When reconfiguring the NIC router modifies the information that DHCP clients
received through a DHCP server of the NIC router, the link state of the
correspodning interface has to do a "down-up" sequence. This provides a signal
to the DHCP clients to redo DHCP, receive the new information and update
accordingly.

* Introduce CPU quota for driver subsytem (needed by sd_card_drv)
* Introduce CPU quota for runtime subsytem and nic_drv (needed by fec_nic_drv)
* Increase CAP quota for inspect terminal slightly
* Add sculpt packages for imx8q_evk
Fix#3958
Updating the config and using its settings instead of only reporting
the new session allows to apply stored channel settings immediately.
In case of Sculpt this is useful when an existing launcher already
contains a valid config that sets the volume levels appropiately or
the 'recall_fs' is used.
Fixes#3930.
When compiling this code, clang complains reference to 'Sandbox' is
ambiguous. It can either mean ::Sandbox namespace from
os/src/lib/sandbox/types.h, or Genode::Sandbox declared in
repos/os/include/os/sandbox.h. Since the code refers to ::Sandbox::Child
and its already in ::Sandbox namespace we can just drop "Sandbox" and
refer to just Child, which makes clang happy.

* Fix semantic of SGIR register for GICv2
* Minor GIC model IRQ state fix
* Introduce synchronization for VirtIO and GIC models
* Enable multiple CPUs in test run-script for ARMv8
Fix#3926
The driver is faily simple and does not support fancy features like
TCP checksum offloading or vlan filtering, but it is fully capable of
running every Genode network based scenario I've tried. Its currently
known to work on virt_qemu arm platforms and x86_64.
Fix#3825
To simplify writing native VirtIO drivers for Genode add helper classes
representing VirtIO device and queue. The queue implementation should
be platform independant. The device abstraction however is closely tied
to the VirtIO transport being used (PCI/MMIO). Both PCI and MMIO
implementations expose the same public API so the actual driver logic
should be the same regardless of which transport is used.
Its also important to note that the PCI version of Virtio::Device
currently does not support MSI-X interrupts. Unfortunately my kowledge
about PCI bus is very limited and my main area of interest was to get
VirtIO drivers working on virt_qemu ARM/Aarch64 platform. As such all
the VirtIO drivers I plan to submit will work with PCI bus, but might
not use some extended capabilities.
Ref #3825
The VirtIO device configuration on Qemu is dynamic. The
order and presence of different command line switches affects
base address and interrupt assignment of each device. One could
probably hard-code the necessary switches and resulting XML ARM
platform driver configuration in each run script, but this seems
like troublesome and hard to maintain solution.
This patch explores an alternative approach to the problem.
It implements a ROM driver which probes the address space region
Qemu virt machines assign to VirtIO MMIO devices and exposes the
result as XML via a ROM session. This XML output can be fed directly
as config to the generic ARM platform driver.
Ref #3825
Right now the same code dealing with nic setup on qemu is duplicated
in many different run scripts. It makes it unnecesarily complex to
change the existing config or add support for new nic types. Lets move
all this common code to qemu.inc.

- make GPIO server more robust on imx by not throwing exceptions for
unknown pins, use '_with_gpio' instead
- use 'Gpio::Pin' data type instead of POD 'unsigned'
issue #3900
The patch handles the case, that the memory for the MSI-X table is part
of one of the Pci::Resource Memory BARs, which got allocated beforehand already.
With this commit, the platform driver will not fall back to use legacy IRQs or MSI, whereby MSI-X is available actually. Additionally, this patch avoids a lot of red
messages about non available IO-MEM printed by the roottask.

Fixes#3884
This patch fixes the corner case where the keyboard focus is defined
independently from user interactivity, e.g., the activation of a
screensaver or lock screen.
In this case, nitpicker would update its internal focus state not before
the next input event is handled. Should this input event be a press
event, this event would wrongly be delivered to the prior focused
session. Another problematic situation is the initial state before the
very first input event occurs. Since the focus remains undefined until
the first input event is handled, an initial key press event would not
be delivered.
This is a regression caused be the transition to the event-session
interface and the removal of the nitpicker's periodic way of operation.
The patch fixes the problem by applying pending focus changes not only
at the input processing but also on the code path that responds to focus
changes (e.g., focus-rom update).
Issue #3812
Instead of using the old 'ioctl' Vfs::File_io_services API implement
the I/O control functionality in a buch of files. This is similar to
the terminal-VFS plugin.
Fixes#3889.
The combination of Net::Mac_address and
Genode::ascii_to(Net::Mac_address) required shaky quirks in several
places because GCC is not able to resolve the ascii_to overload if
base/xml_node.h was included to early. The current solution moves the
several ascii_to overloads "closer" to the Net types by putting them
into the Net namespace, where GCC reliably picks them up.
Hence, co-locating the ascii_to() utility with the overload type in the
same scope/namespace is good practice.
This patch removes the now obsolete <nic/xml_node.h> header file.
