The function cipher_kt_key_size expects its argument to be not

At the moment if --name is not specified, adapter names
are generated by Windows and they look a bit confusing
like "Local Area Connection 2".
This is also behavior of "Add a new <driver-name> virtual network
adapter" shortcuts.
This makes tapctl generate driver-specific names for adapters
if --name is missing, inclusing resolving duplicates. For instance
following commands:
tapctl.exe create --hwid ovpn-dco
will create an adapter named
OpenVPN Data Channel Offload
If the name is taken, the next one will be
OpenVPN Data Channel Offload #1
and so on up to 100.

Setting the desktop as "winsta0\default" does not always work when run
from a non-interactive session which may not have access to the
the window station "Winsta0". Leave this as NULL to let the system
automatically assign a window station and desktop.
Test runs on Win10 confirm that "Winsta0\Default" still gets selected
when run interactively (e.g., using the GUI or from task scheduler as
an interactive job). This is the same behaviour as now.
The change allows "interactive service" to be used for launching
OpenVPN from non-interactive sessions. For example, when service client
is a non-interactive task from the task scheduler, the default desktop
in a custom window station gets assigned to openvpn.exe.
Note that we already run openvpn.exe in a non-interactive window
station when directly launched by "automatic service".

Since we use strlen() to determine the length
and then check it ourselves, there is really
no point in using strncpy.
But the compiler might complain that we use
the output of strlen() for the length of
strncpy which is usually a sign for bugs:
error: ‘strncpy’ specified bound depends
on the length of the source argument
[-Werror=stringop-overflow=]
Warning was at least triggered for

- remove useless casts

Currently we use the ANSI version of CreateEvent causing name of the
exit event to be interpreted differently depending on the code page
in effect. Internally all strings parsed from command line and config
file are stored as UTF8-encoded Uniode. When passed to Windows API calls,
these should be converted to UTF16 and wide character version of the API
should be used.
CreateEvent calls for unnamed events are left unchanged as there is no
text-encoding dependence in those cases.

This implements setting DNS domain via WMIC command,

Limitations:
Depends on libsofthsm2.so and p11tool (install softhsm2 and gnutls-bin
packages). Mbed-TLS/pkcs11-helper combination is not tested.
If locations of these binaries are not auto-detected or need to be
overridden, use -DSOFTHSM2_UTIL=<path> -DP11TOOL=<path> to configure.
Location of SOFTHSM2_MODULE is not auto-detected and defaults to
/usr/lib/softhsm/libsofthsm2.so. It may be changed by passing
-DSOFTHSM2_MODULE=/some-path/libsofthsm2.so to configure.
Also see "configure --help".
The test is enabled only if --enable-pkcs11 is in use, and SOFTHSM2_UTIL
& P11TOOL are found in path or manually defined during configuring.
Changes relative to github PR
- Explicitly disable building the test on Windows: need to port mkstemp,
mkdtemp, setenv etc., before enabling this on Windows.

We persist peer-stats when restarting, but an early restart
before open_tun results in a segfault in dco_get_peer_stats().
To reproduce, trigger a TLS handshake error due to lack of common
protocols, for example.
Fix by checking that tuntap is defined before dereferencing it.

Socket flags can be pushed, in which case they overwrite
existing value. We use socket flags to distingust between
DCO handle and socket on Windows. If server pushes --socket-flags,
we treat DCO handle as socket and everything explodes.
Fix by making link_socket_update_flags() update flags
(like name suggests) instead of overwriting them. Also
do not set TCP_NODELAY on DCO handle on Windows because
it doesn't make sense.

This change keeps the option parsing of compression options even when
compression is disabled. This allows OpenVPN to also refuse/reject
connections that try to use compression when compression is completely
disabled.

This changes the "no" setting of allow-compression to also refuse framing
if DCO is active. This is important for our DCO implementations as these
do not implement framing.
This behaviour surfaced when a commercial VPN provider was pushing
"comp-lzo no" to a client with DCO. While we are technically at fault here
for announcing comp-lzo no support by announcing IV_LZO_STUB=1, the
VPN provider continues to push "comp-lzo no" even in absense of that
flag.
As the new default we default to 'allow-compression no' if DCO is
enabled and to 'allow-compression stub' otherwise.
This will now also bail out if the server pushes a compression setting that
we do not support as mismatching compression is almost never a working
connection. In the case of lz4-v2 and lzo-v2 you might have a connection
that works mostly but some packets will be dropped since they compressed
which is not desirable either since it becomes very hard to debug.
Patch v2: bail out if server pushes an unsupported method. Also include this
bail out logic when OpenVPN is compiled without compression support.
Patch v3: always parse all compression option and move logic to check method
Patch v4: fix for not setting correct default for non-dco

This removes also the checks in options.c itself as they we now bail out
later and no longer need to ignore them during parsing.

With this API it is possible to retrieve the stats for a specific peer
or for all peers and then update the userspace counters with the value
reported by DCO.
