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.

This is just the interface. The implementation is still missing.

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.
