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.
