Since commit bd9aa06feb (Jan 2015) OpenVPN has allowed to use
'--dh none' to disable traditional Diffie Hellman, since more secure
ECDH algorithms are available that do not use explicit DH parameters.
If configured with a suffiently high securelevel (3+), or if running in
FIPS mode, OpenSSL 3.5 will refuse 2048 bit DH files, making our tests
fail.
Thus, remove all the DH2048 stuff from our sample configs.

- Remove compression settings. Not recommended anymore.
- Remove old cipher setting. Replaced by data-ciphers negotiation.
- Add comment how to set data-ciphers for very old clients.
- Remove/reword some old comments. e.g. no need to reference
OpenVPN 1.x anymore.
- Mention peer-fingerprint alternative.
- comment out "tls-auth" as that is not needed for a bare-bones VPN config
and needs additional setup.

Change the default behavior of the OpenVPN configuration
by enabling the persist-key option by default.
This means that all the keys will be kept in memory
across restart.

Recommend to create an user dedicated to openvpn
so that there is no priviledge escalation between
different services using that user.

This unifies our key generation and also migrates the generation
of the tls-crypt-v2 keys. Since tls-crypt-v2 is not included in any
released version, we remove the the old syntax without compatibility.
PATCH V4: Introduce warning/error when using --secret with --genkey
Update non code usages to use new --genkey syntax

A simple clean-up where the version references have been unified
all those places I could find now. The versioning scheme used is:
* OpenVPN 2.x
* v2.x
We want to avoid:
* 2.x (2.4 can be just an ordindary decimal number,
OID reference, a version number or anything else)
* OpenVPN v2.x (OpenVPN indicates we're talking about a version)
In addition, several places where it made sense I tried to ensure
the first version reference uses "OpenVPN 2.x" and the following
references in the same section/paragraph uses "v2.x", to set the
context for the version reference.
In Changes.rst modified paragraphs exceeding 80 chars lines where
reformatted as well.

For two reasons:
1) May motivate people to use tls-auth in their setups
2) Verify tls-auth functionality when running 'make check'

I kept most of the certificate properties equal to the old
certs, since some people's test scripts might rely on them (and
it does not require any creativity from my part).
Changes:
* Add script to generate fresh test/sample keys
(but keep sample keys in git for simple testing)
* Switch from 1024 to 4096 bits RSA CA
* Switch from 1024 to 2048 bits client/server RSA keys
* Switch from 1024 to 2048 bits Diffie-Hellman parameters
* Generate EC client and server cert, but sign with RSA CA
(lets us test EC <-> RSA interoperability)
* Remove 3DES cipher from 'sample' config
* Add 'remote-cert-tls server' to client config
* Update config files to deprecate nsCertType in favour of the
keyUsage and extendedKeyUsage extensions.
* Make naming more consistent

This is an OpenPGP/MIME signed message (RFC 4880 and 3156)
On modern systems, topology subnet should always be set, but it's
missing in the configuration file.
