Adds Genode::Hex_dump class to the formatted_output.h header. This class can be
used to print a hexadecimal dump of a byte range. The data is printed in a
format similar to that used by Linux's 'xxd'. In addition to the 'xxd' format,
consecutive duplicate lines are replaced with a single "*\n" as done also by
Linux's 'hexdump'.

The DHCP client implementations of Ping originally is a copy of the NIC router
implementation adapted for Ping. The two versions diverged further over the
years. This issue should be solved by should merging them into a centralized
implementation. However, this commit treats only a recent issue with the
nic_uplink.run test on pbxa9 qemu but does this by re-aligning the two
implementations partially. The final merge should be done in a separate commit.
Ref #4966
* Removes the <event> tag from all test package runtime files and replaces the
contained <timeout> and <log> sub-tags with the new tags <succeed> and
<fail>. If a <succeed> or <fail> tag has a content, it defines a log pattern
that should be recognized and render the test failed or successful. If a
<succeed> or <fail> tag has an attribute after_seconds that is not set to 0,
it defines a timeout after which the test should be rendered failed or
successful.
* Adapts the Depot Autopilot to support the new syntax in the test-package
runtime files. However, for now, the Depot Autopilot is kept compatible to
the old syntax as well. If the <events> tag is present, it is prioritized
over the new syntax.
Fixes#4922
Several nightly network-related tests fail currently on sel4/pc because the
new e1000 NIC driver requires more capabilities. The "drivers nic" package
was already adapted to the new requirement but some tests fail to provide
enough caps to the corresponding sub system. This commit tries to fix all
remaining tests.
Ref #4923
* Adds a new component server/nic_uplink that forwards packets unmodified
between one Uplink session at one side and potentially multiple Nic sessions
at the other side.
* Adds a new run script nic_uplink.run that does a basic test with multiple
Nic clients on this component and adds it to the autopilot list.
* Adds a new depot recipe src/nic_uplink for this component.
* Adds a new depot recipe pkg/pc_nic for deploying the pc_nic_driver together
with a nic_uplink server. This allows for raw access to the network connected
to the Nic of the system in contrast to the commonly used routed and NAT'd
access via NIC router. That said, it enables the use of network protocols
not yet supported by the NIC router at the cost of less protection.
Ref #4966
Introduces a new class that does the clean-up if some exception is
thrown while creating the session. This reduces redundancy and overall
lines of code.

by just test the migration feature, without relying on load measured on the
CPUs. On Qemu (and depending on other load in the Linux system), the migration
feature gets not triggered in time reliable.
This change allows a monitored VBox instance to specify a distinct
(lower) priority to the VM session to ensure that the VMM is always
prioritized higher than the VCPUs. This is important because host
I/O at the VMM should always be able to preempt a busy guest.
Issue #4917
The memory barriers where introduced with commit "test-timeout: fix build
errors with -std=gnu++20" presumably in order to prevent GCC optimization from
removing the empty for loops the test is using because using a volatile index
variable was no longer an option.
However, the memory barriers seem to have a negative effect on the measurements
performed with the affected loops. The commit caused the timeout test to fail
at least on imx53_qsb.
This commit fixes the issue by using a simple empty for loop without volatiles
or memory barriers but protected inside a function that is compiled with
optimization disabled.
Ref #4959
* add a sensible priority setup into the test script in order to protect
drivers and stack components from the demanding net clients
* delay the starting of the net clients by 5 seconds in order to give the
drivers and stack components some time to startup in peace
* use only explicit service routing and caps values

Nitpicker's hover and focus reports contain an 'active' attribute, which
can be inspected for the detection of user activity, e.g., as trigger
for a screensaver or for dynamic clipboard policies.
When using the 'Event' session, the reporting code updated the reports
only on incoming events. This patch adds the periodic reporting as used
when using the old 'Input' session.
Issue #4950
While this approach still scans "holes" in the bus range, it stops
scanning at the maximum subordinate bus number reachable from the base
PCI bus at the host bridge. Startup under Qemu no longer takes about 12
seconds for scanning 256 buses.
On some platforms (x86_32/pistachio, x86_64/sel4) system startup is slow
and the previously configured 30 seconds not sufficient. With this commit, the
timeout is raised to 60 seconds only when running on such a platform.
Ref #4923
This test was originally a copy of ping.run and therefore unnecessarily
inherited all its complexity for testing ping component behavior. Additionally,
ping.run was more actively maintained and evolved over time whereas
nic_dump.run didn't receive the same care. Now, the test fails on certain
platforms although NIC dump works just fine. Therefore, this commit reduces the
test behavior to what is really necessary for testing nic_dump and by doing so,
also fixes the failing targets.
Fixes#4926
On x86_32 okl4, the test timed out although the test timeout was already at
240 seconds for this platform. Instaed of raising it further, this commit
reduces the number of ping rounds for all platforms that are considered as
slower by the test.
Ref #4923
The new monitor component at os/src/monitor is the designated successor
of the gdb_monitor. This initial version, however, implements only the
subset needed to inspect the memory of the monitored component(s).
In contrast to the gdb_monitor, the new component supports the monitoring
of multiple components, leveraging the sandbox API. It can therefore be
used as a drop-in replacement for the init component. Like the gdb_monitor,
the new monitor speaks the GDB protocol over Genode's terminal session.
But the protocol implementation does not re-use any gdbserver code,
sidestepping the complexities of POSIX.
There exist two run scripts illustrating the new component. The
os/run/monitor.run script exercises memory inspection via the 'm' command
by letting a test program monitor itself. The os/run/monitor_gdb.run
script allows for the interactive use of GDB to interact with monitored
components.
Issue #4917
Let the sandbox library disregard all unknown config sub nodes so that
supplemental information - like the monitor policy configuration - is
not interpreted as a misconfiguration ("unknown config element type ...").
Issue #4917
By default, the sandbox uses the Env::pd() as reference PD session of
the sandbox children.
However, to accomodate use cases where the interplay of the reference
PD session and the child's address space needs to be intercepted, this
patch adds a constructor that takes an interface for the controlled
access of PD intrinsics as argument.
