- Update to 2.4.6:
* CVE-2018-9336, bsc#1090839: Fix potential double-free() in
Interactive Service
* Delete the IPv6 route to the "connected" network on tun close
* Management: warn about password only when the option is in use
* Avoid overflow in wakeup time computation

- Remove --askpass again, because it was also asking for a password
when none was needed. As a workaround for keys that need a
password, the "askpass" statement should be added to the config
file (bsc#1078026).
- Use Type=notify in openvpn.service to reflect what openvpn is
actually doing.
- Import the new signing key from upstream.
- Remove obsolete configure switch --enable-password-save .

- Update to 2.4.5
* New features
+ The new option --tls-cert-profile can be used to restrict the
set of allowed crypto algorithms in TLS certificates in mbed
TLS builds. The default profile is 'legacy' for now, which
allows SHA1+, RSA-1024+ and any elliptic curve certificates.
The default will be changed to the 'preferred' profile in the
future, which requires SHA2+, RSA-2048+ and any curve.
+ openvpnserv: Add support for multi-instances (to support
multiple parallel OpenVPN installations, like EduVPN and
regular OpenVPN)
+ Use P_DATA_V2 for server->client packets too (better packet
alignment)
+ improve management interface documentation
