This fixes a bug where a bullet character (U+25CF) becomes tofu when it
is a fallback for a webfont and italic style. The fallback font
(Helvetica) has a glyph for U+25CF, but its italic variation (Helvetica
Oblique) does not. In such a case, we should use synthetic oblique.

- Basically, this CL replaces V8AbstractEventListener::m_world with V8AbstractEventListener::m_scriptState.

- This CL uses the ScriptState in a lot of places about event listeners and cleans up the code (for example, this CL removes an empty creation context from toV8()).

- The complicated part is that V8LazyEventListener does not know the ScriptState when it's created. Thus, V8AbstractEventListener::m_scriptState can be null if the listener is a V8LazyEventListener until the V8LazyEventListener is called back from Blink (i.e., either of handleEvent(), callListenerFunction() and getEventListener() is called).

- This CL changes web-exposed behavior. In a case where the frame that registered an onload event handler (say Frame1) is different from the frame that triggers the onload event (Frame2), before this CL, the onload event handler is invoked in the context of Frame2. After this CL, the onload event handler is not triggered if Frame1 != Frame2. This behavior is not speced but aligns with Firefox. See comment #17 and #19 for more details.

I fixed these tests in https://src.chromium.org/viewvc/chrome?view=rev&revision=273996 .

Original Description:

Initializing |v8::Context| is a heavy operation, and should be avoided if necessary. This is meant to be delayed until first time |toV8Context| is called, but |ScriptController::updateDocument| was forcing creation.

This patch fixes the if branch so that it would not create a |v8::Context| if it does not exist.

Right now when it exceeds the appengine storage limit for a single

ideal. Ideally we'd create a new entry but link it to the old
one so we can show it correctly in the UI, but that's too much work.

I accidentally already landed part of this support
in an earlier change, but this makes --upload actually
work.  You can see an example change here:
https://codereview.chromium.org/308743011/

This also adds a hack-and-slash version of sheriff-calendar
code which I and Eric Boren originally wrote for the AutoRollBot
but that lives in a different repository:
https://chromium.googlesource.com/chromium/tools/build/+/master/scripts/tools/blink_roller/auto_roll.py

This combined with a cron job should make
it easy for gardeners to keep FlakyTests up to date.

Looking at 308743011, we clearly need to address some
of this marauding flakiness as FlakyTests should be
a very stable file.  Right now it is changing by the hour.

Prior to this CL, we computed RenderLayer::isUnclippedDescendant in a separate
O(n^2) walk of the out-of-flow RenderLayers. On workloads like famo.us, this
walk is quite expensive because everything is out-of-flow positioned, and
O(n^2) is large.

After this CL, we compute this information as we walk down the tree in the
CompositingPropertyUpdater, which means we can compute the information in
linear time and we can entirely remove the separate tree walk. Moving this
computation also lets us rip out a large amount of machinery that existed to
prune the extra tree walk that this CL removes.

Now that we compute this information with the CompositingPropertyUpdater,
we compute it even when composited overflow scrolling is off.  This confused
some tests that used Internals to poke this state.  I've added a workaround to
keep theses tests working identically.  I'll remove the work around and update
the tests in the next CL.

CSS 2.1 (http://www.w3.org/TR/CSS2/visudet.html#leading) says: "Empty inline 
elements generate empty inline boxes, but these boxes still have margins, padding, 
borders and a line height, and thus influence [line-height calculation] just 
like elements with content."

We weren't creating lineboxes for empty inline elements when they occurred
between a single trailing space and a single leading space - this is because
our linebox creation was based on the too-narrow premise that we were already
ignoring spaces. However, if an empty inline element comes after a trailing 
space but before one or more leading spaces then it will be ignored as part 
of the collapsed space between the trailing space and the next non-collapsible 
space - so we should force the creation of a linebox in such cases.
