corrections are made to make the test above passes.

This patch updates server side add*Listener methods to return
a registration object and deprecates their corresponding
remove*Listener methods.

Additionally this patch removes add/removeListener methods which were
deprecated in 7.0.

Reduces time spent in findStateType() for the "40 layouts" action in
BasicPerformanceTest from around 2 ms to around 0.2 ms. This improves
the total performance of the action by about 5%.

Comparisons with the ==-operator between a proxy and it's underlying
instance fail, so we should use a custom equals method instead.

API change from:
    public static Iterable<ClientConnector> getAllChildrenIterable(final ClientConnector connector)
to
    public static Iterable<? extends ClientConnector> getAllChildrenIterable(final ClientConnector connector)

avoids creating wrappers in case the component has either no subcomponents
or no extensions. This covers the vast majority of components.

Many core vaadin components did incorrectly mark the state as dirty when
reading from them. This patch fixes the problem, which should reduce the
amount of server->client state updates significantly.

getAllChildrenIterable() is invoked frequently, its used by
attach/detach and markAsDirty.
Because of the implementation detail in CombinedIterator, on every call
all iterators are checked. This means that on every component which has
multiple childs, each next() call will first check the extension
iterator, before advancing in the child iterator.
By having the childs first, this overhead is reduced. If no extensions
are existing (which is quite common) the iterator is not added at all.
(creating an iterator on an empty UnmodifiableCollection is waste of
time and memory)
