[PATCH v1 0/2] Add logind and sysfs power methods

[Alberto Milone]

pm-utils is now deprecated and, as a result, we should rely on
either Logind (where available) or on sysfs.

This is a first draft I've been working on. The new code features
autodetection (which defaults to Logind, and falls back to sysfs)
in addition to adding the --pm-method parameter to allow users
to specify one of the following methods:

logind, sysfs, pm-utils

Quirks are only available when using pm-utils but this shouldn't
be a blocker for the adoption of these additional methods.

I used the GLib Dbus bindings only to avoid using the C Dbus
bindings. While this adds a dependency on GLib, it's a small
price to pay.

Similar code should be written to handle S4, which I plan to do
as soon as we agree on the final details of the current patches
for S3. It would probably be a good idea for s3.c and s4.c to
share the same code.

The new functions in fwts_pipeio.c and fwts_stringextras.c come
from Logind's source code (whose LGPL 2.1 is compatible with
FWTS'). I have given credit to the original author but please
let me know if there's a better way to do it.

This also fixes LP: #1339588
