So the compiler can start warning about namespaces typed as "Object", fixup the ones in closure.

Change ToolbarSeparatorRenderer to include the control's extra CSS classes.

It's a minor change, but this makes ToolbarSeparator be more in line with expected goog.ui.Control rendering behavior.

Fix several lint errors in Closure.

These changes mostly affect goog.requires and goog.provides - we're moving closer to a world in which Closure only requires and provides what it actually needs, but there are still several existing circular dependencies in the codebase.

I ran fixjsstyle --strict --limited_doc_files=_test.js
--closurized_namespaces=goog and then reverted silly changes it made.

Updates the externs for window.setTimeout() and window.setInterval() in accordance with the HTML5 spec's modification to the spec which sets an explicit default value for the delay parameter (0), thus making them optional. See https://html.spec.whatwg.org/multipage/webappapis.html#timers for more information.

This CL was requested in response to updating the MockClock Closure library in cl/78778434.

Remove conformance whitelist of innerHTML for divconsole.js and instead use goog.dom.safe.setInnerHtml().

To do this:
- HtmlFormatter now has a formatRecordAsHtml() which returns SafeHtml.
- DivFormatter.setFormatter() only accepts an HtmlFormatter. This should've been the case before, since it uses innerHTML; a TextFormatter would've been unsafe.
- SafeHtml.htmlEscapePreservingNewlinesAndWhitespace() is introduced for HtmlFormatter.formatRecordAsHtml().

Deprecate the (new) goog.string.isEmptyOrWhitespaceSafe function.

The function was added as part of the preamble to the work described in go/lsc-goog-string-isempty, but in the end it was decided not to migrate to this function.  Deprecate it so that it doesn't get adopted too widely for now.  Once the linked LSC is done, a followup CL will be created to fix remaining clients, and to remove this function.

Add support for responseType in goog.labs.net.Xhr,
and the convenience function getBytes() for fetching
binary files as an array of bytes.

Disabled for IE8 and earlier, which does not support
reading the bytes of a response without a disturbing
amount of VBScript.
