This patch adds MemoryTransfer client/server interfaces and uses it to implement data transfers for buffer mapping. This patch also provides a default "inline" implementation of the MemoryTransfer which is used if the embedder does not provide one on initialization. Because implementations of MemoryTransfer perform their own serialization, a skip_serialize option is added to WireCmd records.
