The newly set interface may already be in a READY state. In that case,
the device should progress into the DISCONNECTED state rather than
remaining in the UNAVAILABLE state.
Put the device into UNAVAILABLE state when the corresponding WPA
supplicant management interface is unset. This is important to
explicitly clear any pending state changes that are not permissible when
there is no management interface.

Usually, for external/assume we skip calling act_stage2_config().
Add a flag that allows the device to indicate that it always wants
to be called. This is useful, if the device wants to do some initialization
also for external/assume cases.
Instead of performing a series of steps inside one check for
"!nm_device_sys_iface_state_is_external_or_assume (self)", perform
all steps individually (under the same check).
There is no change in behavior, but this is more logical to me.
We perform a series of steps, depending on condition. Each step
individually depends on a set of conditions, instead of checking
for a set of conditions and doing a series of independent steps.
WireGuard devices are (will be) regular NMDevice implementations,
but NMDnsManager should treat them like VPN.
For that, reuse the device's type and nm_device_get_route_metric_default().
Previously, we might have a pending action 'waiting-for-supplicant'
registered, although the device was not waiting:

The previous commit already fixed this bug by dropping the constructor
property for NM_DEVICE_WIFI_P2P_MGMT_IFACE.
Still, refactor handling of pending actions to keep track of whether we
have a pending action registered.
We already have a setter function nm_device_wifi_p2p_set_mgmt_iface()
as we may need to change the mgmt-iface later on. Use that to set the
supplicant interface instead of a constructor property.
That makes the object creation simpler, because nothing noteworthy
happens, until the very last statement in constructed() to add the
pending action.
The right way is IN6_ADDR_INIT_ANY.
While at it, don't initialize multiple variables in the same line.

The cast is bogus and leads to a compiler warning:

For static functions inside a module, the compiler determines on its own
whether to inline the function.
Also, "inline" was used at some places that don't immediatly look like
candidates for inlining. It was most likely a copy&paste error.
We named the types inconsistently:
- "p2p-wireless" ("libnm-core/nm-setting-p2p-wireless.h")
- "p2p" ("libnm/nm-p2p-peer.h")
- "p2p-wifi" ("src/devices/wifi/nm-device-p2p-wifi.h")
It seems to me, "libnm/nm-p2p-peer.h" should be qualified with a "Wi-Fi"
specific name. It's not just peer-to-peer, it's Wi-Fi P2P.
Yes, there is an inconsistency now, because there is already
"libnm/nm-access-point.h".
It seems to me (from looking at the internet), that the name "Wi-Fi P2P"
is more common than "P2P Wi-Fi" -- although both are used. There is also
the name "Wi-Fi Direct". But it's not clear which name should be
preferred here, so stick to "Wi-Fi P2P".
In this first commit only rename the files. The following commit will
rename the content.
NM_UTILS_LOOKUP_STR() uses alloca(). Partly to avoid the overhead of
malloc(), but more important because it's convenient to use. It does
not require to declare a varible to manage the lifetime of the heap
allocation.
It's quite safe, because the stack allocation is of a fixed size of only
a few bytes. Overall, I think the convenience that we get (resulting in
simpler code) outweighs the danger of stack allocation in this case. It's
still worth it.
However, as it uses alloca(), it still must not be used inside a (unbound)
loop and it is obviously a macro.
Rename the macros to have a _A() suffix. This should make the
peculiarities more apparent.
When STP is disabled, the bridge parameters 'priority', 'forward-delay',
'hello-time' and 'max-age' are irrelevant.
We already skip them when loading a connection profile from a ifcfg file.
Do the same when generating a connection from a configured device, in
order to possibly assume the connection.
...also when the connection is created at NetworkManager
startup to map an already configured bridge.
Ensure the device has configuration values that fall inside
NetworkManager boundaries, otherwise map the value with a default.
