By doing the following:
1) Avoid deferring commits until draw if not drawing soon.
2) Don't send BeginMainFrame if swap throttling will block commit.

As a side-effect, some of the changes will also help release
the main thread sooner in some cases where we were holding on to
it for too long.

Additional scheduler deadlock tests added to verify existing
and future operation.

This should also enable us to more easily avoid unconditionally
setting active_tree_needs_first_draw_ to false in
SchedulerStateMachine::UpdateStateOnInvalidateOutputSurface
in followup patches if we want to.

This CL prevents sync from updating the "last updated time" for bookmark
favicons each time that Chrome is started. The "last updated time" determines
when the favicon is redownloaded from the web (in case it has been updated).

Sync calls HistoryBackend::MergeFavicon() for each bookmark favicon on startup.
This CL stops HistoryBackend::MergeFavicon() from updating the "last updated
time" when MergeFavicon() is called with the same bitmap data as already stored
in the database (no new bitmap data).

This also requires that the class-dump.gyp file move from the

This CL is dedicated to fix above issue and achieve below behaviors:
1.  User Menu does not close during sign-in flow: Things can't steal focus; the user menu stays open while you're typing / in the signin flow.
2.  Sign-in confirmation is modal: The user menu is not closeable until the user interacts with the signin confirmation window.  Sync should be delayed until the user interacts with the dialogue.
3.  Blue information box: This shouldn't go away until the user explicitly interacts with it (not you, what's new, "x").  Doesn't affect modality/close-ability of the user menu.

The "LocalDelta" version of ScrollLayer in LTHI takes a scroll delta in
viewport space and scrolls a layer in its local space. This means that
the delta is scaled so that the scroll appears to be the same distance
on the user's screen, regardless of the page scale factor (pinch-zoom).
This method returns the amount consumed so that the caller can determine
how much of the original scroll delta remains to bubble. However, the
returned consumed delta is in local space, meaning we were subtracting a
layer space delta from the viewport space delta.

The practical effect of this was that when the page was scaled up the
bubbling logic in the viewport would inappropriately bubble up scrolls to
the inner (visual) viewport since the local delta is divided by the page
scale factor. This caused position:fixed elements to "paralax" scroll
with the page, cool looking but incorrect.

Currently TabCapturePerformanceTest records the time between "Capture"
events to determine the rate of capture. These events are issued whenever
a capture is requested, even if it is later aborted, and doesn't represent
the actual capture framerate. This CL adds an event on capture
success which will provide a more accurate idea of capture framerate.

Revert of Change WebContents::last_active_time_ to Time instead of Timeticks. (patchset #1 id:140001 of https://codereview.chromium.org/1140083004/)

Reason for revert:
Reverting for georgesak@ (his committer access hasn't propagated yet it looks like).

After discussion with sky@, decided to keep TimeTicks.

Original issue's description:
> Change WebContents::last_active_time_ to Time instead of Timeticks.
>
> For context, last_active_time_ is going to be used by session restore to order the loading of background tabs using MRU. In order for this to be robust, last_active_time_ must be saved and restore between sessions. Timeticks cannot be reliably restored as it's dependent on the current OS session. MRU code for session restore is being implemented in https://codereview.chromium.org/1131373003
>
> Notes:
> - In dev tools, replaced "activity" with "active" for consistency
> - In OomPriorityManagerTest.Comparator, initialized last_active_time for all tabs, as this is necessary with Time (a default TimeTicks can go back in time, not the case with Time).

"gn path" finds all unique paths. This can be slow because, for example,
//chrome/browser has 478 million unique paths through it's dependency tree
and running path from //chrome/browser to //chrome/renderer took about 6.5
seconds on my big desktop to analyze all of these (to find no results).

This patch keeps track of which targets have been eliminated from consideration
and avoids visiting them again. This improves the above qwuery to 0.78 seconds
while still being able to compute the total number of results.
