e9525f49fd noux: reflect -no memory- case during process setup
Instead of just red messages in the log and a hanging caller, the issuer
may respond to it - e.g. a noux bash shell will show an error and is
afterwards still usable.

c9272937e7 CPU session: apply quota via relative weightings
Physical CPU quota was previously given to a thread on construction only
by directly specifying a percentage of the quota of the according CPU
session. Now, a new thread is given a weighting that can be any value.
The physical counter-value of such a weighting depends on the weightings
of the other threads at the CPU session. Thus, the physical quota of all
threads of a CPU session must be updated when a weighting is added or
removed. This is each time the session creates or destroys a thread.

This commit also adapts the "cpu_quota" test in base-hw accordingly.

af2cd7175c vbox: enable video acceleration (VBVA)
This commit enables the VirtualBox graphics adapter, provides guest mouse
pointer integration with Nitpicker using the 'vbox_pointer' application
and enhances the VirtualBox run scripts with the configuration of
Nitpicker, input merger and network driver.

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.

5d06078d27 x86 vmm: add general multiprocessor support
* repos/ports/include/vmm
 - add support to specify cpu location during vCPU construction
* seoul
 - update to latest seoul branch supporting smp
 - adjust to vmm interface changes
 - vCPUs will be put in a round robin fashion on the available host CPUs,
   beginning with the next CPU after the default (boot) CPU
 - number of vCPUs can be specified in run script
* virtualbox
 - adjust to vmm interface changes
 - uses still one vCPU, placed on default (boot) CPU
