Norman Feske f186587cab Unify ipc_msgbuf.h across base platforms
Besides unifying the Msgbuf_base classes across all platforms, this
patch merges the Ipc_marshaller functionality into Msgbuf_base, which
leads to several further simplifications. For example, this patch
eventually moves the Native_connection_state and removes all state
from the former Ipc_server to the actual server loop, which not only
makes the flow of control and information much more obvious, but is
also more flexible. I.e., on NOVA, we don't even have the notion of
reply-and-wait. Now, we are no longer forced to pretend otherwise.

* \author Norman Feske
* \date 2016-03-11
*
* On most platforms, the 'Genode::Native_thread' type is private to the
* base framework. However, on NOVA, we make the type publicly available to
* expose the low-level thread-specific capability selectors to user-level
* virtual-machine monitors (Seoul or VirtualBox).
