During testing and code inspection, there were various anti-patterns on this (and U-Blox driver) codebase(s), including obfuscation, and lack of data validation. This made it increasingly difficult to introduce further variants of u-blox GNSS modems. With this patch, both the UBX modem and the M8 driver have been refactored to ease the reliability and maintainability of these codebases. Here are some highlights: WRT UBX modem: - Helper macros to easily create UBX frames, (including checksum calculation), at compile time; thus, making it easier to extend UBX commands. - Logic validation by the inclusion of the modem_ubx testsuite, used to refactor the code through TDD. - Ability to receive unsolicited messages, in order to enable U-Blox drivers to rely on modem_ubx to transceive all commands, and avoid hopping between modem_ubx and modem_chat. WRT M8 driver: - Remove GNSS specific protocol header files. Instead, unify them under modem/ubx/protocol.h. Background: After a survey and looking at ubxlib SDK I conclude the UBX protocol is by definition a GNSS protocol (there are non-GNSS u-blox modems, but they're not interfaced through UBX protocol). - Establish pattern to create and send/receive commands using new foundations on modem ubx. - Remove dependency of Modem chat, and instead use UBX unsolicited messages to get Navigation and Satellites data. - Switch from the auto-baudrate detection pattern to a pattern of transitioning between an initial known baudrate to a desired baudrate, in order to improve initialization time. - Add dts property to configure default fix-rate.
