We have classes you can use to receive the packets. See the
GDBRemoteCommunicationServerLLGS class. This is the "LLDB GDB server" class. It
uses classes whose type is:
class NativeBreakpoint;
class NativeBreakpointList;
class NativeProcessProtocol;
class NativeRegisterContext;
class NativeThreadProtocol;
class UnixSignals;
You would subclass these and fill them in similar to what the linux
implementations are doing.

Let me know if the above info makes sense and feel free to ask any questions.
