systemd-sleep: add support for freeze and standby
A new config file /etc/systemd/sleep.conf is added. It is parsed by systemd-sleep and logind. The strings written to /sys/power/disk and /sys/power/state can be configured. This allows people to use different modes of suspend on systems with broken or special hardware. Configuration is shared between systemd-sleep and logind to enable logind to answer the question "can the system be put to sleep" as correctly as possible without actually invoking the action. If the user configured systemd-sleep to only use 'freeze', but current kernel does not support it, logind will properly report that the system cannot be put to sleep. https://bugs.freedesktop.org/show_bug.cgi?id=57793 https://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=7e73c5ae6e7991a6c01f6d096ff8afaef4458c36 http://lists.freedesktop.org/archives/systemd-devel/2013-February/009238.html SYSTEM_CONFIG_FILE and USER_CONFIG_FILE defines were removed since they were used in only a few places and with the addition of /etc/systemd/sleep.conf it becomes easier to just append the name of each file to the dir name.
