Modify WallpaperManager interface as a prototype for Mojo interface

This is not the final version ready for the Mojo interface, but makes
the following modifications:

1) Make the distinction between 'set', 'show', and 'remove':
'set' must be called with a new image or file.
'show' is to actually display the wallpaper 'set' for this user before.
'remove' refers to the process of removing the custom wallpaper that
may be set earlier. When clients call 'RemoveUserWallpaperInfo', what
they need is to remove the wallpaper, so rename to RemoveWallpaper.

2) WallpaperInfo should be an internal concept. Make the related
methods private.

3) 'ShowSigninWallpaper' is a new method. Although the concept of
sign-in wallpaper is not new. It's reasonable to separate it from
ShowUserWallpaper because it's a different use case.

cros: Create WallpaperControllerClient to replace WallpaperManager

The functions listed in the mojo interface are all from
WallpaperManager. The next step is to move their implementation to
//ash one by one. By the time they are all moved, WallpaperManager
can basically be deleted.

wallpaper refactoring: Move SetOnlineWallpaper to WallpaperController

Migrate |SetOnlineWallpaper| (used by wallpaper picker) to
WallpaperController.

The goal of the CL:

1) Make sure not to introduce regression in |WallpaperManager| under
Config::CLASSIC. (Have to use some 'hacks' within |WallpaperManager| to
avoid forking the code.)

2) MASH does not crash when setting wallpaper, but it won't be able
to save wallpaper. The wallpaper newly set during an active session
will be lost when the session ends.

wallpaper refactoring: Move RemoveUserWallpaper to WallpaperController

All the temporary code have been explicitly marked as TODO. Those
without the mark is the 'permanent' code.

1) Replace RemoveUserWallpaper with a mojo call via
   |WallpaperControllerClient|.

2) Add additional directory paths in |SetClient| and rename it to
   |SetClientAndPaths|.

3) Add additional unit tests for |WallpaperController|.

wallpaper refactoring: Move SetCustomWallpaper to WallpaperController

|IsPendingWallpaper()| returns false in three cases: 1) Kiosk mode is
on, 2) Policy is enforced. 3) |show_wallpaper| is false. The first two
cases are now checked by |CanSetCustomWallpaper()|, and case 3) is
the same with |account_id.is_active|.

The check of |CanSetCustomWallpaper()| does not work under MASH. It's
listed as TODO. (Lots of code in arc_wallpaper_service.cc depends on
wallpaper controller observer, so it's actually not working with MASH
right now.)

In addition, after the refactoring, SetCustomWallpaper does not go
through PendingWallpaper any more (PendingWallpaper is only useful
for |ShowWallpaper()|, not custom wallpapers). So there is no need to
keep |IsPendingWallpaper()|.

wallpaper refactoring: Move ShowWallpaper to WallpaperController

1) Migrated everything related to ShowWallpaper except for device
   policy wallpaper. Therefore the WallpaperManager::ShowWallpaper
   method is still kept but it's trivial to completely remove it later.

2) Delete PendingWallpaper. In the unlikely case that it turns out to
   be useful, we can add it back.

3) Deleted the tests which have been disabled for a long time in
   wallpaper_manager_browsertest.cc. Left a TODO for
   |WallpaperControllerTest.ShowCustomWallpaperWithCorrectResolution|
   since it depends on UpdateWallpaper() to be migrated.

wallpaper refactoring: Delete UpdateWallpaper in WallpaperDelegate

Previously, UpdateWallpaper() is needed in the WallpaperDelegate
interface because it relies on Chrome to set the correct image. After
everything is migrated, it no longer needs to call into Chrome.
(Eventually WallpaperDelegate will be deleted as well.)

All the tests in |wallpaper_manager_browsertest.cc| have been migrated
(some of them are deleted because they have been disabled for a long
time). But there is some untested code path in wallpaper_manager and
we'll add more tests in follow-up CLs.

wallpaper refactoring: SetCustomizedDefaultWallpaper

1) Moved the wallpaper_manager.cc code that's only used by customized
   default wallpapers to a separate file under
   //chrome/browser/chromeos/customization. That should be a better
   place than ash/wallpaper.

2) customization_wallpaper_downloader_browsertest.cc already tests this
   code path.

3) Deprecate the |CustomizedWallpaperRescaledFiles| class for
   simplicity.

4) Changed the API to SetCustomizedWallpaperPaths that only sends paths
   instead of images. Previously, several places that called the method
   had to supply empty images as placeholders.

wallpaper refactoring: Reimplement SetPolicyWallpaper

A few differences with the current implementation:

1) Currently there're both |WallpaperManager::OnPolicySet| and
   |OnPolicyFetched|. |OnPolicySet| merely labels the wallpaper
   as POLICY type to prevent potential wallpaper changes. This results
   in a temporary inconsistency between the actual wallpaper and its
   type. In this version this method is deleted. (ie, if policy fetch
   never succeeds, WallpaperController won't know about the policy.)

2) Currently |OnPolicyCleared| only sets the type back to DEFAULT
   without deleting the policy wallpaper file. This doesn't result in
   visible bugs, but it's better to delete the files and explicitly
   calls SetDefaultWallpaper for this user.

3) The existing tests in wallpaper_manager_policy_browsertest.cc stay
   unchanged in this CL. But they may be moved to a different place
   later.

Test: Verified on Admin console, no conflict with device policy.

cros: Move InitializeWallpaper to WallpaperControllerClient

We should be able to deprecate InitializeWallpaper after views-based
login is enabled: the call sites should request the wallpaper at login
screen or after chrome restart. Currently, both InitializeWallpaper and
the call sites request the same wallpaper resulting in duplicate logic.

InitializeWallpaper is still useful at login screen because the web-ui
has a delay in loading, so InitializeWallpaper will first show a
wallpaper to fill the gap. But the views-based login should be fast
enough so InitializeWallpaper is unncessary.

commit 45db4d022a57c54f5f2ae40a7a95f314c56ef099
Author: Wenzhao Zang <wzang@chromium.org>

cros: Move |ShouldShowInitialAnimation| to WallpaperController

We can completely deprecate the WallpaperDelegate interface after this
CL.

Created |OnFirstWallpaperAnimationFinished| to support a code path in
web-ui login. We should be able to delete it after views-based login is
enabled.
