This is a bugfix release containing several security fixes.
Security fixes
--------------
- CVE-2024-4877: Windows: harden interactive service pipe.
Security scope: a malicious process with "some" elevated privileges
could open the pipe a second time, tricking openvn GUI
into providing user credentials (tokens), getting full access
to the account openvpn-gui.exe runs as.
- CVE-2024-5594: control channel: refuse control channel messages
with nonprintable characters in them.
Security scope: a malicious openvpn peer can send garbage to openvpn log,
or cause high CPU load.
- CVE-2024-28882: only call schedule_exit() once (on a given peer).
Security scope: an authenticated client can make the server "keep the session"
even when the server has been told to disconnect this client
Bug fixes

This commit updates openvpn to version 2.6.5 and add DCO support.
There are several changes:
- Starting with version 2.6.0, the sources are only provided as .tar.gz
file.
- removed OPENVPN_<variant>_ENABLE_MULTIHOME:
multihome support is always included and cannot be disabled anymore
with 2.6.x.
- removed OPENVPN_<variant>_ENABLE_DEF_AUTH:
deferred auth support is always included and cannot be disabled
anymore with 2.6.x.
- removed OPENVPN_<variant>_ENABLE_PF:
PF (packet filtering) support was removed in 2.6.x.
- The internal lz4 library was removed in 2.6.x; we now use the liblz4
package if needed
- To increase reproducibility, _DATE_ is only used for development
builds and not in release builds in 2.6.x.
- wolfSSL support was integrated into upstream openvpn
- DES support was removed from openvpn
The first two wolfSSL patches were created following these 2 commits:

Support for wolfSSL has been upstreamed to the master OpenVPN branch
in f6dca235ae560597a0763f0c98fcc9130b80ccf4 so we can use wolfSSL
directly in OpenVPN. So no more needed differnt SSL engine for OpenVPN
in systems based on wolfSSL library
Compiled && tested on ramips/mt7620, ramips/mt7621
