b1bbd72e84 net: fix tail size calculation in Ethernet_frame
The const-variant of the data() method contained an erroneous
calculation of the tail size. This led to the size guard throwing
exceptions when trying to parse TCP packets that only contained the
TCP header.

162ddb1fdb virtio: fix len calculation
Thanks to Piotr Tworek for the fix and his explanation as follows:

The basic idea is to try to fit payload data into the descriptor used to
send the header. If there is no payload, or the payload fits exactly
into the remaining space in the header decriptor, len should be 0 and
only one descriptor should be used. In such case the "next" and "flags"
members of the descriptor structure should be set to 0.

In case there is some extra payload data to send, but its size is
bigger than the remaining free space in the descriptor used to send the
header, len should contain the remaining size of the payload that
can't be sent via the header descriptor. The code will then chain
additional descriptors to handle this remainder.

With the len variable shadowing, the code will never queue the remaining
data.

Share datastructures for clock, power and reset related configurations

132e4fe815 platform_drv(arm): robust re-configuration support
This change of the inner working of the platform driver for ARM allows
clients to have permanent open sessions, as long as a policy node matches
the client. If devices disappear from the policy resp. from the set of
available devices (hotplug), the devices ROM of the session gets updated,
and a corresponding device session gets closed. If the device remains
untouched in the configuration but other devices appeared/disappeared, the
device session is not affected.

13dab699b1 base: invalidate entire range on VM-session detach
The requested guest-physical memory range may comprise multiple attached
dataspace regions, which must all be detached. This is not required for
the current vbox5 implementation, but for vbox6 as the current API
suggests these semantics.

This commit can be seen as intermediate fix as a real fix should change
the API to prevent long-running detach loops in core that may lock out
requests by other components.

45cebd774d cpu_balancer: avoid dynamic policy allocation
Pre-allocate all possible type of policy objects as part of the thread meta
state to avoid increased memory consumption due to different policy object
sizes. The cpu_balancer accounts the memory per client and can't forward
potentially occurring out-of-ram exceptions during config-ROM update phases.

1f58b05255 cpu_balancer: limit mem increase on config update
The commits avoids reading in and allocating memory for all potentially
threads, which are potentially currently not existent (but configured in the
policy beforehand). Instead the policy is read in and evaluated when a thread
is created and policy changes are solely applied to existing/running threads.
By this the commit avoids the increase of memory consumption during the
evaluation of policies during config ROM updates.

30b3ad218f virt_qemu: Use VirtIO fb driver instead of ramfb.

7c1888644a os: Add VirtIO framebuffer driver.
This implements the necessary bits to provide 2D framebuffer support on
top of VirtIO GPU device as implemented in Qemu. I don't know if any
other implementation of this specific device exists.

Compared to the ramfb driver which already exists in Genode Virtio FB driver
has one major benefit. It allows Qemu window to be dynamically resized at
runtime. The driver will treat this as resolution change and act accordingly.
Ramfb driver can currently only use the hardcoded 1024x768 screen size. Changing
screen resolution might not sound like a big deal, but it is rather useful to
run Genode on Qemu in full screen mode.

2ec9e69fd4 os: Add support for reading VirtIO responses.
Some more advanced devices like VirtIO GPU do expect they can receive
responses to VirtIO commands they issue via VirtIO queue. Such responses
are not sent via a separate device writeable queue. Instead the driver
is expected to queue some additional descriptors and buffers which the
device can then use to provide the reply.

This patch adds support for such write-data-read-response opeartion to
Genode VirtIO::Queue implementation. The implementation is pretty simple
and does not support any fancy features like receiving the response
asynchronously. Instead the operation will use caller provided callback
to wait for the device to process the command. Once this callback
returns the write-data-read-response VirtIO::Queue function will invoke
another callback passing received response as argument.

dc39a8db62 base: introduce Allocator::try_alloc
This patch changes the 'Allocator' interface to the use of 'Attempt'
return values instead of using exceptions for propagating errors.

To largely uphold compatibility with components using the original
exception-based interface - in particluar use cases where an 'Allocator'
is passed to the 'new' operator - the traditional 'alloc' is still
supported. But it existes merely as a wrapper around the new
'try_alloc'.

9591e6caee vbox6: CPU halt/wakeup via RTSEMEVENTMULTI
The former use of Pthread conditionals did not cover the corner case of
early wakeups just before halting the CPU. These wakeups were simply
lost which resulted in sporadic halts of about 500 ms (the maximum timeout
of all halts in VirtualBox). RTSEMEVENTMULTI preserves early wakeups
and effectively prevents the CPU from halting.

Additionally, we now wakeup the target CPU on VMMR0_DO_GVMM_SCHED_POLL
and, thus, mimic the behavior of the original implementation slightly
better,
