Derived from the ipsec initd script, with the following changes:
(1) various code improvements, corrections (get rid of left/right
updown scripts, since there's only one), etc;
(2) add reauth and fragmentation parameters;
(3) add x.509 certificate-based authentication;
and other minor changes.

If you shutdown ipsec service, and it doesn't clean up
/var/ipsec/ipsec.conf, then when you start swanctl service it
might see an incompatible file on startup. Remedy is to
remove unneeded files when shutting down the service. They
can always be regenerated when the service starts again.

These config files are only used by the ipsec interface to charon,
and shouldn't be part of the base package.

Having scripts diddle user written config files seems potentially
dangerous. Plus there's really no downside to including some
empty files. Best to just make the includes be permanent.
Additional feature suggested by Luiz: if a -opkg version of the
config file was created unnecessarily, remove it as part of the
upgrade process since changes won't be happening to that file
as an artifact of the service starting. The include lines are
now permanent, which means that (1) additional configuration
synthesized by UCI won't be anywhere that opkg (or sysupgrade,
for that matter) cares about since it won't be persistent, and
(2) if changes are being made, then they're being done by a
person with an editor and they really should be distinguished.

This has been observed by myself and @luizluca: ip route get is
appending uid0 to the output, as seen from:
root@OpenWrt2:~# ip route get 1.1.1.1
1.1.1.1 via 174.27.160.1 dev eth3 src 174.27.182.184 uid 0
cache
root@OpenWrt2:~#
so the fix is an anchored match, discarding all else. Also, using
ip -o means never having to do multiline matches...

This commit allows for UCI configuration of the "left=" and the
"mark=" values in a StrongSwan IPSec connection. This improves
VTI support and allows certain stricter connection scenarios.

When building with strongswan-ipsec disabled, strongswan fails to build
because the ipsec.conf file does not exist. Fix this by moving the
ipsec.* files and directories to the strongswan-ipsec package.
Closes#10879 while keeping ipsec.conf to avoid breaking existing
setups, as opposed to #11709.

Add a conffiles-section for the /etc/swanctl folder, which is used by the swanctl util. This will keep the configfiles during an sysupgrade.

This is useful to assign all traffic to a fw3 zone, e.g.:
/etc/config/ipsec:
config remote 'test'
list tunnel 'dev'
...
config 'tunnel' 'dev'
option reqid '33'
...
/etc/config/firewall:
config zone
option name wan
option extra_src "-m policy --pol none --dir in"
option extra_dest "-m policy --pol none --dir out"
...
config zone
option name vpn
# subnet needed for firewall3 before 22 Nov 2019, 8174814a
list subnet '0.0.0.0/0'
option extra_src "-m policy --pol ipsec --dir in --reqid 33"
option extra_dest "-m policy --pol ipsec --dir out --reqid 33"

The CONTRIBUTING.md requests an (or multiple) SPDX identifier for GPL

Commit 6cd8fcabe added ipsec hotplug script support by calling "exec
/sbin/hotplug-call ipsec".
Using the exec call breaks the insertion of iptables rules by the _updown.in
script as hotplug-call just replaces the current shell meaning the commands
following exec do not run since the shell is replaced and as a result lead to
connectivity issues.
Fix this by removing the exec command in front of /sbin/hotplug-call.

Ipsec user script (/etc/ipsec.user) now get called indirectly by openwrt
"/sbin/hotplug-call". So other packages could also install their scripts

The interface config option allows users to configure logical OpenWRT
interface names in the ipsec section; it allows StrongSwan to listen
and send traffic on specified interface(s). It translates to interfaces_use
StrongSwan option which is a comma sepearted list of network devices
that should be used by charon.
Since StrongSwan can only be started when one of the specified logical
OpenWRT interface is up procd interface triggers are installed to
trigger the reload script.

Based on the ipsec running state reload_service is either reloading ipsec
or starting ipsec. However in the latter case it calls ipsec start which
bypasses the procd start_service function which means the running ipsec
instance is not managed by procd.
Fix this by calling start in case ipsec is not running; at the same time
add service_running function which is used by procd provided running
function.

When the strongswan service is running, `ipsec status` returns 0. Check
the return value instead of checking its output.
While at it, remove the [[ ]] bashism, use rereadall instead of
(reread)secrets, and move it inside the if statement.

In commit 36e073d820, some checks were
added to see if the UCI config file exists and if there are any peers
configured in it. Due to these checks, if /etc/config/ipsec exists, but
contains no enabled peers, strongswan will not be started. This is not
ideal, as a user might want to experiment with the UCI config while
keeping existing connections in /etc/ipsec.conf operational.

We currently include the SCEP client in strongswan-utils, which is a
dependency of the strongswan-default meta-package. As it's generally not
recommended to generate keys on embedded devices due to lack of entropy,
move the SCEP client to a separate package, and only depend on it in the
strongswan-full meta-package.
While at it, add scepclient.conf to the package.
