[common] add `SerialNumber::Is{Greater/Less}>()` (#7334)
This commit adds `SerialNumber` class which provides `static` methods
`IsGeater<UintType>()` and `IsLess<UintType()` to compare two serial
numbers, taking into account the wrapping of serial number values
(similar to RFC-1982). This is then used in `MleRouter` and other
modules. This helps us avoid casting of `uint` to `int` for the
comparison (such a casting is undefined behavior in C++11 though
toolchains often implement it as expected). This commit also adds a
unit test `test_serial_number` to validate the new methods.
OpenThread released by Google is...
...an open-source implementation of the Thread networking protocol. Google Nest has released OpenThread to make the technology used in Nest products more broadly available to developers to accelerate the development of products for the connected home.
...OS and platform agnostic, with a narrow platform abstraction layer and a small memory footprint, making it highly portable. It supports both system-on-chip (SoC) and network co-processor (NCP) designs.
...a Thread Certified Component, implementing all features defined in the Thread 1.1.1 specification, including all Thread networking layers (IPv6, 6LoWPAN, IEEE 802.15.4 with MAC security, Mesh Link Establishment, Mesh Routing) and device roles, as well as Border Router support.
