NFC refactoring (#3050)
"A long time ago in a galaxy far, far away...." we started NFC subsystem refactoring.

Starring:

- @gornekich - NFC refactoring project lead, architect, senior developer
- @gsurkov - architect, senior developer
- @RebornedBrain - senior developer

Supporting roles:

- @skotopes, @DrZlo13, @hedger - general architecture advisors, code review
- @Astrrra, @doomwastaken, @Hellitron, @ImagineVagon333 - quality assurance

Special thanks:

@bettse, @pcunning, @nxv, @noproto, @AloneLiberty and everyone else who has been helping us all this time and contributing valuable knowledges, ideas and source code.
