'_env_ram' allocations can lead to
'Expanding_pd_session_client::try_alloc' quota upgrades, which in turn
may lead to a resource request by the platform driver. Therefore, we
check the available quota within the platform driver before allocations.
This is not an optimal solution.

This patch makes the component graph better reusable for the phone
version of Sculpt. In the phone version, the '+' menu does not exist.
So we need to omit the corresponding button. Furthermore, the storage
dialog is presented in a dedicate section of the GUI instead of
presenting it inside the 'storage' graph node. The phone version
also does not offer the inspect view. So we need to omit the
corresponding buttons.
To prevent caching side-effects of USB DMA memory taken from the packet stream
all allocations of USB packets need to be on separated cachelines at least.

To complement the GPIO support allow for setting and reading input
pins. So far this is needed by drivers that attempt to perform I2C
bit-banging via GPIO pins.
Fixes#4624.
In case the allocation fails for the largest possible connector mode,
try smaller modes. Additional add option to specify maximal resolution.

Increase "assumed" internal kernel memory size based on available memory
to support allocation of framebuffer larger than 16M, which was before
hardcoded.
Issue #4659
When using the newer genode_c_api uplink library, an uplink connection uses
the device name as label, which enables integrators to use different policies
resp. routes for different devices driven by one driver. The nic_drv policy
of the nic_roouter configuration generated by the sculpt_manager however uses
an empty label like: "nic_drv -> ". This is the way how existent NIC drivers,
like ipxe_nic_drv requested their uplink session. To support both driver
variants this commit relaxes the policy by checking for a prefix only.

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.

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.

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.
