Bluetooth device hardware addresses won't change during the lifetime
of the object (since that would mean a completely new device) and
they also won't have an ifindex because they aren't netdevices.
Various bits of the core periodically call nm_device_update_hw_address()
to update a device's hardware address, but this function expects that
any device with a hardware address also has an ifindex. Except that
Bluetooth devices don't because they aren't netdevices.
Modify the get_hw_address_length() function to return a boolean
indicating whether or not the address can ever change, and set that
for BT devices. nm_device_update_hw_address() then exits early if
there's no point in re-checking the hardware address, avoiding the
assertion.

'NM_DEVICE_IP_IFACE' has never been a writable property, just skip it and
explicitly call 'nm_device_set_ip_iface()' when the modem is managed by the old
ModemManager.

This is really, really old 2007-era code. Any NMDevice that gets
created is already supported, so there's no reason to have every
device set NM_DEVICE_CAP_NM_SUPPORTED. For those subclasses that
only set that capability, we can remove the subclass method
entirely. Next, it turns out that the "type capabilities" code
wasn't used anywhere, so remove that too. Lastly, "cipsec"
interfaces haven't been used on linux in about 5 years (they
were created by the Cisco binary-only IPSec kernel module for
Cisco VPNs long before vpnc and openswan came around) so we can
remove that code too.
Change the way that nm-properties-changed-signal works, and parse the
dbus-binding-tool-generated info to get the exact list of properties
that it's expected to export.
This makes NM_PROPERTY_PARAM_NO_EXPORT unnecessary, and also fixes the
problem of properties like NMDevice:hw-address being exported on
classes where it shouldn't be.
