BUG: 18386625

Original description:

This is a small webview-specific workaround that affects all drivers.
Will need a better driver/version specific workaround later.

Change-Id: Iec566f9f166397a104badb8b549cc59e6173faac

* changes:
  Update volantis workaround to cover L mr0.1
  Cherry-pick: Workaround NVidia eglWaitSyncKHR bug
  Cherry-pick: gpu: Use egl client wait if server wait not available

This patch fixes a regression from K to L. Tapping the back button
while in fullscreen should exit fullscreen instead of the current
activity.

Clean cherry-pick from

Android platform provides a local proxy that also handles PAC proxy
resolution. The CL below modified enabled chrome network stack to start
using V8 proxy resolution on Android platform:
https://codereview.chromium.org/573013002/
however webview cannot use V8 proxy resolution since Webview is significantly
different from chrome: Webview is single process vs. chrome is multithreaded
and use of V8 isolates creates concurrency problems with Blink's use of V8
isolates.
For now, we want to establish the prior behavior for android webview and
consider making changes to v8 proxy resolver in future.

Bug: 18297802

Cherry-pick disable channel id

Android webview does not use channel id since there is no API
to share channel ids and this would break some apps that use
different network stacks. This change is to explicitly
disable it.

BUG: 18283959

Original description:

Chromium shares a message loop with Android on the browser UI thread.
This can cause problems when the associated Looper has a sync barrier,
preventing posted Chromium tasks from being dispatched until the
barrier is removed. Make this sharing more fair by marking all Chromium
Message tasks as asynchronous, avoiding stalls when there is a sync
barrier.

Note: This change was originally landed in crrev.com/512333002, but was
reverted to gather more data about sync barrier impact and investigate
alternative solutions. The investigation determiend that this approach
is fine for the near future, though it will likely evolve in time.

Cherry-pick: Revert of [Android] Experimental sync barrier detection for tracing (patchset #6 id:100001 of https://codereview.chromium.org/575103002/)

BUG: 18283959

Original description:

Reason for revert:
Barrier detection is no longer necessary, see crrev.com/512333002.

Original issue's description:
> [Android] Experimental sync barrier detection for tracing
>
> When an Android View is invalidated outside of frame dispatch
> (animation/input/draw), a sync barrier may be inserted into the shared
> UI thread message loop. This effectively blocks dispatch of all Chrome
> tasks posted to the browser UI thread for an entire frame (or more if
> the View is continually invalidated).
>
> There are currently no easy or even automated ways to avoid this
> untimely invalidation, and judicious coding can only take us so far. As
> an intermediate assist in debugging the issue, use reflection and a
> crude form of MessageQueue inspection to trace known cases where the
> MessageQueue is blocked by a sync barrier.
>
> Note that this detection is not perfect, neither is it exact, but it's a
> solid proxy for informing traces about such pipeline stalls.

detached

Bug: 18373995

Original Description:

PopupWindows are used to render text handles in WebView. As these popups
are drawn outside of the web contents View hierarchy, it's possible that
their visibility becomes unsynchronized with the WebView itself. For
example, after the WebView has been detached from the window but
before it has been properly disposed of. Address this by overriding
handle visibility when the (content) View is detached, restoring it
only after re-attachment.

Clear the selected text when hiding the handles and the desired
behavior is to "unselect all on dismiss".

BUG: 17965814

Original description:

Previously, there was a hack/optimization where when shrinking a pile,
there would be no invalidations.  Unfortunately, this hack's time has
come due.  When zooming out, recorded pixels outside of the pile's newly
shrunken bounds can get used, causing pixels from old frames to get
incorrectly sampled, causing bogus hairlines.

To fix this, issue invalidations for previously exposed content in the
same way that invalidations are currently issues for newly exposed
content.

Bug: 18066784

Original change description:

Previously, selection handles would be hidden when the content view
became unfocused. This approach worked fine in Chrome, where the focus
model is predictable, but led to undesirable consequences in WebView,
e.g., the handles never being shown. For now, avoid making any kind of
visibility changes to the handles when the focus changes, ensuring
handle visibility is consistent with the selection.

Also ensure timely cleanup of the PopupTouchHandleDrawable Java object
after its native counterpart has been destroyed.

Bug: 18066784

Original change description:

If the ContentViewCore container view is not focusable (which can
happen when it's emebedded in an app via android webview), we
were clearing the RWHVA notion of focus when the RenderView was
swapped out. As the view is never focusable again, chromium never
considers this view focused and as such, text selection did not
function.

We support this type of container view by always treating it focused
from Chromium's point of view.

The size update races with the page load creating the opportunity
for the page to observe the initial (0,0) renderer size. This patch
addresses the issue by sending the initial size together with the
RenderView creation request.
