Update to 20210401. From the changelog:

- fix IPv6 split masklen
- vpnc-script-win: tidy up, more logging
- vpnc-script-win: make VPN addresses/gateways "non-persistent", and
  delete them on disconnect
- vpnc-script-win: delete DNS and WINS servers before adding them
- vpnc-script-win: dump stdout and stderr when a command fails
- vpnc-script-win: use TUNIDX in all netsh commands, remove
  waitForInterface()
- vpnc-script-win: add FIXMEs regard IPv6 split-excludes and gateways

- mention IDLE_TIMEOUT
- cleanup whitespace and clarify comments
- tweak warning message about un-routable exclude routes
- Ignore unreachable exclude routes
- Document split tunnel EXC variables
- ignore bogus non-forwardable exclude routes on disconnect too
- *BSDs: get_default_gw needs to EXCLUDE routes through tunnel for

- mark tunnel device 'down' before destroying
- Add DragonFly BSD support and improve FreeBSD support
- Use '[[:space:]]' instead of '\s' to support POSIX awk

  default route
- Fix basename invocation on *BSD shells
- fix another ifconfig syntax difference between Linux and *BSDs
- use `ip netns` instead of ocserv `listen-netns` config option for
  test configs

- FIXME add mock IPv6 configuration to get CI to work
- add a bit more logging to test scripts
- split iproute2 and *BSD-ish into separate CI runs
- CI: don't need to install ocserv and which
- numerous fixes for Linux IPv6 configuration using
  ifconfig/route/netstat
- try running tests with *BSD-ish tools (ifconfig/route/netstat) for
  additional coverage
- match code style
- Don't use /sbin/resolvconf if it just points to resolvectl.
- include calling process ID in DEFAULT_ROUTE_FILE{,_IPV6}
- with BSD 'route', save-and-restore IPv6 default routes
- simplify cases and add ifconfig_syntax_del variable

- vpnc-scripts: added a sanity check of routes and resolv.conf
  generation

- iproute2 5.1+ doesn't allow prefixlen!=32 in get

Log message:
Update to 20190606. From the changelog:

Previously, an IPv6 split tunnel with a /128 request would result in a
default tunnel, rather than a specific route. Correctly set the default
route if we request a /0.

If `which ip` returns something on a non-Linux OS, it's an unrelated
tool that won't work for routing configuration; don't try to set IPROUTE
on another OS. This should fix the macOS issue discovered at:
<https://github.com/dlenski/openconnect/issues/132#issuecomment-470475009>

Log message:
Update to 20190424. From the changelog:

Some vpn clients pass multiple domains for DNS search scope, which
requires that we use search rather than domain. The generic path was
already using search, so just switch the resolvconf path to also use
search.

In a container, /etc/nsswitch.conf might not exist.
Silence the error grep: /etc/nsswitch.conf: No such file or directory

Inside a container, running 'ip route flush cache' can spam with
"ip: can't open '/proc/sys/net/ipv4/route/flush': Read-only file system"
Hide that the error output for that command.
