When no slave is present, dynamic IP configuration (DHCPv4, DHCPv6,
IPv6 autoconf) cannot proceed. But static and link-local
configuration can. So if IPv4 requires DHCP but IPv6 is static,
it makes no sense to block IPv6 configuration from proceeding
just because DHCPv4 cannot.

If, for example, a bond interface has dynamic IPv4 configuration
and static IPv6 configuration, then without slaves IPv6 config
can proceed but IPv4 cannot until a slave is present. Allow
subclasses to postpone a specific IP configuration path until
they're ready, but let others proceed.
We don't need to check device state here because the manager, which
is the only thing that calls nm_device_activate() in
internal_activate_device() ensures that the device is deactivated
before starting a new activation request.
Allows to attach any connection to a bridge using the BRIDGE= key.
IP configuration is optional for bridge components but not
prohibited. Test case included.
Provides functions to create and delete bridging devices and
to attach/detach slaves from bridging devices.
It currently relies on the ioctl() kernel interface. The long
term goal is to use the netlink interface for this.
This function gets used for both /proc/sys (ie, sysctl) and for
sysfs attributes. There are two issues with it:
1) most sysctl values don't care about a trailing LF, but some
sysfs attributes (infiniband) do; so we always have to add the
trailing LF. Just move that into the function to ensure that
callers don't forget to add it.
2) neither sysfs or sysctl support partial writes, while the
existing function did partial writes. Practically, both the
write handlers for sysfs and sysctl should always handle all
the data, but if they don't, partial writes are wrong. So
instead, try three times to write all the data.
Can't leave the backup files lying around when doing 'make distcheck',
so when backup up a file, return the backup file path so that the
caller can (optionally) remove it.
If the certificate path from the supplicant config is not absolute,
we need to make it absolute. When building with a different builddir,
the certificate from the supplicant config is actually in the srcdir,
but the builddir is the current PWD.
Recent automake versions switched to not creating empty directories,
but at the moment NetworkManager g_warning()s on startup if it doesn't
find $(pkglibdir). So let's make it.

(core: move DNS change handling to the policy and optimize DNS updates (bgo #676778))
It consolidated DNS update handling, but mistakenly removed hostname changing
from NM_DEVICE_STATE_ACTIVATED state handler.

When enumerating devices, libgudev's matching by default will return
devices which udev has not yet finished initializing.
This was frequently causing boot-time races on the OLPC XO, where
NetworkManager would bring a device up before udev had renamed it,
causing the later rename to fail.
To solve this, filter the enumeration matches to only include
initialized devices. The devices that are present but uninitialized
at this time will arrive a short time later, via a uevent.

(dcbw: update gudev version check in configure.ac)
Until we remove libnl-1.x and libnl-2.x support, it should be
possible to choose the libnl version at build time. This is
mostly important for testing legacy libnl support but it also
helps distributions that ship other tools built agains them.

Instead of a 'modem#' identifier, use the primary port of the modem as unique
identifier. The modem UID will be set afterwards as the Device Iface, which is
then used by libnm-glib to gather vendor/product string from the udev device
associated with the Device Iface; so it really needs to be a real port.
Trying to ARP with no other machines in the broadcast domain
is pretty pointless, and in many cases doesn't work (ZTE MF691
/T-Mobile Rocket 2), so turn it off.
The only case where this was being used was in PPP-based connections, as the
ppp0 interface was reported by pppd once the IP setup was done. Instead, just
update the 'NM_MODEM_DATA_PORT' property, as the NMDevices already listen for
changes in that property.
The new ModemManager1-based `NMModemBroadband' objects will set the data port
information only after having created the bearer as part of the connection
process. The devices, therefore, need to listen to changes in the `data-port'
property, so that the `ip-iface' in the `NMDevice' is set before finishing the
stage1 of the activation. This is required in order to have a proper ifup of the
data port.
G_TYPE_INSTANCE_GET_PRIVATE() is known to be slow, so just call it once when
the private data is created, and keep a 'priv' pointer around for easy access.
The new `MMManager' object takes care of notifying modems added or removed from
the ModemManager1 interface.
We will listen to both the old and new ModemManager implementations, but as soon
as the first ModemManager implementation is found, the other one gets cleared,
so that we don't wait forever to appear.
The new ModemManager comes with its own headers, and defines its own symbols to
name e.g. each interface. In order not to collide with the new ones, rename the
existing ones with a 'MM_OLD_DBUS' prefix instead of just 'MM_DBUS'.
The new switch will run in 'auto' mode when not explicitly specified. In this
case the new ModemManager1 support will only be available if it finds libmm-glib
through pkg-config.
Other than the 'auto' mode, 'yes' and 'no' are allowed in order to specify
explicit requirements.
Previously, when a new bond or VLAN connection was created, NM would
always create the virtual device right away. But on startup, it only
creates virtual devices for connections that can autoconnect. Fix
connection_added() to make that check as well.
The Gentoo initscript is being patched downstream anyway. It
will be easier to maintain it in just one place.

This patch makes DHCPv6 support more or less equivalent to that
one of IPv4 DHCP.
(dcbw: fix some formatting, rearrange code so it's less convoluted,
fix up writing hostname to ifcfg files)
