Properly notify API users if we free peers that are pending. This way,
they don't have to use timers to restart peer discovery on wpa_supplicant
failures.

If there is already a connection pending, don't start a new one.
Unfortunately, wpa_supplicant is unable to deal with this so we have to
enforce this.. Yuck!
We also reset the pending state during P2P_FIND now, this enables API
users to reset failed connections that wpa_supplicant was unable to close
(yeah, beacuse it's so hard to write proper APIs.. *sigh*).

No need to add 'display' to p2p_connect commands. Drop it for future

P2P-PEER reports the device name as 'device_name' while P2P-DEVICE-FOUND
reports it as 'name'. Try both.

Forward group-formation-failure events via dbus so sinkctl can restart
p2p-scans immediately. Unfortunately, the event itself does not contain
any useful information at all. Therefore, we have to track the connection
attempts ourselves.

sd_bus never uses 'bool', and given the weird implicit type promotions, it
is totally right to do so. Make sure we never pass pointers to 'bool' to
va_arg sd_bus functions to avoid overwriting stack space.

If we delay device-parsing until P2P_PEER returns, we might receive other
device events in between which we cannot handle as the peer is unknown.
Avoid that by immediately creating the peer and appending more detailed
data later once P2P_PEER returns.
As P2P_PEER keys and P2P_DEVICE_FOUND keys are different (wholy shit, what
a fucking interface), we need to parse both. Lets hope there won't be any
conflicts.
WARNING: The wfd_subelements field is currently very inconsistent.
Sometimes we only use dev_info fields, somethings the whole IE. Users
shall use it as boolean value, only (set vs. unset). Once we add a proper
IE parser, we will provide more advanced fields.

wpa_supplicant is horrible in notifying us about p2p-scans. During failed
connection attempts or other timeouts, we usually are not notified about
scan-stops. Therefore, a following p2p-scan will simply be ignored as we
think it's still running.
Avoid that problem by always forwarding the P2P_FIND command.
wpa_supplicant can deal with redundant requests so we're fine. Note that
this requires the caller to issue these calls in intervals or/and after
any issues wifi request. Once wpas fixes this issue, we can add this guard
again and the redundant requests will be suppressed.

The miracle-wifid daemon is a rewrite of the wifi-related parts of
miracled. Unlike miracled, we no longer integrate the wifi-part directly
into the core daemon. This way, we can easily replace the wifi-bridge with
other network managers once they gain P2P capabilities.
