main.c-Use-the-existing-user-D-Bus-session-bus-instead-of.patch main.c: Use the existing user D-Bus session bus instead of spawning dbus-launch.

require_dbus_session() only looked at DBUS_SESSION_BUS_ADDRESS, so with
the variable unset it re-exec'd the session under `dbus-launch
--exit-with-session` even when the user already had a session bus
running on the well-known socket at $XDG_RUNTIME_DIR/bus (the default on
systemd, and on elogind setups with dbus configured for the user bus).
That starts a second bus, splitting activatable services and portals
across the two, and on systems that ship no dbus-launch binary (Debian
with only dbus-user-session installed) the session does not start at
all.

X11 logins usually escape this because the display manager wraps the
session in a script that exports DBUS_SESSION_BUS_ADDRESS, but the
Wayland session does not go through those wrappers, so it depends on the
display manager.

Ask GDBus for the session bus address first: it looks for the socket at
$XDG_RUNTIME_DIR/bus, and we export the address so every child of the
session ends up on the same bus. The dbus-launch fallback stays for
setups without a user bus, so nothing changes there. This is what
gnome-session does in leader-main.c.

main.c-Report-the-failure-when-dbus-launch-cannot-be-exec.patch main.c: Report the failure when dbus-launch cannot be executed.
execvp() returns only when it failed, and then it always returns -1, so
`if (!execvp (...))` was never true: the g_set_error() branch was dead
code. Instead of failing with "No session bus and could not exec
dbus-launch", require_dbus_session() fell through to the `return TRUE`
marked "Should not be reached" and the session kept going with no
session bus at all, silently, until something else broke further down.

Call execvp() and treat its return as the failure it is.

This is easier to hit than it looks on systems that ship no dbus-launch
binary, and the previous patch does not change that: it only makes the
fallback rarer, not the failure mode better.

csm-systemd.c-Take-the-session-s-logind-inhibitor-in-bloc.patch csm-systemd.c: Take the session's logind inhibitor in block-weak mode when available. (#219)

Since systemd 257, logind always obeys "block" inhibitors, including the
ones held by the user who requests the operation (before, those were
ignored for the same user and for root). The "sleep:shutdown" inhibitor
that cinnamon-session takes on behalf of applications inhibiting suspend
(Rhythmbox while playing, browsers playing media, ...) now blocks the
session itself:

- closing the lid: csd-power locks the screen and calls Suspend(), which
is refused, so the laptop stays on;
- end-session dialog: logind answers "inhibited" to
CanSuspend/CanPowerOff/CanReboot, so suspend, restart and shut down are
not offered, and "Ignore and continue" for suspend does nothing.

The "block-weak" mode, added in systemd 257, keeps the previous
semantics. Suspend on idle still honours the inhibitors, since csd-power
checks the session inhibitors itself before arming the sleep timeout.
gnome-session did the same (39d51c9e6, "systemd: Downgrade suspend
inhibitor to block-weak").

systemd-logind and elogind older than 257 don't know "block-weak": there
the inhibitor is still taken in "block" mode, which on those versions is
ignored for the same user anyway. The BlockWeakInhibited property, added
together with the new mode, tells the two apart.
