Gris Ge 02c34d538c bridge: skip VLAN filtering resetting in reapply if no vlan change changed 
When doing reapply on linux bridge interface, NetworkManager will reset
the VLAN filtering and default PVID which cause PVID been readded to all
bridge ports regardless they are managed by NetworkManager.

This is because Linux kernel will re-add PVID to bridge port upon the
changes of bridge default-pvid value.

To fix the issue, this patch introduce netlink parsing code for
`vlan_filtering` and `default_pvid` of NMPlatformLnkBridge, and use that
to compare desired VLAN filtering settings, skip the reset of VLAN
filter if `default_pvid` and `vlan_filtering` are unchanged.

libnm-platform

A static helper library that provides NMPlatform and other utils. This is NetworkManager's internal netlink library, but also contains helpers for sysfs, ethtool and other kernel APIs.

NMPlaform is also a cache of objects of the netlink API: NMPCache and NMPObject. These objects are used throughout NetworkManager also for generally tracking information about these types. For example, NMPlatformIP4Address (the public part of a certain type of NMPObject) is not only used to track platform addresses from netlink in the cache, but to track information about IPv4 addresses in general.

This depends on the following helper libraries
