8f9355b360 thread API & CPU session: accounting of CPU quota
In the init configuration one can configure the donation of CPU time via
'resource' tags that have the attribute 'name' set to "CPU" and the
attribute 'quantum' set to the percentage of CPU quota that init shall
donate. The pattern is the same as when donating RAM quota.

! <start name="test">
!   <resource name="CPU" quantum="75"/>
! </start>

This would cause init to try donating 75% of its CPU quota to the child
"test".  Init and core do not preserve CPU quota for their own
requirements by default as it is done with RAM quota.

The CPU quota that a process owns can be applied through the thread
constructor. The constructor has been enhanced by an argument that
indicates the percentage of the programs CPU quota that shall be granted
to the new thread. So 'Thread(33, "test")' would cause the backing CPU
session to try to grant 33% of the programs CPU quota to the thread
"test". By now, the CPU quota of a thread can't be altered after
construction. Constructing a thread with CPU quota 0 doesn't mean the
thread gets never scheduled but that the thread has no guaranty to receive
CPU time. Such threads have to live with excess CPU time.

Threads that already existed in the official repositories of Genode were
adapted in the way that they receive a quota of 0.

This commit also provides a run test 'cpu_quota' in base-hw (the only
kernel that applies the CPU-quota scheme currently). The test basically
runs three threads with different physical CPU quota. The threads simply
count for 30 seconds each and the test then checks wether the counter
values relate to the CPU-quota distribution.

4eda2deeb1 ddekit: remove sleep_forever in dde_kit_debug
The way this function is currently used in dde_linux expects this
function to return. Since there is dde_kit_panic it should better
be used in such a case the output should block.

e4c636b0a0 init: clamp priority values to valid range
This patch ensures that priority values passed as session arguments
are within the valid range of priorities. Without the clamping, a child
could specify a priority of a lower priority band than the one assigned
to the subsystem. Thanks to Johannes Schlatow for reporting this issue.

35239b84df dde_kit: remove jiffies alias
The alias is rather Linux-specific and also prevents particularly
tailored jiffies implementations. For the existing dde_linux ports (usb
and lxip) we just define jiffies to be dde_kit_timer_ticks with a
preprocessor macro.

08d28e9b94 nitpicker: add 'session_control' RPC function

cases where one texture is applied to both a pixel surface and an alpha
channel.

46968c0015 nitpicker: motion events for non-xray clients
When X-ray mode is active, nitpicker filters motion events that are not
referring to the currently focused domain. However, domains configured
as xray="no" (such as a panel) need to obtain motion events regardless
of the xray mode. This patch relaxes the motion-event filtering to
accommodate such clients.

83705d3c78 nitpicker: fix input-mask offset calculation
The buffer offset was wrongly accounted for. The miscalculation went

23c22f52b3 nitpicker: consider xray config in find_view
If a domain is configured as xray="no", we want to let the views of the
domain respond to input events like in flat mode, even if xray mode is
active. Normally, the input mask of views with an alpha channel is
disregarded in X-ray mode. However, for non-ray views, the input mask
should always be considered.

81af714949 Input merger
This component merges the input events of multiple sources.

Example configuration:

<start name="input_merger">
	<resource name="RAM" quantum="1M" />
	<provides>
		<service name="Input" />
	</provides>
	<config>
		<input label="ps2" />
		<input label="usb_hid" />
	</config>
	<route>
		<service name="Input">
			<if-arg key="label" value="ps2" /> <child name="ps2_drv" />
		</service>
		<service name="Input">
			<if-arg key="label" value="usb_hid" /> <child name="usb_drv" />
		</service>
		<any-service> <parent /> <any-child /> </any-service>
	</route>
</start>

For each 'input' config node, the component opens an 'Input' session with the
configured label. This label is then evaluated by 'init' to route the session
request to a specific input source component.

Fixes #1259.

e9032904a3 Increase slab-block size in signal component
The backend allocator for the slab is a sliced heap, which hands out
allocations with page-size granularity (4096 bytes). Therefore, the
slab-block size should also be about a multiple of the page size minus
some bytes of overhead.

Additional adjustments:

- The slab-block size and the default quota-upgrade amount for SIGNAL
  sessions depends on the platform bit width now.
- The signal test also stresses the case of many managed context in one
  session including creation and destruction of the used signal receiver
  in repeated rounds.
