In the past, nmp_lookup_init_object() could both lookup all object for a
certain ifindex, and lookup all objects of a type. That fallback path
already leads to an assertion failure fora while now, so nobody should
be using this function to lookup all objects of a certain type (for
what, we have nmp_lookup_init_obj_type()).
Now, remove the fallback path, and rename the function to what it really
does.
ASSUME is causing more troubles than benefits it provides. This patch is
dropping NM_L3_CFG_COMMIT_TYPE_ASSUME and assume_config_once. NM3LCfg
will commit as if the sys-iface-state is MANAGED.
This patch is part of the effort to remove ASSUME from NetworkManager.
After ASSUME is dropped when starting NetworkManager it will take full
control of the interface, re-configuring it. The interface will be
managed from the start instead of assumed and then managed.
This will solve the situations where an interface is half-up and then a
restart happens. When NetworkManager is back it won't add the missing
addresses (which is what assume does) so the interface will fail during
the activation and will require a full activation.

(cherry picked from commit bf5927b978)
We don't run glib-mkenums for certain sources like "core" and
"libnm-glib-aux".
These annotations have no effect. Drop them.
They also mess with the automated formatting.
We use clang-format for automatic formatting of our source files.
Since clang-format is actively maintained software, the actual
formatting depends on the used version of clang-format. That is
unfortunate and painful, but really unavoidable unless clang-format
would be strictly bug-compatible.
So the version that we must use is from the current Fedora release, which
is also tested by our gitlab-ci. Previously, we were using Fedora 34 with
clang-tools-extra-12.0.1-1.fc34.x86_64.
As Fedora 35 comes along, we need to update our formatting as Fedora 35
comes with version "13.0.0~rc1-1.fc35".
An alternative would be to freeze on version 12, but that has different
problems (like, it's cumbersome to rebuild clang 12 on Fedora 35 and it
would be cumbersome for our developers which are on Fedora 35 to use a
clang that they cannot easily install).
The (differently painful) solution is to reformat from time to time, as we
switch to a new Fedora (and thus clang) version.
Usually we would expect that such a reformatting brings minor changes.
But this time, the changes are huge. That is mentioned in the release
notes [1] as
Makes PointerAligment: Right working with AlignConsecutiveDeclarations. (Fixes https://llvm.org/PR27353)

Problem: if l3cfg commits an address and routes from DHCP, when the
address expires those objects are removed automatically. NM tracks the
objects as missing as if the user removed them. This is to prevent
l3cfg to committing them again. If the lease if renewed, l3cfg should
be allowed to commit those objects again.
Introduce a l3cd flag to indicate that it should be force-committed
once, and propagate this flag to platform objects. In this way, l3cfg
can avoid committing again objects that are removed externally, but it
can commit them when the l3cd changes.

NMPlatformIP{Address,Route} are mainly the structs that we receive via
netlink and get cached in the NMPlatform cache.
However, the same structures are also used by the upper layers to track
which addresses to add.
Add a flag to addresses and routes, for a certain behavior, relevant
during NML3Cfg commit. The idea is that during commits for NML3Cfg of
type NM_L3_CFG_COMMIT_TYPE_ASSUME, no new addresses are added that
are not already configured. In some cases, we want to override that,
and need a flag to track that. More about that later.
It can be convenient to track a NMPObject in form of their down-cast
pointers. When doing that, it's useful to have clear/ref-set helpers
that operate on such pointers and up-cast first.
