Most of the code (if not all) was landed in 
 https://codereview.chromium.org/1084923002
 https://codereview.chromium.org/1393203004
so I'm adding the author. For reference, ITI 
is in [1], bug in http://crbug.com/257511

alogvinov@, is this reshuffling OK with you? 
How come this feature is still behind a flag?

https://groups.google.com/a/chromium.org/forum/#!topic/blink-dev/Yujx917y6-Y

Yes it's OK with me. I think exposing the feature without the flag requires an intent to ship, am I right? The spec itself is still in the Public Working Draft status, so I'm not sure if the feature should be behind the flag or not.

#2: Yes, it'd need at ITS. Thanks for the clarification.

[OnionSoup] Moving WakeLock Service to Blink (2/2): removing WebWakeLockClient and WakeLockDispatcher

This CL is part 2/2 of moving the WakeLockService renderer parts
from content/ to WebKit/. The complete transfer can be found in
https://crrev.com/1794553002, of which this is the part removing
the WebWakeLockClient and its renderer implementation. See bug
for more info.

This CL removes the files
 - content/renderer/wake_lock/wake_lock_dispatcher.*
 - WebKit/Source/platform/wake_lock/WebWakeLockClient.h

since that functionality is folded into
  WebKit/public/platform/modules/wake_lock/ScreenWakeLock.*
of which some methods are made private.

modified to talk directly to the mojo service impl in
browser's render frame host.

The WebKit unittests ScreenWakeLockTest.cpp:
- is refactored to use a MockServiceRegistry and a
mojo MockWakeLockService.
- is NOT moved out of web/ because it needs a couple
of Test infra located there. This unit test should be
made into a (series of) LayoutTests, but that's beyond this CL.

BUG= 600895 

TESTS= in particular:
./out/Debug/webkit_unit_tests  --gtest_filter=*ScreenWakeLockTest.*
./out/Debug/content_browsertests --gtest_filter=WakeLockTest.*

The bug is mostly closed, but had to leave 
ScreenWakeLockTest.cpp in web/tests due to 
dependencies. Now that we have mojo, I'd 
rather move those tests to LayoutTests.

Renaming Blink>Architecture to Blink>Internals

Marking this as Fixed and tracking the follow-up work to
nuke WebKit/Source/web/tests/ScreenWakeLockTest.cpp in
