We have to correct the CC_OPT_* variable for these files and used to do so via
phony pre-requisite for the corresponding object files because the correction
had to take place after the variable initialization in
import-lx_emul_common.inc and before the creation of the object files. However,
this caused the objects to always rebuild.
This commit fixes this issue by using Make's feature of target-specific
variables instead. The drawback of this solution is that we can no longer
override CC_OPT_* with a modification of its original value but instead have to
override with a completely new value. This is because otherwise, Make would
either complain about recursive assignment or produce an empty value.
Ref #4519
The strict conversion warnings were disabled during development when the
contrib code was still compiled with the wireguard lib. Now this isn't
necessary anymore as the contrib code is in the wireguard_lx_inc_dirs lib.
Ref #4520
Introduce an arch-specific wireguard lib that contains all code from the
former arch-specific target.mk files. This allows us to create a generic
target.mk that merely depends on the library and a dummy.cc file. The latter
ensures that building/linking of the target isn't skipped by the build system.
Ref #4519
The wireguard library's purpose is having a separate INC_DIR setting for the
files that need Linux include paths that would clash with Genode include paths.
Therefore, the name wireguard_lx_inc_dirs is more descriptive. Furthermore,
this allows us to create a new arch-specific wireguard lib in a future commit
in the course of preventing arch-specific target.mk's (a commonly used
approach in Genode).
Ref #4519
A userland component that ports the Linux WireGuard kernel module (originally
from kernel version 5.14.21) and integrates it via a NIC session (public
network side) and an Uplink session (private network side). The
WireGuard-specific device configuration is done through the component
configuration. The port is done using lx_emul, lx_kit and the virt_linux
targets. The commit adds also 4 corresponding run scripts of which 3 are fully
automated of which 1 is added to the autopilot.
:Warning:
Although in principal functioning, the WireGuard port has not been exposed to a
sufficient amount of real-world testing, so far. Therefore, we strongly
recommend not to use it in any security-critical scenarios! There is no
guarantee that the port meets any of the security goals pursued by the
WireGuard protocol or other WireGuard implementations!

The location of the used 'source.list' file is hard-coded and will not
work when the ported driver is implemented as a shared library. For
this use-case provide means to set the location differently.
Issue #4455.
.SHELLFLAGS is extended by option pipefail to make pipes fail if any pipe
element fails. As .SHELLFLAGS is exported into sub-make instances it
must be unexported before calling third-party build systems recursively.
To support device-less protocol-stacks only ports, we can use a
Virt I/O Linux kernel flavor, and export the lx_kit/lx_emul parts
not depending on platform API and devices.
Ref #4397
* Drivers have to use lx_kit/memory_dma.cc
* Protocol-stacks use lx_kit/memory_non_dma.cc
* Moreover the device-dependent lx_emul parts get removed
from the common lx_emul import rules
Fix#4443
We use the architecture-specific setjmp/longjmp implementation without
modification in the newer lx_kit implementation as well. There is no
need for a duplication.

In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".
Ref #3961
Thise driver supports USB LTE modems for Huawais' ME906s through MBIM
and provides a traditional Nic session. The "control" interface is a
Terminal session, which can be used via libmbim/mbimcli.
issue #3822
By now, the enumeration of peripheral interrupts on Raspberry Pi 1 was
different in between base-hw kernel and Fiasco.OC. Therefore, hacks were
needed in every driver to request the correct interrupt number dependent
on the kernel. Before reproducing the same in the platform driver for rpi,
we can more easily use the same enumeration with base-hw.

* Make package buildable for ARM too
* Move usb library to src targets for explicitly named targets
* adapt remaining run-scripts to use the correctly named usb drivers
Ref #2190
According to the creator of the net-stat lib, this lib was a mere debugging
tool that is not used anymore nor worth the work of updating the it to
modern Genode coding paradigms. Also, there exist no tests for the lib.
