Remove the invisible body in support; Add temporary tests to verify correct support completions for upcoming support changes.

Since .trigger() already bubbles the event, we don't have to work around the non-bubbling IE events for that case.

This also provides a resolution for #10699.

At this point the unit test is only testing our ability to fake-fire focusin the right way. These machinations are related to the problem in #6705.

We can't take the blow-it-all-away shortcut because something in the middle of the list may be a mapped special event. On the bright side, -22!

Move clearing the support vars to before the offset doc ready call in case the offset tests are run synchronously. Fixes #10737.

- Adding a test for this would probably slow the manipulation tests significantly, but it's simple enough.

This means no manually triggered event named "load" can bubble, so avoid that name for delegated custom events.

Have Deferred.always return the object onto which it is currently attached to enable true chainability. Fixes #10723. Unit tests added.

We can't use jQuery.error to rethrow anymore since it constructs a new Error from its supposedly-string arg. Also, older IE stringifies Error objects into "[object Error]" so I've loosened the unit test criteria.

This reverts commit 586fb059.

This reverts commit cc4a9996.

Remove test of the invalid object for IE9's sake; Rewrite the appropriate support test for html5 clone caching. Fixes #10682
