ike-auth: Calculate and collect IntAuth for IKE_INTERMEDIATE exchanges
...
The message ID of the first IKE_AUTH exchange is a safe-guard against
potential truncation attacks if IKE_INTERMEDIATE exchanges are not used
for multiple key exchanges but some other future use where the number of
exchanges might not depend on the selected proposal.

We currently only support these exchanges for additional key exchanges,
so once we have the final keys derived and the ike-init task is removed,
we don't expect any more of them.

kernel-netlink: Set replay window 0 if kernel supports SA direction attribute
...
The kernel now allows a 0 replay window with ESN for SAs that are
explicitly tagged as outbound SAs. But not just that, it actually
rejects outbound SAs with replay windows > 0. So we add a version check
to control the replay window size. Note that adding the attribute
unconditionally would be fine even for older kernels, but if somebody
backports the direction patches, the installation of outbound SAs might
fail if the replay window is not adjusted accordingly.

android: Add workaround for a bug preventing background service starts from TileService
...
When targeting Android 14, we get a "Background activity launch blocked!"
exception when trying to start the connection in the background (closing
the drawer works). Which is apparently a bug:
https://issuetracker.google.com/issues/305035828
The workaround here is kinda ugly. In particular, because it's not
possible anymore since a few versions to open a dialog that allows users
to directly grant the required permission to the app. We can only open
the generic settings dialog where users have to search for the app and
grant the permission themselves (we could add a dialog with an explanation
similar to the one for the power whitelist if necessary). Hopefully this
gets fixed at some point (the current beta of Android 15 still has the
same bug, though).
