* DeferrableUpdate classes can implement MergeableUpdate.
Duplicate updates will be merged via the merge() method.
* Make SquidUpdate support merge() so that duplicate URL
purges are now caught accross the entire pre-send request
execution.

* PRESEND/POSTSEND constants can now be used in addUpdate()
and addCallableUpdate() to control when the update runs.
This is useful for updates that may report errors the client
should see or to just get a head start on queued or pubsub
based updates like CDN purges. The OutputPage::output() method
can easily take a few 100ms.
* Removed some argument b/c code from doUpdates().
* Also moved DeferrableUpdate to a separate file.

Under some configurations all Echo notifications are inserted
via a DeferredUpdate. When an extension delays its own notification
trigger via DeferredUpdate as well the Echo notification will not
be run.
