335498ca57 docs: direct to systemd.io version of naming scheme docs
The document was imported back in
f9e6d49904. Let's make sure we actually
point to that version rather than the old one on freedesktop.

96848152fa udev: introduce NAMING_STABLE_VIRTUAL_MACS (retroactively)
This is for 6d36464065. It turns out that this is causing more problems than
expected. Let's retroactively introduce naming scheme v241 to conditionalize
this change.

Follow-up for #12792 and 6d36464065. See also
https://bugzilla.suse.com/show_bug.cgi?id=1136600.

2ebe027b44 man: clean up naming scheme description a bit
This is in preparation for later changes.  Let's change the documentation of
net.naming-scheme= to also say that it applies to MAC addresses. This commit
doesn't actually implement that though.

8c053c83ae udev: drop "en" prefix from ID_NET_NAME_ONBOARD
The comment in udev-builtin-net_id.c (removed in grandparent commit) showed the
property without the prefix. I assume that was always the intent, because it
doesn't make much sense to concatenate anything to an arbitrary user-specified
field.

0b1e5b6ed8 man: describe naming schemes in a new man page
I decided to make this a separate man page because it is freakin' long.
This content could equally well go in systemd-udevd.service(8), systemd.link(5),
or a new man page for the net_id builtin.

v2:
- rename to systemd.net-naming-scheme
- add udevadm test-builtin net_id example
