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
in "/etc/hotplug.d/ipsec".

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.

Since the strongswan-utils package now only contains the aging ipsec
utility, rename it to strongswan-ipsec.

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.

Add support to configure strongswan via uci.
uci support is based on the following sections
-ipsec : Global config items belonging in the strongswan.conf file
-remote : Defines the remote peer(s)
-tunnel : Defines the IPSec connections in tunnel mode
-transport : Defines the IPSec connections in transport mode
-crypto_proposal : Defines the different crypto proposals

Patch 101-musl-fixes defines __kernel_nlink_t as void; but using

musl.h was included before _GNU_SOURCE in 101-musl-fixes patch
leading to compilation issue on gcc (RTLD_DEFAULT not being
defined in dlfcn.h due to __USE_GNU not being set).
As described in the feature test macro man page feature macro
can be defined in the source code but need to be defined before
including any headers.

The default busybox config used by OpenWrt does not enable floating
point number support for the sleep applet. This can cause an error when
stopping or restarting strongswan:
sleep: invalid number '0.1'
Replace the float with an integer to fix this.

gmpdh plugin implements DH Groups (same as normal GMP plugin), but links to GMP statically and is stripped of all RSA based stuff. Binary size for plugin is ~20kbytes with no dependency on libgmp (200+ kbytes after squash), easilly fitting into flash space restricted devices.
strongswan-isakmp metapackage defines a minimal set of strongswan plugins (including gmpdh) for ISAKMP / IKEv1 PSK tunnels. Will fit even 4mb routers (like tplink wr841n) with disabled IPv6 support and packages (so its a trade - IPv6 or ipsec tunnels).

Makes kmod-ipsec6 requirement dependent on IPv6 support for packages.
This allows to disable unnecessary IPv6 kernel modules, saving
considerable amount of space.
