Implement additional IGraphicBufferProducer transactions
The following GraphicBufferProducer transactions were implemented: * `SetBufferCount` * `DetachBuffer` * `DetachNextBuffer` * `AttachBuffer` It should be noted that `preallocatedBufferCount` (previously `hasBufferCount`) and `activeSlotCount` were adapted accordingly with how they were effectively the same value as all active buffers were preallocated prior but now there can be a non-preallocated active slot. Additionally, a bug has been fixed where `SetPreallocatedBuffer` has the graphic buffer as an optional argument whereas it was treated as a mandatory argument prior and could lead to a SEGFAULT if an application were to not pass in a buffer.
