This patch ultimatedly removes format strings from Genode's base API.
Users of the former base/snprintf.h and base/console.h headers may
use the free-standing 'format' library hosted in the ports repository.

Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.
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".
issue #4034
The parent-provides model is destroyed if no <parent-provides> node is
found in the configuration, which resulted in
Warning: list model not empty at destruction time
and leaking memory for the allocated nodes. The commit now explicitly
empties the list model in the destructor of ~Parent_provides_model.
Note, the case is implicitly tested in pkg/test-init by step "denial of
forwarded session request" and <init_config version="empty">.
Thanks to Peter for reporting this issue.
Fixes#4547
The Uplink_test used to end in an uncaucht exception about a failed packet
allocation on several x86_32 platforms.
* Destruct and re-construct the corresponding TX packet allocator during a
link-down-up step in the Uplink test. Fixes the exceptions but results in a
never ending test.
* Decouple the link-down-up steps from the handling of packet stream signals
by simply triggering it with a local periodic timeout of 1 sec period.
This prevents that the Uplink_test never finishes because it destructs the
Uplink connection too often.
* The test finishes not before at least 3 link-down-up steps were executed.
* Replace the Allocator_avl's used for the TX packet allocators of the Nic
and Uplink Connection with the better suited Nic::Packet_allocator.
Ref #4419
The service is merely announced but trying to request a session always causes a
Service_denied exception. This helps in scenarios where the client is
won't open a session anyway but expects the service to be available. This is
considered a temporary solution.
Ref #4419
This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:
- Add 'trace_logger' to the 'launcher:' list of the .sculpt file
- Either manually select the 'trace_logger' from the '+' menu,
or add the following entry to the deploy configuration:
<start name="trace_logger"/>
By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.
Issue #4448
This patch changes the output format of the trace logger to become
better suitable for human consumption. For example, when instrumenting
the VFS server in Sculpt using the GENODE_TRACE_TSC utility, the
trace logger now generates tabular output as follows.

Subjects that belong to the same PD are grouped together. The formerly
optional affinity and activity options have been removed. Those
information are now unconditionally displayed. The trace entries
belonging to a thread appear as slightly indented.
The patch also updates the coding style, avoiding excessively long
lines.
Issue #4448
* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
Fixgenodelabs/genode#4416
* Creates sessions to all supported services of the black hole component
* Test-drives the Event and Capture session with dummy input
* Adds the test to the default list of depot_autopilot.run
* Test-driving the Audio_in and Audio_out sessions is still missing and should
be added via a dedicated commit
Ref #4419
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.
