If we don't split peer linking off, the peer might get advertised before
the sub-device related data is set. With dbus, this might trigger
callbacks to not return attributes as the peer-type is unknown. Therefore,
properly initialize the peer before linking/advertising it.
This fixes a bug where the initial InterfacesAdded signal for new peers
does not include all properties of a peer.

Both dbus commands allow external programs to make our device discoverable
for P2P devices and also start scanning for remote devices.
The commands are *not* ref-counted right now, so parallel use is
discouraged. However, these commands can interrupt normal operations on a
wifi-device anyway, so if used in parallel, it is very like to break.
Thus, keep the interface simple and require callers to do
access-management (it's root-only, anyway..).

Send ObjectManager.Interfaces{Added,Removed} signals whenever new objects
appear. Note that we cannot set DBus interfaces there as sd-bus ignores
them. We'll try to fix that upstream and until then just not expose any of
those.

We need to send PropertiesChanged signals whenever we change properties
that are annotated as such.

This command prints detailed information on a given peer. This is exactly
the same as 'show-link' but for peers.

Implement basic peer properties and hook them up with dbus. Also add a
device_name parser to the wifi implementation so we correctly read the
friendly-name of remote devices.

Move peer_make_name() to the top to keep consistency with miracled-link.c
and move non-object-based helpers to the top.

The new show-link command lists detailed information of a given link.
Useful for debugging and introspection.

The friendly-name is used as name for local links. Default to a random
string and try to read the local hostname during startup.

This initial commit contains the main "miracled" daemon that does
link-management and peer-discovery/control. The "miraclectl" tool can be
used to control this daemon during runtime.
Note that this implementation is still missing a lot of stuff. All it
currently does is provide link-management and basic peer-discovery.
Following commits will hook everything else up.
The actual Miracast/Wifi-Display related runtime control is not being
worked on, yet. Feel free to use the proof-of-concept from the OpenWFD
repository. The MiracleCast implementation will not get any such
functionality unless the basic link-management is properly working.
