The main difference between "shared/nm-utils/nm-macros-internal.h" and
"shared/nm-utils/nm-shared-utils.h" is that the former is header-only
while the latter has a source file as well.
Apart from that, both headers are included everywhere.
The next commit will add nm_strstrip_avoid_copy_a() to
"nm-macros-internal.h" header, which will use nm_strndup_a().
Hence, also nm_strndup_a() should be in "nm-macros-internal.h".
"_str" is a very tempting name for a temporary variable.
Rename the variable in nm_strndup_a() macro, so that other macros can
call these (more general) macros (and still use the name "_str").
'sriov_drivers_autoprobe' was added in kernel 4.12. With previous
kernel versions NM is currently unable to set any SR-IOV parameter
because it tries to read 'sriov_drivers_autoprobe' which doesn't
exist, assumes that current value is -1 and tries to change it,
failing.
When the file doesn't exist, drivers are automatically probed so we
can assume the value is 1. In this way NM is able to activate a
connection with sriov.autoprobe-drivers=1 (the default) even on older
kernel versions.

The test will need more information to know why it may fail.
Return a NetworkManager error code, instead of a boolean.
For better or worse, our release builds commonly do not disable assertions.
That means,
- NDEBUG is not set, and assert() is in effect
- G_DISABLE_ASSERT is not set, and g_assert() is in effect
- G_DISABLE_CHECKS is not set, and g_return*() is in effect.
On the other hand, NM_MORE_ASSERTS is not enabled by default and nm_assert()
is stripped away. That is the actual purpose of nm_assert(): it is
commonly disabled on release builds, while all other assertions are
enabled.
Note that it is fully supported to build NetworkManager with all kind of
assertions disabled. However, such a configuration is not much tested
and I would not recommend it for that reason.
%meson expands to

thus passing -DNDEBUG to the meson build. Override that.
If we don't have explicit_bzero(), try a bit harder and use
a volatile pointer.
This is also what libsecret's egg_secure_clear() does [1]. However, for
us this is less important, because commonly we expect glibc to provide
a useable explicit_bzero().

When a device is removed (like when the user unplugs a usb network
device) the device object is removed, so it doesn't emit a notify signal
for a change in its connectivity and so, device_connectivity_changed
is not called. This means that nobody updates the global connectivity
value which is potentially wrong if the device was the one providing
network connectivity.
Since device_connectivity_changed's first two parameters aren't actually
used and are there just for the signal to be able to be connected, I
moved the code from device_connectivity_changed to a new
update_connectivity_value function that just takes a NMManager
parameter and also call it from remove_device.

When nmcli needs secrets for a connection it asks them for every known
setting. nmtui is a bit smarter and asks them only for settings that
actually exist in the connection. Make a step further and let clients
ask secrets only for setting that exist *and* have any secret
property. This decreases the number of D-Bus calls when editing or
showing a connection with secrets.

The 4th argument of AC_SEARCH_LIBS is a list of additional libraries,
not the name of the variable to hold the result which is always
ac_cv_search_$function. Also, we should ignore the result when it is
"none required".

Go straight to unmanaged. That's what all the other devices do when
their backing resources vanish. If the device reached disconnected
state, an autoconnect check would try to connect it back, in vain.

Open vSwitch is the special kid on the block -- it likes to be in charge of
the link lifetime and so we shouldn't be. This means that we shouldn't be
attempting to remove the link: we'd just (gracefully) fail anyways.
More importantly, this also means that we shouldn't care if we see the link
go away. Once the device reaches DISCONNECTED state, its configuration is
cleaned up and we may already be activating another connection. We shouldn't
alter the device state when OpenVSwitch decides to drop the old link.

initscripts support rule-* and rule6-* files for that.
Up until now, we ignored these files for the most part, except if
a user configured such files, the profile could not contain any static
routes (or specify a route-table setting). This also worked together
with the dispatcher script "examples/dispatcher/10-ifcfg-rh-routes.sh".
We cannot now start taking over that file format for rules. It might
break existing setups, because we can never fully understand all rules as
they are understood by iproute2. Also, if a user has a rule/rule6 file and
uses NetworkManager successfully today, then clearly there is a script
in place to make that work. We must not break that when adding rules
support.
Hence, store routing rules as numbered "ROUTING_RULE_#" and
"ROUTING_RULE6_#" keys.
Note that we use different keys for IPv4 and IPv6. The main reason is
that the string format is mostly compatible with iproute2. That means,
you can take the value and pass it to `ip rule add`.
However, `ip rule add` only accepts IPv4 rules. For IPv6 rules, the user
needs to call `ip -6 rule add`. If we would use the same key for IPv4
and IPv6, then it would be hard to write a script to do this.
Also, nm_ip_routing_rule_from_string() does take the address family as
hint in this case. This makes
ROUTING_RULE_1="pref 1"
ROUTING_RULE6_1="pref 1"
automatically determine that address families. Otherwise, such
abbreviated forms would be not valid.
Add NMIPRoutingRule API with a few basic rule properties. More
properties will be added later as we want to support them.
Also, add to/from functions for string/GVariant representations.
These will be needed to persist/load/exchange rules.
The to-string format follows the `ip rule add` syntax, with the aim
to be partially compatible. Full compatibility is not possible though,
for various reasons (see code comment).
