Themes: Only process themes that are applied during boot

Currently, the PackageManagerService will process all themes and
ensure their resources are compiled and available to the system.
This is highly inefficient and can bog the system down when booting.

This patch will only process the themes that are currently applied
durring boot and lets the ThemeService take care of queuing up the
others for processing.   This reduces boot time considerably,
especially when the user has many themes installed.

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.

 * Not sure who to blame, but it's probably themes... :)

framework: Close system windows when performing 'switch to last app' action

This fixes a bug where performing the action while on the recent apps screen
would cause the next attempt to open recent apps require two presses of the
recent apps button (the first press would toggle it closed, rather than open).

It also prevents the switch from being obscured by the notifications shade.

frameworks/base: Fix delay in sending AUDIO_BECOMING_NOISY intent

AUDIO_BECOMING_NOISY intent is sent as background intent which causes
delay in receiving pause event. This delay caused audio leak. By
marking the event as FLAG_RECEIVER_FOREGROUND, this intent is
received sooner by Application.
