This patch enhances init with the support for rewriting session labels
in the target node of a matching session route. For example, a Noux
instance may have the following session route for the "home" file
system:
<route>
<service name="File_system" label="home">
<child name="rump_fs"/>
</service>
...
</route>
At the rump_fs file-system server, the label of the file-system session
will appear as "noux -> home". This information may be evaluated by
rump_fs's server-side policy. However, when renaming the noux instance,
we'd need to update this server-side policy.
With the new mechanism, the client's identity can be hidden from the
server. The label could instead represent the role of the client, or a
name of a physical resource. For example, the Noux route could be
changed to this:
<route>
<service name="File_system" label="home">
<child name="rump_fs" label="primary_user"/>
</service>
...
</route>
When the rump_fs receives the session request, it is presented with the
label "primary_user". The fact that the client is "noux" is not taken
into account for the server-side policy selection.

This is the example operating system based on the Genode OS framework: :_Init_: is the first real process in the system. The provided implementation uses a very simple XML parser to read its configuration files. :_Drivers_: The example OS has basic drivers for frame buffer, mouse and keyboard input, the PCI bus, the real-time clock, and system-specific timers. :_Server_: The only server in the example OS is Nitpicker, a minimal-complexity GUI server. :_Test_: are also part of the example OS. You may have a look at the fork bomb as a simple system stress test. :_Ldso_: is the dynamic linker used for loading executables that are linked against shared libraries. :_Lib_: contains libraries used by the components of the OS repository, for example, the alarm framework.
