The only difference is that functions are not individually listed by name,
but that seems completely pointless, since all functions that are documented
are always exported, so the generic text tells the user all she or he needs
to know.
Files which are installed as-is (any .service and other unit files, .conf
files, .policy files, etc), are left as is. My assumption is that SPDX
identifiers are not yet that well known, so it's better to retain the
extended header to avoid any doubt.
I also kept any copyright lines. We can probably remove them, but it'd nice to
obtain explicit acks from all involved authors before doing that.
Explanation:
"Please note the login session may be limited to a stub
process or two. User processes may instead be started from their
systemd user manager, e.g. GUI applications started using DBus
activation, as well as service processes which are shared between
multiple logins of the same user."
The most glaring example being when you run commands from gnome-terminal,
or as you see nowadays, "gnome-terminal-server".
*_get_session() is still currently used (directly or indirectly) by Xorg,
Weston etc. running within the session scope. That setup is perfectly
functional, although code will be more generally useful if it is able to
run outside the session scope.[1]

Re-order the man pages a bit at the same time. This is to avoid having the
first and titular entry introduce the session concept, and then immediately
try and persuade you not to use it :).
