This patch equips the pin-driver framework with support for the
time-multiplexed operation of a pin as output or input. This is needed
when implementing I2C communication via a bit-banging driver.
To operate pin in both directions, a driver obtains both a pin-state and
a pin-control session for the same pin. The pin-state session can be
used to sense the current pin state. The control session allows the
client to set the pin to high or low (using the 'state' method), or to
set it to high-impedance via the 'yield' method. Once switched to
high-impedance, the pin can be used as input.

The tar.gz archive of version 2.4.9 vanished from sourceforge. As the
project moves to GitHub currently and the archive of 2.4.9 is still
available there, just update the download location.
Content and hashes did not change.
If a device should not be reset, powered off, and its clocks
shall stay untouched when it gets released, the leave_operational
attribute can be set to true in the device node of the related
device inside the devices ROM delivered to the platform driver.
This is useful for drivers, which only enable and initialize
their device, and can be closed afterwards.

To enable other irqchip declarations beyond the lx_emul generic code base,
make the ARM specific initialization routine public.

With "grub2: update to newer grub2 2.06 version" a regression slipped in
which makes the ISO not bootable on real hardware. The commit reverts to
the previous behaviour, to load the GRUB2 modules after boot later one by
one in the ISO format case.

Reintroduce:
USB Attached SCSI devices might expose a bulk-only interface
as fall-back at interface 0 and alternate setting 0. This commit
allows for probing all alternate settings of the active interface
to be able to use such devices.
The configuration was extended so that in case the device interface
is known beforehand the driver can be configured accordingly.
Additionally:
Perform configuration reset upon sessions close in order to bring USB
device to a well defined state.

The NOVA kernel and Genode's roottask core are configured to be runnable
with up to 64 CPUs (MAX_SUPPORTED_CPUS in core resp. NUM_CPU in kernel).
On machines with more CPUs a reset occurred. The commit checks for this
case, bootstraps the first 64 CPUs only, and sends all other CPUs to
sleep.
Also, the platform_info ROM size is increased to host information about
more than 32 CPUs.
Issue #4640
If `select_from_ports` is evaluated lazily, we might miss a port during
the dependency check. A way to prevent this is to use the `:=` operator.

Implement the guest code in dedicated assembler source file, assemble
and link the binary to vmm_x86. The resulting guest-code binary
populates one page that is mapped to host the reset vector of the guest.
This approach simplifies future guest code adaption resp. extension,
e.g., to test rdmsr/wrmsr exiting.

plain_decorator_theme.tar is not linked to the app but must be generated
as side effect. Therefore, use CUSTOM_TARGET_DEPS to trigger the
generation.

This reverts commit 9a37ccfe29 except for the
new declarations in public headers (in order to not change any APIs again).
We revert the commit as we found that there are corner cases in which it
produces a bad UDP checksum. The bad UDP checksum was observed via Wireshark at
a TFTP server in a Sculpt 22.10 Debian 11 VM on the first request of fetching a
file with the TFTP client of the uboot on our iMX8 test board.

According to OpenBSD's azalia driver some AMD HDAudio devices do not
play nice with MSIs although the capability is set. At least the
0x1457 device was tested and worked using GSIs only.

During initialization _handle_link_state may be called concurrently from EMT and
"nic_ep" (signal handler). Therefore, sent signal to "nic_ep" instead of calling
_handle_link_state from EMT thread.
issue #4632
Some DHCP clients (Debian VM in Sculpt) persistently store the last lease they
obtained and try to directly DHCP REQUEST it on a new startup whithout doing
DHCP DISCOVER beforehand. In case the NIC router doesn't know about the lease
anymore (timeout, new router instance), the router used to just ignore the DHCP
REQUEST. This led to significant delays in the network startup of the client
(delayed retries until give-up and DHCP DISCOVER). With this commit, the router
answers such packets with a DHCP NAK instead, causing the client to directly
switch to DHCP DISCOVER.
Fixes#4634
This patch removes the intermediate querying of the depot while the
installation of packages is in progress. This avoids misleading warning
messages and reduces superfluous file-system load during the
installation of large packages.
Issue #4631
On-demand initialization prevents read-write operations on BARs of
invalid devices at construction time, which may result in surprising
behavior later on, for example, when resetting X260 notebooks via ACPI
information.
These utilities simplify the control of clocks, resets, and power
domains from within the platform driver.
This is needed when driving a low-level device directly from the
platform driver, for example for driving the mbox mechanism to access
the system-control processor of the PinePhone.
This patch reflects both the pci_decode results and the platform
driver's aggregated device information in Sculpt's /report/drivers/ in
the form of pci_devices and devices files respectively.
