platform: make FOR_EACH_DELAYED_ACTION() robust against integer overflow 
Currently there is no problem. However, DelayedActionType is a packed
enum, and if we add a few more enum values, it might happen that
DELAYED_ACTION_TYPE_MAX is 0x8000 and DelayedActionType effectively
uint16_t.

When that happens, the code would become an infinite loop, because
0x8000 is not larger than DELAYED_ACTION_TYPE_MAX, but `<<= 1`
shifts out the bit, making it zero.

Avoid that.

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
