Since iwd_modules_init is now defered until nl80211_appeared, we can
assume the nl80211 object is available. This removes the need for
netdev_set_nl80211 completely.
In preparation for integrating IWD_MODULE into modules which require
nl80211 we move the module init into the nl80211_appeared callback.
This will guarentee that the nl80211 is available during module init
and allow modules to get their own copy of nl80211 rather than needing
a set function (e.g. netdev_set_nl80211).
Since the dbus name request callback happens before this as well any
dbus module can also use IWD_MODULE and simply assume the dbus object
is ready.
plugin_init was also deferred to nl80211_appeared since some plugins
depend on modules being initialized.
Mirror netdev.c white/blacklist logic. If either or both the whitelist
and the blacklist are given also fall back to not touching the existing
interface setup on the wiphy.
Add manager.c, a new file where the wiphy and interface creation/removal
will be handled and interface use policies will be implemented. Since
not all kernel-side nl80211 interfaces are tied to kernel-side netdevs,
netdev.c can't manage all of the interfaces that we will be using, so
the logic is being moved to a common place where all interfaces on a
wiphy will be managed according to the policy, device support for things
like P2P and user enabling/disabling/connecting with P2P which require
interfaces to be dynamically added and removed.
Previously, the storage dir has only been created after a successful
network connection, causing removal of Known Network interface from
Dbus and failure to register dir watcher until daemon is restarted.
This will allow for blacklisting a BSS if the connection fails. The
actual blacklist module is simple and must be driven by station. All
it does is add BSS addresses, a timestamp, and a timeout to a queue.
Entries can also be removed, or checked if they exist. The blacklist
timeout is configuratble in main.conf, as well as the blacklist
timeout multiplier and maximum timeout. The multiplier is used after
a blacklisted BSS timeout expires but we still fail to connect on the
next connection attempt. We multiply the current timeout by the
multiplier so the BSS remains in the blacklist for a larger growing
amount of time until it reaches the maximum (24 hours by default).
Using backtrace() is of no use when building with PIE (which most
distro compilers do by default) and prevents catching the coredump
for later retracing, which is needed since distros usually don't
install debug symbols by default either.
This patch thus only enables backtrace() when --enable-maintainer-mode
is passed and also tries to explicitly disable PIE.
Check for HAVE_EXECINFO_H for all __iwd_backtrace_init usages.
Fixes:

Adhoc requires 2 GTK's to be set, a single TX GTK and a per-mac RX GTK.
The per-mac RX GTK already gets set via netdev_set_gtk. The single TX GTK
is created the same as AP, where, upon the first station connecting a GTK
is generated and set in the kernel. Then any subsequent stations use
GET_KEY to retrieve the GTK and set it in the handshake.
