When we have a "keep" unique policy in place, we have to be less strict in
rejecting Main/Aggressive Modes to enforce it. If the host/port equals to
that of an existing ISAKMP SA, we assume it is a reauthentication attempt
and accept the new SA (to replace the old).
Sending a DELETE for the replaced SA immediately is problematic during
reauthentication, as the peer might have associated the Quick Modes to the
old SA, and also delete them.
With this change the delete for the old ISAKMP SA is usually omitted, as it
is gets implicitly deleted by the reauth.
Enabling FIPS mode twice will fail, so if it is enabled in openssl.conf
it should be disabled in strongswan.conf (or the other way around).
Either way, we should log whether FIPS mode is enabled or not.

A new connection ID allows listeners to track which errors they have
already shown to the user or were already dismissed by the user.
This was necessary because the state fragment is now unregistered from
state changes when it is not shown.
Besides that updates don't make much sense when the fragments are not
displayed this fixes the following exception:
java.lang.IllegalStateException: Can not perform this action after
onSaveInstanceState
This is especially useful on Android where we are able to send messages
even if we don't know the correct local address (this is possible
because we don't set source addresses in outbound messages). This way
we may learn the correct local address if it e.g. changed right before
reestablishing an SA.
Updating the local address later is tricky without MOBIKE as the
responder might not update the associated IPsec SAs properly.
When using auto=route, current xfrm_acq_expires default value
implies that tunnel can be down for up to 165 seconds, if
other peer rejected first IKE request with an AUTH_FAILED or
NO_PROPOSAL_CHOSEN error message. These error messages are
completely normal in setups where another application
pushes configuration to both strongSwans without waiting
for acknowledgment that they have updated their configurations.
This patch allows strongswan to override xfrm_acq_expires default
value by setting charon.plugins.kernel-netlink.xfrm_acq_expires in
strongswan.conf.

Adds support to pki --pub to convert public keys to other formats
including SSH keys and DNSKEYs. SSH public keys can also be read
from files in the format used by OpenSSH.
This adds man pages for all pki sub-commands and promotes pki to a
regular program installed in $prefix/bin.
The usage output of several commands was fixed too.
