/**
 * We use the BufferCache to reduce the overhead of exchanging GraphicBuffers with
 * the server. If we were to simply parcel the GraphicBuffer we would pay two overheads
 *     1. Cost of sending the FD
 *     2. Cost of importing the GraphicBuffer with the mapper in the receiving process.
 * To ease this cost we implement the following scheme of caching buffers to integers,
 * or said-otherwise, naming them with integers. This is the scheme known as slots in
 * the legacy BufferQueue system.
 *     1. When sending Buffers to SurfaceFlinger we look up the Buffer in the cache.
 *     2. If there is a cache-hit we remove the Buffer from the Transaction and instead
 *        send the cached integer.
 *     3. If there is a cache miss, we cache the new buffer and send the integer
 *        along with the Buffer, SurfaceFlinger on it's side creates a new cache
 *        entry, and we use the integer for further communication.
 * A few details about lifetime:
 *     1. The cache evicts by LRU. The server side cache is keyed by BufferCache::getToken
 *        which is per process Unique. The server side cache is larger than the client side
 *        cache so that the server will never evict entries before the client.
 *     2. When the client evicts an entry it notifies the server via an uncacheBuffer
 *        transaction.
 *     3. The client only references the Buffers by ID, and uses buffer->addDeathCallback
 *        to auto-evict destroyed buffers.
