a903049a1a cli_monitor: Resource-balancing support 
This patch introduces new commands for dynamically balancing RAM between
subsystems. The 'status' command prints a table with the RAM status of
each subsystem. The 'ram' command changes the quota or a quota limit of
a given subsystem. The quota limit can be defined to allow the on-demand
expansion of the quota. Finally, the 'yield' command can be used to
instruct a subsystem to yield a specified amount of resources.

For trying out the new commands, a so-called 'ram_eater' example has
been added to the 'terminal_mux.run' scenario. This program simulates a
subsystem with a growing demand for resources, yet with the capability
to yield resources when instructed by the parent (i.e., cli_monitor).

Besides implementing the new features, the patch splits the
implementation of 'cli_monitor' into multiple files.

cbdad73dd7 terminal_mux.run: LOG output of terminal_log 
This patch tweaks the route of 'terminal_log' such that a LOG session
request of this program is directed to the parent rather to itself.

9cf677cb0a os: Add resource balancing-support to 'Slave' 
In order to be able to dynamically balance resources of slaves, we need
to provide an accessor to the slave's RAM session and a way to issue
yield requests.

90aa4ef6b5 core: Don't account RAM metadata to RAM quota 
The meta data for allocations should be accounted to the session quota
instead of the RAM accont managed by the session.

5befab7f3d Add 'String<SIZE>' buffer type to 'util/string.h' 
The new 'String' buffer type is meant to replace the manually created
character buffers that are scattered throughout Genode. It plainly holds
a null-terminated string to be stored as a member variable (e.g., a
session label) or passed as RPC argument. It is not intended to become a
string API.
