commit c9709c486a33ea3c5c831e3216310259fb9bbba4
Author: Stuart Langley <slangley@chromium.org>

Start the replacement of WTF::WeakPtr with base::WeakPtr.

This CL lays the groundwork for removing WFT::WeakPtr and
replacing it with base::WeakPtr.

Note: WTF::WeakPtr is already just an alias for base::WeakPtr,
so there is no change in functionality. WTF::WeakPtrFactory
wraps base::WeakPtrFactory and is using "USING_FAST_MALLOC"
but I don't see this type being explicitly new'd up, so I don't
think changing to base::WeakPtrFactory is of any consequence.

Changes in the CL:

- Update presubmit script to allow base::WeakPtr &
  base::WeakPtrFactory from blink code.
- Update all the DEPS files to allow "base/memory/weak_ptr.h"
  to be used from blink code.
- Make changes to some files in (core|modules|platform) to use
  base::WeakPtr(Factory) to validate above changes.
- In places remove "platform/wtf/WeakPtr.h" where it's no longer
  used in the file.
- In places where base::WeakPtr was already being used but it
  was transitively included, fix the includes.
- Where we are now using base::WeakPtr(Factory) use base:: to
  lookup the right WeakPtr.

The subsequent CL will remove WTF::WeakPtr. I was going to try and
do it all in 1 CL but it got too big to review.

commit 85cb2f71a50dd7da960d31cd599df1cd9d6487b9
Author: Stuart Langley <slangley@chromium.org>
Date: Sat Dec 02 15:26:15 2017

Remove WTF::WeakPtr entirely and replace it with base::WeakPtr.

This CL deletes platform/wtf/WeakPtr.h and replaces and code
that was still using it in WebKit/ with base::WeakPtr(Factory).

In some cases the file was included but was not needed, so
we just delete the header.
