When an app is moved to background, onTrimMemory() will be called, and LruBitmapPool/MemoryCache will be trimmed. However, the app could keep running and bitmaps will be retired to MemoryCache and LruBitmapPool. This change allows limit of the sizes of LruBitmapPool/MemoryCache (by MemoryCategory) when the app is in background, and restore the sizes to normal when it's moved out of background.

When an app is moved to background, onTrimMemory() will be called, and LruBitmapPool/MemoryCache will be trimmed. However, the app could keep running and bitmaps will be retired to MemoryCache and LruBitmapPool. In many cases, the amount of memory due to the retired bitmaps in cache is non-trivial.
