Instead of having a generic "virt_qemu" board use "virt_qemu_<arch>" in
order to have a clean distinction between boards. Current supported
boards are "virt_qemu_arm_v7a", "virt_qemu_arm_v8a", and
"virt_qemu_riscv".

On okl4, pistachio, sel4 the test didn't come up fast enough in order to still
experience the first configuration of NIC router #1. This commit doubles the
lifetime of the first configuration of NIC router #1 to 4 seconds and raises
the overall test timeout accordingly.
Ref #4555
Instead of returning an invalid device capability when a device
is (not yet) available, e.g. a PCI device is requested before the
PCI bus got parsed accordingly, we check the device capability
within the Platform::Connection utilities, and register temporarily
an Io_signal_handler to wait for changes of the devices ROM, and
try the device aquisition again. Thereby, simple drivers so not have
to take the burden to do so.
To enable this feature for all drivers, we always have to export a
devices ROM, but limit the information about physical resources
(I/O memory addresses, IRQ numbers, I/O port ranges) to clients with
'info=yes' in their policy description.

By adding a 'report' node to the platform driver's configuration
one can enable either devices or config reports. The devices
report contains all devices and their detailed state, as well as
whether it is already in use or not. The config report contains
one by one the current configuration of the platform driver.
Moreover, this commit adds a README file describing the facilities
of the platform driver.

* Test DHCP RENEW by the test client in the unmanaged variant.
* Add event IDs to log output of test client in order to prevent false positive
result in the managed variant.
* Let managed and unmanaged variant have separate string patterns for
'run_genode_until' because they already had different output and it will
differ even more as we don't want to test DHCP RENEW with the managed
variant.
* Delay first test client DHCP in order to fix unexpected sporadic initial IP
config.
* Remove some unnecessary code from the run script

The functionality of the test-block-client, test-block-server, and
test-block-bench components is now covered by the block_tester
application and the vfs_block server.
Issue #4405
Since the change "block_tester: limit batching in sequential test", the
sequence test blocks infinitely when encountering a length value smaller
than the block size.
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.
Issue #4333
With this commit, the NIC router DHCP client reads out the first DNS domain
name (DHCP option 15) if any from a DHCP reply that generates an IPv4 config
for a domain and stores the name together with the IPv4 config for that domain.
DNS domain names are reported via the new report tag '<dns-domain>' if the
'config' attribute in the config tag '<report>' is set.
Furthermore, the NIC router DHCP server becomes able to obtain a DNS domain
name from another domain that has a DHCP client dynamically (given the config
attribute 'dns_config_from' is set and no static DNS config is given) or
statically from its configuration (new config tag '<dns-domain>') and propagate
this name with DHCP replies (DHCP option 15).
The 'nic_router_dhcp_*' tests are adapted to test the new feautures.
The commit also gets rid of some mirrored files in
'test/nic_router_dhcp/manager'.

WARNING: BREAKS CONFIG COMPATIBILITY!
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!
How to adjust:
At each occurrence of the 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.
DETAILED DESCRIPTION
The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.
Ref #4246
BREAKS CONFIG COMPATIBILITY:
This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!
HOW TO ADJUST:
At each occurrence of the '<uplink ...>' tag in a NIC router configuration
replace the tag name 'uplink' with 'nic-client'. The rest of the tag stays the
same.
The term "uplink" for network interfaces in the router that have a NIC session
client as back end was introduced in a time when Uplink sessions didn't yet
exist. Now, they do and, although both an uplink and an Uplink session
normally describe a network session between router and network device driver,
they are based on two different service types (NIC and Uplink). This can easily
cause confusion when integrating the router (the <uplink> is not related to
Uplink sessions) or trying to understand its functioning (an 'Uplink' object
has nothing to do with the Uplink service).
Therefore, this commit introduces the more specific term "NIC client" for an
interface that is based on a NIC session requested by the router. This doesn't
imply any semantic changes at the NIC router. However, the commit also brings a
broader update of the router's README and removes the term "downlink" that was
used only in documentation to refer to interfaces backed by a NIC session
provided by the router. The term was only associated with this meaning because
it is the natural counterpart to an uplink. This isn't appropriate anymore as
the terms for interface types have moved to a more technical level.
The commit adjusts all scenarios in the basic Genode repositories properly.

The test script failed during preparation of the on-target execution for
USB Armory with the following error:
! can't read "tz_vmm_block_irq": no such variable
Presumably, the script wasn't run anymore since the introduction of the
'tz_vmm_block_irq' variable for i.MX53 QSB. As we do not have infrastructure
for automated testing of the USB Armory and there seems to be not much
interest in using Genode on this platform, this commit simply removes the
support from the script.
Filtering boards in a run script by specs isn't the right way anymore (the
specs do not exist anymore). Nowadays, we have to use [have_board] instead.
Ref #4229
For unknown reasons, the former 'wget genode.org' call, that was meant to test
network in the Trustzone guest on imx53_qsb_tz, didn't succeed anymore although
the same call succeeded on my Sculpt VM Linux. However, 'ping 1.1.1.1' still
works, so, the script now uses this as test for networking instead.
Fixes#4229
When Interface::handle_config_3 (third step of applying a new configuration to
interfaces) tried to detach the interface from the current IP config because
the old and new IP config differed, it did so using the new domain. The former
steps of the reconfiguration already installed the new domain reference at the
interface. Therefore, also the DHCP server of the new domain was used. This,
however caused uncaught exceptions because detaching from an IP config
includes dissolving all DHCP allocations. This dissolving of DHCP allocations
now operated on a DHCP server (the one of the new domain) that wasn't related
to the allocations and, in the worst case, caused an uncaught exception
because the IPs were out of its range.
That said, this commit ensures that detaching an interface from an IP config
is always done on the domain from which the IP config originated. Normally,
this is the domain the interface is attached to. But in the case of
Interface::handle_config_3, it is another - the former domain the interface
was attached to.
The commit also adapts the nic_router_dhcp_* tests in a way that they
reconfigure the router in a way that would trigger the uncaught exception
without the fix.

This new runscript demonstrates how a file can be overwritten by vfs
import with the flag overwrite set to false. This is due to a bug
in lx_fs that is not propagating an ernno EEXIST syscall error.

* The device XML information dataspace is only provided,
when the client's policy states `info="yes"`
* The device XM information gets changed to include the
physical resource names (I/O memory and IRQ addresses)
instead of virtual ids and page offset
Fix#4077
This patch adds the missing destruction of session-state objects of
local services when closing a session. Because of the missing
destruction, those session-state object remained part of the server
ID space. This becomes a problem once the backing store of the session
state object vanishes, that is when the client child gets removed from
the sandbox. Hence, the removal of a child with an open session to a
local service would lead to the corruption of the server ID space.
This patch adds the missing session.destroy() call.
Fixes#4044
This way, the redirected env sessions for the CPU burner are no longer
called directly by init. Init stays independent from the behavior of the
CPU balancer.
