5d14adebb5 nic_router: find direct rules w/o exceptions
Replaces the former implementation of the 'find_longest_prefix_match' method at
the data structure for direct rules. This method used to return a reference to
the found object and threw an exception if no matching object was found.

The new implementation doesn't return anything and doesn't throw exceptions. It
takes two lambda arguments instead. One for handling the case that a match was
found with a reference to the matching object as argument and another for
handling the case that no object matches.

This way, expensive exception handling can be avoided and object references
stay in a local scope.

1ca2265fd4 pc/wifi: do not execute driver on user stack
The 'with_libc' call at this point is not necessary and could be
harmful as it forces the usage of the user stack for the driver.
All code depending on this distinction should only be executed
from within the pthread.

6e4c3b2fd6 sculpt: support to skip depot archive integration
To not integrate referenced depot packages when building a sculpt image,

88118b133a intel_fb: request copy of Intel opregion
acpica and the Intel display driver tries to use the Intel Opregion
simultaneously on Genode, which is not supported nor wanted for IO_MEM region as
which it is handled.

Attempts to remove the access to the region was not successful, since some
SSDT table contains ACPI AML code which is executed regularly and read/write
the Opregion.

The patch adds support to read in a copy of the Intel Opregion done by the
acpi_drv component. The copy was sufficient to make the Intel display driver
working to find and lookup the Intel VBT (video bios table) information to
setup all connectors on a Fujitsu U7411 docking station.

f4f2b456b6 base-hw: invalidate VM TLB entries in deletion
This commit introduces a hypervisor calling interface. The host kernel can
use it to either switch to a guest VM, or to invalidate the TLB with
regard to a specified VM id.
The VM-specific TLB invalidation is called whenever a VM (Vcpu)
gets destroyed.

d6592ca2cb base-hw: unset deleted PD values in MMU
When a PD gets deleted check whether it is active on the current CPU resp. MMU.
If yes, switch to core/kernel's PD to prevent that invalid page-tables or
address-space IDs are still in use. Moreover, whenever we switch to an idle
thread, we switch to kernel/core's PD too. Thereby, we prevent that vanished
PDs are still active on CPUs different from the one, where the core entrypoint
is active, which does the PD deletion.
This whole scheme is only valid under the assumption that core has only one
entrypoint running on one CPU.

9375e8d010 wireguard: no warning about possible alignm. issue
We locally disable 'address-of-packed-member' warnings because GCC complained
about possible alignment issues when returning a reference to a packed member
as naturally aligned pointer (for some reason only on arm_v8a). We know that
the member is aligned to NETDEV_ALIGN via __attribute__ and that the warning
is therefor unnecessary.

48e396913c wireguard: don't always rebuild device.c/netlink.c
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.

36d2374ff9 wireguard: exit on invalid configurations
With this commit, the WireGuard component exits with a descriptive uncaught
exception on invalid configurations or when the user attempts to re-configure
attributes that are not re-configurable (private_key, listen_port, interface).

This is particularly important when it comes to the not re-configurable private
key. If the component would just ignore the attempt to override the private
key, the user may come to believe that his old (potentially compromised)
private key is not in use anymore.

The fact that the component now exits instead shouldn't be a problem, as the
user would have to restart the component anyway in order to apply the new
attribute values.

The commit also extends the wg_reconfig run script to test that WireGuard
exits on the attempt to re-configure the private key.

560a166613 wireguard: flags value via enum when adding a peer
I used to set the peer flags to 2 when adding a peer but merely because I
observed that value in my reference Linux. I now found that the flag 1<<1 means
'WGPEER_F_REPLACE_ALLOWEDIPS' and is ignored whenever the peer is new. Anyway,
I keep setting the flag but with the clearer enum name because the wg tool is
doing it as well when adding new peers and we want to stay close to how the
original code interacts.

Build description files that feature both an actual target and

of the CUSTOM_TARGET_DEPS is phony, e.g., gems/src/app/menu_view/.
The re-linking of the actual target is of course not desired. By
triggering the creation of CUSTOM_TARGET_DEPS from 'all:' instead of
'$(TARGET)', the specified files do not implicitly become link
dependencies of the target.
