and only allow the aead tag at the end if epoch data keys are
used, we can use just one flag for both of them

This is highly system specific, as the content of the uname()
structure elements is not specified very well - uname(3) says:
release Release level of the operating system
which translates to "IV_PLAT_VER=13.3-RELEASE-p6" (FreeBSD) or
"IV_PLAT_VER=22.6.0" (macOS) - the latter being the "Mach Kernel
version", not what Apple calls the OS.
It's still useful if a server operator needs to keep track of
client versions (and the GUI does not set the corresponding
environment variable, which neither Tunnelblick nor NM do).

Extend "--static-challenge" option to take a third
argument (= scrv1 or concat) to specify that the password and
response should be concatenated instead of using the
SCRV1 protocol. If unspecified, it defaults to "scrv1"
meaning that the SCRV1 protocol should be used.
v2: use scrv1|concat instead of 0|1 as option argument

No DNS resolver currently supports this and it is not possible to
emulate the behavior without the chance of errors. Finding the
effective default system DNS server(s) to specify the exclude
DNS routes is not trivial and cannot be verified to be correct
without resolver internal knowledge. So, it is better to not
support this instead of supporting it, but incorrectly.

This change allows configuration of more than one address per family
for a DNS server. This way you can specify backup addresses in case a
server is not reachable. During closer inspection of the various DNS
backend in supported operation systems it turned out that our previous
idea to have more than one DNS server applied in order of priority does
not work in most cases. Thus it became important to be able to specify
backup addresses. So instead of doing
dns server 1 address 1.2.3.4 2001::1
dns server 2 address 5.6.7.8 2001::2
to specify a backup addresses, this is now done like so:
dns server 1 address 1.2.3.4 2001::1
dns server 1 address 5.6.7.8 2001::2
or you can have all the addresses on one line if you like:
dns server 1 address 1.2.3.4 2001::1 2001::2 5.6.7.8
This also saves some repeated options when (backup) servers share the
same settings like "resolve-domains" compared to the originally intended
way.
The order in which addresses are given is retained for backends that
support this sort of cross address family ordering.

Current exit notification relies on data channel messages with specific
prefix. Adding these to new data channel modules (DCO) adds unncessary
complexity for the data for messages that from their idea belong to the
control channel anyway.
This patch adds announcing support for control channel and sending/receving
it. We use the simple EXIT message for this.
Patch v2: add comment about protocol-flags to be not a user visible option,
fix various grammar mistakes, remove unused argument to
receive_exit_message
Patch v3: rename data_channel_crypto_flags to imported_protocol_flags
add tls-ekm to protocol-flags.

As a first step towards DNS configuration in openvpn and a unified way
to push DNS related settings to clients in v2 and v3, this commit adds
support for parsing the new --dns option. Later commits will add support
for setting up DNS on different platforms.
For now, --dns and DNS related --dhcp-option can be used together for
smoother transition. Settings from --dns will override ones --dhcp-option
where applicable.
For detailed information about the option consult the documentation in
this commit.

When not using username and password (i.e. auth-user-pass) it can still
be desirable to provide the client with an auth-token, e.g. for allowing
a session to continue after a reconnect without requiring 2FA again.
However, without --auth-user-pass openvpn does not have a username and will
ignore any pushed auth-token command.
This patch adds support for auth-token-user to set the username that should
be used for auth-token
The spec of using auth-token-user base64-encoded-user are the ones that
OpenVPN3 already implements.

This is the first step to move away from a manually editing g/nroff

Some modifications was needed to ensure formatting was consistent and
rendered reasonably okay in GitHub and that the generated man page
(using rst2man) is looking as a proper man page. Unsupported options
has also been moved into its own section. HTML rendering directly
using rst2html has also been used to validate the conversion.
The rst2man and rst2html utilities comes from the python-docutils

doc/man: Split up and reorganize main man page
The openvpn.8.rst file is quite long and hard to edit, as it covers
several hundred options. Some options were even documented multiple
places. The example has also received some attention, cleaning up
old and outdated infomration.
In this commit the main man page is split up into multiple sections
and options are sorted into each of the corresponding section.
Inside each category, each option is for now sorted alphabetically.
The main openvpn.8.rst file is currently kept unchanged and will be
handled in the next commit.
Many language improvements contributed by Richard Bonhomme has also
been incorproated.
