This allows switching to probing mode if the client is on a public IP
and this is the active task and connectivity gets restored. We only add
NAT-D payloads if we are currently behind a NAT (to detect changed NAT
mappings), a MOBIKE update that might follow will add them in case we
move behind a NAT.
This is quite helpful to debug why a pattern didn't match.
As it could produce quite a lot of output if something is not found in a
log file, the complete output is only printed in verbose mode, otherwise,
`head` is used to print the first 10 lines of output.
We only get stdout from SSH, so the stderr redirection is only really
for errors ssh itself produces.
Allow charon to start as a non-root user without CAP_CHOWN and still be
able to change the group on files that need to be accessed by charon
after capabilities have been dropped. This requires the user charon starts
as to have access to socket/pidfile directory as well as belong to the
group that charon will run as after dropping capabilities.

Stater will lose update/reload commands when there is a second signal
coming in when the previous is still processed. This can happen more
easily with big configurations.
Closesstrongswan/strongswan#101.
In case the PRF's set_key() or allocate_bytes() method failed, skeyseed
was not initialized and the chunk_clear() call later caused a crash.
This could have happened with OpenSSL in FIPS mode when MD5 was
negotiated (and test vectors were not checked, in which case the PRF
couldn't be instantiated as the test vectors would have failed).
MD5 is not included in the default proposal anymore since 5.6.1, so
with recent versions this could only happen with configs that are not
valid in FIPS mode anyway.
Fixes: CVE-2018-10811
We continue to parse them but remove the documentation because mixing the two
sets of keywords in the same config might result in unexpected behavior.

Adds new options to force the local destruction of an IKE_SA (after
trying to send a DELETE first). This might be useful in situations where
it's known the other end is not reachable or already deleted the IKE_SA so
there is no point in retransmitting the DELETE and waiting for a response.
