neighbor: More gc_list changes

More gc_list changes and cleanups.

The first 2 patches are bug fixes from the first gc_list change.
Specifically, fix the locking order to be consistent - table lock
followed by neighbor lock, and then entries in the FAILED state
should always be candidates for forced_gc without waiting for any
time span (return to the eviction logic prior to the separate gc_list).

Patch 3 removes 2 now unnecessary arguments to neigh_del.

Patch 4 moves a helper from a header file to core code in preparation
for Patch 5 which removes NTF_EXT_LEARNED entries from the gc_list.
These entries are already exempt from forced_gc; patch 5 removes them
from consideration and makes them on par with PERMANENT entries given
that they are also managed by userspace.
====================

Externally learned entries are similar to PERMANENT entries in the
sense they are managed by userspace and can not be garbage collected.
As such remove them from the gc_list, remove the flags check from
neigh_forced_gc and skip threshold checks in neigh_alloc. As with
PERMANENT entries, this allows unlimited number of NTF_EXT_LEARNED
entries.

PERMANENT entries are not on the gc_list so the state check is now

====================
Introduce NETDEV_PRE_CHANGEADDR

Spectrum devices have a limitation that all router interfaces need to
have the same address prefix. In Spectrum-1, the requirement is for the
initial 38 bits of all RIFs to be the same, in Spectrum-2 the limit is
36 bits. Currently violations of this requirement are not diagnosed. At
the same time, if the condition is not upheld, the mismatched MAC
address ends up overwriting the common prefix, and all RIF MAC addresses
silently change to the new prefix.

It is therefore desirable to be able at least to diagnose the issue, and
better to reject attempts to change MAC addresses in ways that is
incompatible with the device.

Currently MAC address changes are notified through emission of
NETDEV_CHANGEADDR, which is done after the change. Extending this
message to allow vetoing is certainly possible, but several other
notification types have instead adopted a simple two-stage approach:
first a "pre" notification is sent to make sure all interested parties
are OK with the change that's about to be done. Then the change is done,
and afterwards a "post" notification is sent.

This dual approach is easier to use: when the change is vetoed, nothing
has changed yet, and it's therefore unnecessary to roll anything back.
Therefore this patchset introduces it for NETDEV_CHANGEADDR as well.

One prominent path to emitting NETDEV_CHANGEADDR is through
dev_set_mac_address(). Therefore in patch #1, give this function an
extack argument, so that a textual reason for rejection (or a warning)
can be communicated back to the user.

In patch #2, add the new notification type. In patch #3, have dev.c emit
the notification for instances of dev_addr change, or addition of an
address to dev_addrs list.

In patches #4 and #5, extend the bridge driver to handle and emit the
new notifier.

In patch #6, change IPVLAN to emit the new notifier.

Likewise for bonding driver in patches #7 and #8. Note that the team
driver doesn't need this treatment, as it goes through
dev_set_mac_address().

In patches #9, #10 and #11 adapt mlxsw to veto MAC addresses on router
interfaces, if they violate the requirement that all RIF MAC addresses
have the same prefix.

Finally in patches #12 and #13, add a test for vetoing of a direct
change of a port device MAC, and indirect change of a bridge MAC.

Pass extack to SWITCHDEV_PORT_OBJ_ADD

Drivers may need to do validation as a result of port object addition.
An example is mlxsw, which needs to check the configuration of a VXLAN
device attached to an offloaded bridge. Without a mapped VLAN, the
invalidity of the device is not important, but as soon as a pvid,
untagged VLAN is configured for the device, it has to be validated and
offloaded. Should the validation fail, there's currently no way to
communicate details of the failure to the user, beyond an error number.

Because currently, extack is not available at all in that area of code,
this patch starts down at the RTNL level and progresses up towards the
driver(s).

In patch #1, ndo_bridge_setlink is updated to include extack, and
callbacks of all clients are updated as well (ignoring the argument).

In patch #2, the bridge driver is updated to propagate the extack
through to the switchdev border, br_switchdev_port_vlan_add().

Patches #3, #4 and #5 then gradually extend switchdev to pass the extack
argument through to the switchdev blocking notifier chain.

Patches #6 and #7 then update mlxsw to pass the extack argument from
VXLAN events resp. port events on to mlxsw_sp_bridge_8021q_vxlan_join().

Finally in patches #8 and #9, the code paths from the previous two
patches are verified to yield an error message.

v2:
- Patch #1:
    - In ndo_bridge_setlink(), keep the whole extack declaration on the
      same line.
