commit c646c0a69815d1e82fe60c41514f24aacd401882
Author: Mustaq Ahmed <mustaq@google.com>
Date: Fri Oct 20 20:08:30 2017

Added UserActivationState to replace Frame's sticky state.

Also added a content_features entry to switch between the existing (UGI
based) model and the new (user activation based) model for the transient
activation.  We will gradually hook it up for all user APIs in follow-up
CLs.

This CL doesn't change any behavior when the new content feature is
disabled.

commit 21471a3267702e3a851b688fa4fbb2e6f9ec7733
Author: Mustaq Ahmed <mustaq@google.com>
Date: Fri Oct 27 16:28:21 2017

Replaced UGI-state calls with corresponding Frame functions in Blink.

This CL replaces the calls to UGI::ProcessingUserGesture(),
ProcessingUserGestureThreadSafe() and ConsumeUserGesture() with
the corresponding entry-points in Frame to allow switching to User
Activation v2 model.

The changes here are within Blink only, don't modify WebUGI calls.

Added UserActivationV2 support to WebUserGestureIndicator.

Also fixed most of the callers. We have two remaining groups
(extensions/renderer, content/renderer) with 6 refs in total
that still rely on IsProcessingUserGesture(nullptr).  We will
add plumbing for those in a followup CL.

Update media layout tests that rely on stack-allocated activation

These tests assume (current) UserGestureToken like behavior that
the user activation state is gone outside of the triggering event
loop.  UserActivationV2 would change it, fixing the tests
accordingly.

Remove user activation check for autofill provisional save.

The check is needed to avoid password prompt when a user clicks
a link instead of submitting a filled form.  The original condition
was a weak signal to detect click-on-link, and fails with
UserActivationV2 which changes the scope of a user activation.

For records, only one test relied on the original activation check
is PasswordManagerBrowserTestBase.NoPromptIfLinkClicked .
