ikev2: Only add NAT-D notifies to DPDs as initiator
If a responder is natted it will usually be a static NAT (unless it's a
mediated connection) in which case adding these notifies makes not much
sense (if the initiator's NAT mapping had changed the responder wouldn't
be able to reach it anyway). It's also problematic as some clients refuse
to respond to DPDs if they contain such notifies.

pkcs11: Look for the CKA_ID of the cert if it doesn't match the subjectKeyId
charon-nm fails to find the private key when its CKA_ID doesn't match the
subjectKeyIdentifier of the X.509 certificate. In such cases, the private
key builder now falls back to enumerating all the certificates, looking for
one that matches the supplied subjectKeyIdentifier. It then uses the CKA_ID
of that certificate to find the corresponding private key.
It effectively means that PKCS#11 tokens where the only identifier to relate
the certificate, the public key, and the private key is the CKA_ID are now
supported by charon-nm.

Merge branch 'ikev1-rekey-deletion'
Sends a DELETE when rekeyed IKE_SAs are deleted. This fixes issues with
peers (e.g. Cisco) that continue to send DPDs on the old SA and then
delete all SAs if no response is received. But since the DELETE could get
dropped this might not fix the issue in all cases.
Also, when terminating an IKE_SA DELETES for all CHILD_SAs are now sent
before sending one for the IKE_SA and destroying it.

ikev1: Send DELETE for rekeyed IKE_SAs
If we silently delete the IKE_SA the other peer might still use it even
if only to send DPDs. If we don't answer to DPDs that might result in the
deletion of the new IKE_SA too.
This is the minimum size an IPv6 implementation must support. This makes
it the default for IPv4 too, which presumably is also generally routable
(otherwise, setting this to 0 falls back to the minimum of 576 for IPv4).
bus: Fix maximum log levels when mixing log/vlog implementing loggers
The maximum would not get set correctly when a logger is removed and the
first remaining logger in the list (the one with the highest log level) does
e.g. only implement vlog() while there are other loggers that implement log().
This would result in only max_vlevel getting set correctly while max_level
would incorrectly get set to -1 so that log() would not get called for any
of the loggers anymore.

kernel-netlink: Pass zero mark to kernel if mask is set
The kernel will apply the mask to the mark on the packet and then
compare it to the configured mark. So to match only unmarked packets we
have to be able to set 0/0xffffffff.
kernel-netlink: Support configuring XFRM policy hashing thresholds
If the number of flows over a gateway exceeds the flow cache size of the Linux
kernel, policy lookup gets very expensive. Policies covering more than a single
address don't get hash-indexed by default, which results in wasting most of
the cycles in xfrm_policy_lookup_bytype() and its xfrm_policy_match() use.
Starting with several hundred policies the overhead gets inacceptable.
Starting with Linux 3.18, Linux can hash the first n-bit of a policy subnet
to perform indexed lookup. With correctly chosen netbits, this can completely
eliminate the performance impact of policy lookups, freeing the resources
for ESP crypto.
WARNING: Due to a bug in kernels 3.19 through 4.7, the kernel crashes with a
NULL pointer dereference if a socket policy is installed while hash thresholds
are changed. And because the hashtable rebuild triggered by the threshold
change that causes this is scheduled it might also happen if the socket
policies are seemingly installed after setting the thresholds.
The fix for this bug - 6916fb3b10b3 ("xfrm: Ignore socket policies when
rebuilding hash tables") - is included since 4.8 (and might get backported).
As a workaround `charon.plugins.kernel-netlink.port_bypass` may be enabled
to replace the socket policies that allow IKE traffic with port specific
bypass policies.
This makes the FWD policies in the out direction optional (disabled by
default). They may be enabled (e.g. if conflicting drop policies are
used) via the policies_fwd_out swanctl.conf option.

child-sa: Only install outbound FWD policies if explicitly configured
They are only required if drop policies would otherwise prevent
forwarding traffic. This reduces the number of policies and avoids
conflicts e.g. with SPD hash thresholds.
In case an external thread calls into our code and logs messages, a thread
object is allocated that will never be released. Even if we try to clean
up the object via thread value destructor there is no guarantee that the
thread actually terminates before we check for leaks, which seems to be the
case for the Ada Tasking threads.
leak-detective: Whitelist some glib/libsoup functions
Some of these are pretty broad, so maybe an alternative option is to
not use the soup plugin in the openssl-ikev2/rw-suite-b* scenarios. But
the plugin is not tested anywhere else so lets go with this for now.
When fresh CRLs are released with a high update frequency (e.g.
every 24 hours) or OCSP is used then the certificate cache gets
quickly filled with stale CRLs or OCSP responses. The new VICI
flush-certs command allows to flush e.g. cached CRLs or OCSP
responses only. Without the type argument all kind of certificates
(e.g. also received end entity and intermediate CA certificates)
are purged.
This might be helpful to get the complete picture of the installed
rules. `-c` is currently not used as the counters that are added in
front of every rule make the output quite hard to read and the counters
are already provided in the accompanying `iptables -v -L` output.

ikev2: (Re-)Queue tasks used to establish an IKE_SA in reset()
Some tasks might get removed immediately once the IKE_SA_INIT response has
been handled even if there were notifies that require a restart of the
IKE_SA (e.g. COOKIE or INVALID_KE_PAYLOAD). Such a task is ike_vendor,
which caused vendor IDs not to get sent in a retry. This change ensures
all required tasks are queued after the reset, which some callers did
already anyway.
