The change in name signals that data-ciphers is the preferred way to
configure data channel (and not --cipher). The data prefix is chosen
to avoid ambiguity and make it distinct from tls-cipher for the TLS
ciphers.

This allows us to skip waiting for the first PUSH_REQUEST message from
the client to send the response.
This changes the interpretation of IV_PROTO from a scalar to a bitfield
Since we only have IV_PROTO=2 defined so far and will support DATA_V2
this should not make any problem. This avoid adding another IV_xxx variable
that takes valuable space in the protocol frame.

By default OpenSSL 1.1+ only allows signatures and ecdh/ecdhx from the
default list of X25519:secp256r1:X448:secp521r1:secp384r1. In
TLS1.3 key exchange is independent from the signature/key of the
certificates, so allowing all groups per default is not a sensible
choice anymore and instead a shorter list is reasonable.
However, when using certificates with exotic curves that are not on
the group list, the signatures of these certificates will no longer
be accepted.
The tls-groups option allows to modify the group list to account
for these corner cases.
Patch V2: Uses local gc_arena instead of malloc/free, reword commit
message. Fix other typos/clarify messages
Patch V3: Style fixes, adjust code to changes from mbedTLS session
fix
Patch V5: Fix compilation with OpenSSL 1.0.2
Patch V6: Redo the 'while((token = strsep(&tmp_groups, ":"))' change
which accidentally got lost.

Due to the VORACLE attack vector, compression in general is deprecated.
Make this clear in the man page.
Also remove an incorrect statement claiming --compress lzo is compatible
with --comp-lzo. It is not, as --compress lzo uses a different
compression framing than --comp-lzo.

doc/man: Add an .rst formatted version of the man page
This is the first step to move away from a manually editing g/nroff
encoded man page.
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
project: https://docutils.sourceforge.io/

doc/man: Replace old man page with generated man page
The doc/openvpn.8 and doc/openvpn.8.html files are now being removed
from the git tree, as it will be generated from the doc/openvpn.8.rst
file using python-docutils.
An additional dist-hook is added so these files are generated
automatically when source tarballs are generated for releases. This
means users compiling directly from the source tarball will not need
python-docutils installed.

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.
