* Merge from Debian unstable (LP: #1076536), remaining changes: - Replace init script with Upstart job + This does not load modules, unlike the init script, since these are all loaded by ACPI:* modaliases now (and thus by udev) - debian/control: Bump build-dependency on debhelper for Upstart-aware dh_installinit - debian/acpid.install, debian/acpid.preinst, debian/rules: continue installing /etc/acpi/events/powerbtn and /etc/acpi/powerbtn.sh, deferring the migration to acpi-support-base; and drop the Recommends: on acpi-support-base for the same reason. - Source /usr/share/acpi-support/power-funcs in powerbtn.sh - debian/powerbtn.sh: ensure that /usr/share/acpi-support/power-funcs exists before sourcing it; note that acpid does not depend on acpi-support (which is fine, as it brings in lots of X dependencies not appropriate for servers); this fix will allow Ubuntu servers (especially those in VMs) to run acpid and catch and handle power button events again. - debian/powerbtn.sh: gnome-power-manager is no more, check for gnome-settings-daemon now. This fixes immediate shutdown when the power button is pressed. - debian/acpid.install, debian/acpid.links: Don't install socket and service files needed by systemd
