The new locateUsersWatchingTitle implementation could end up returning
thousands of users, currently on enwiki there are 25 titles with more
than 10k subscribed users and aprox 550 titles with more than 1k subscribed
users.
This switches the user collection to an iterator based implementation so that
we no longer need to have the entire users list at any one time.

Replace implementation specific code with generalized user-locator
implementations that can be re-used by more notifications in other
extensions.
This patch adjusts the `user-locators` notification parameter to allow
arrays which facilitate passing options to the locator.
Previously(still works):
'user-locators' => array( 'foo', 'bar' ),
New functionality:
'user-locators' => array(
'foo',
array( 'bar', 42 )
)
In the second example the callback specified by `bar` will receive
an EchoEvent as the first argument and array( 42 ) as its second
argument.

There are a variety of generic strategies you could define to choose
which users should be notified about an event, such as 'users watching
the title' or 'talk page owner' (User_talk only).
This adds a new way to generically implement these in Echo and expose them
to other extensions rather than having each extension implement these
generic strategies themselves.
This patch only converts one notification, edit-user-talk. The remaining
notifications will be converted in future patches. The first user of this
will be Flow for notifying all users watching a particular talk page in

The users watching title implementation provided here is minimalist, a larger
refactor to accomidate pages with thousands of watchers is being handled
in I3d3fa9328f348bb48682d3658622952ce82d3925
