This was from a student project that has never been developed further.
And similar to the manager web application it lacks all sorts of modern
standards. So just remove it and the two plugins it relied on.
The test scenario is renamed to avoid confusion (neither of the two
p2pnat scenarios uses medsrv/medcli).
The plugin was apparently broken for years because it uses functions that
don't exist anymore. It was quite limited anyway, so it was never really
used in OpenWrt to begin with (instead they generate configs in a custom
init script).
This also refactors the BPF handling so it can be shared between the
dhcp and farp plugins. The latter is adapted accordingly.

This makes sure the event is only triggered after the IKE_SA is fully
established and e.g. virtual IPs, additional peer addresses or
a modified reauth time (on the initiator) are assigned to it. This was
e.g. a problem for the selinux plugin if virtual IPs are used.
We use a separate task to trigger the event that's queued before the
child-create task so the event is triggered before the child_updown()
event. Same goes for the state change to IKE_ESTABLISHED.
A new condition is used to indicate the successful completion of all
authentication rounds, so we don't have to set the IKE_ESTABLISHED state
in the ike-auth task (it was used as condition in other tasks).
Since set_state() also sets the rekey and reauth times, this required
some minor changes in regards to how AUTH_LIFETIME notifies are handled.
After establishing an IKE_SA, we check if any of its child configs
define generic SELinux labels and install trap policies for them if
necessary narrowed to the current (virtual) IPs.
This allows us to use it without having to initialize libcharon, which
was required for the logging (we probably could have included debug.h
instead of daemon.h to workaround that but this seems more correct).
This is similar to the eap-aka-3gpp2 plugin. K (optionally concatenated
with OPc) may be configured as binary EAP secret in ipsec.secrets or
swanctl.conf.
Based on a patch by Thomas Strangert.
Fixes#2326.
Unfortunately, we can't just add the generated C file to the sources in
Makefile.am as the linker would remove that object file when it notices
that no symbol in it is ever referenced. So we include it in the file
that contains the library initialization, which will definitely be
referenced by the executable.
This allows building an almost stand-alone static version of e.g. charon
when building with `--enable-monolithic --enable-static --disable-shared`
(without `--disable-shared` libtool will only build a version that links
the libraries dynamically). External libraries (e.g. gmp or openssl) are
not linked statically this way, though.
On failure the SA is deleted and reestablished as configured. The task
is activated after the REAUTH_COMPLETE task so a make-before-break reauth
is completed before the new SA might get torn down.
This logger can be used to easily register custom logging instances
using __attribute__((constructor)) benefiting from the global reload
mechanism (with reset of log levels).
Note that this is not intended to be used from plugins, which are loaded
after loggers have already been initialized.

If additional tasks get queued before/while rekeying an IKE_SA, these get
migrated to the new IKE_SA. We previously did not trigger initiation of these
tasks, though, leaving the task unexecuted until a new task gets queued.
While it has some tests that we don't directly cover with the new unit tests,
most of them require special infrastructure and therefore have not been used
for a long time.
To quickly check out IKE_SAs and find associated CHILD_SAs, the
child_sa_manager stores relations between CHILD_SAs and IKE_SAs. It provides
CHILD_SA specific IKE_SA checkout functions wrapping the ike_sa_manager.
