WallpaperCropper: respect max wallpaper width

Some devices with high resolution screen only support 2048px wide
wallpaper (used to be fixed in I5b25bd931db0b2610e260921f28b92d8b0966aa6)

Pre-KitKat this works as follows:

- Launcher calls WallpaperManager.suggestDesiredDimensions and we
  limit the maximum size in that function
- The wallpaper setting application calls WallpaperManager
  .getDesiredMinimumWidth and respects that size

However, after KitKat, it is all broken because WallpaperCropper
now calculate its own dimension and does respect the value set by
getDesiredMinimumWidth (and it calls suggestDesiredDimensions,
which is supposed to be reserved for Launchers!)

Attempting to restore wallpaper setting by:

- Having WallpaperCropper respect config_wallpaperMaxWidth
- Having CMWallpaper (which copy pasted code from WallpaperCropper)
  respect getDesiredMinimumWidth
- For third party applications, if they respect getDesiredMinimumWidth,
  then they will work, but if they don't (i.e. uses WallpaperCropper's
  code), then there's nothing we can do.

Volumes in Settings/Sound is slow to start

There is a delay after pressing volume menu item
there is a delay until the Volume popup is shown.

The reason for this is that the initialization of
the different seekbars is slow and run in the main
thread. More specifically the call to get the
ringtone from the RingtoneManager is causing this
delay.

Moving the call to the ringtone manager to the
handler thread used to play ringtones to make
the launch of the volume dialog a bit snappier.
