This patch handles margins in line height quirks[1] as defined in
the spec. Edge and Gecko don't do this, but Blink and WebKit do,
and there are wpt tests.

Child process is blocked until it receives the invitation, but sending
it requires a hop to the client thread. Renderers are started from the
UI thread on Android, and the UI thread can be busy with other tasks,
delaying renderer initialization.

This CL separates sending Mojo invitation from other child process
notification tasks, and sends the invitation from the launcher thread.

Previously, DialogOverlayCore didn't receive a release() call from
DSImpl, since DSImpl drops the reference to DSCore immediately
after notifying the client of surface destruction.  This caused
problems on some cast devices, where the overlay wasn't being
deleted properly.

Now, DSCore calls release() synchronously after waiting for
DSImpl to close the overlay.  This keeps the dismiss() call sync
with respect to onSurfaceDestroyed.  Even if DSImpl did call
DSCore.release(), it would be after onSurfaceDestroyed completed.

In OSX 10.10+, some combination of the titlebar and
toolbar always show in fullscreen mode. We do not want
either to show so we hide the window that contains these
views. This way, only our custom toolbar will show on

However, this cause an issue where the titlebar
disappears for windows without our custom toolbar
(Ex/ Chrome app windows and popups). This CL adds a check
so that that we only hide the window if it has a toolbar.

Now that DialogOverlayImpl destroys the overlay when the WebContents

We want UKM scroll latency reporting to work for --enable-viz (i.e. for the
case when display compositor is in the GPU process). This means that we need to
report these metrics in LatencyTracker::ReportUkmScrollLatency, not in
RWHLatencyTrcker::ReportUkmScrollLatency.

This CL adds ukm::SourceId to LatencyInfo. The source id is set on the
LatencyInfo object in RWHLatencyTracker::OnInputEvent. This way LatencyTracker
(which does not have access to RWHDelegate) can use the ukm::SourceId from
LatencyInfo when reporting UKM scroll latency.
