f186587cab
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. Issue #1832

|
* 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).
