Ivan Shapovalov 42483a7474 hibernate-resume: add a tool to write a device node's major:minor to /sys/power/resume.
This can be used to initiate a resume from hibernation by path to a swap
device containing the hibernation image.

The respective templated unit is also added. It is instantiated using
path to the desired resume device.

<title>Description</title>
<para><filename>systemd-hibernate-resume@.service</filename> is a
service that initiates hibernation resume from a device
containing the resume image. It is instantiated for each
device that is configured for resuming from.</para>
<para><filename>systemd-hibernate-resume</filename> only supports
the in-kernel hibernation implementation, known as swsusp.
Internally, it works by writing the major:minor of specified
device node to <filename>/sys/power/resume</filename>.</para>
<para>Failing to initiate a resume is not an error condition.
It may mean that there was no resume image (e. g. if the
system has been simply powered off and not hibernated). In
such case, the boot is ordinarily continued.</para>
