With bug 792855 we'll be able to debug/profile a single process remotely (Fennec). The goal of this bug is to extend this to support profiling a multi-process system such as B2G. The current design is to have a central debugging server living in the control process. When child processes are spawned they will register to the central debugging server. When a client wants to connect it will initiate the connect with the central server which will multiplex and proxy the messages to the correct child process (content, plugin). With this approach we only need to deal with a single external RDP server.

Moving to the debugger component since this is a core change and will be necessary for debugging B2G as well.
