Add MemoryTransfer interfaces to the wire

Browse Source 
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.
