An implementation of BIP9.

Unnecessary but good-to-have dependencies:

~~- [ ] Interface for chain.o #7563~~ ~~- [ ] BIP113 ready for trivial deployment #7565~~

TODO:
- GetMinerNextVersion()
- warnings when undefined (for you) rule changes are locked_in/activated according to bip9 rules.
- Unittests
EDIT: Use BIP68 + BIP112 as example deployment instead of BIP113.

BIP9: Introduce consensus/interfaces.h with CVersionBitsCacheInterface

This file is intended to be compatible with a C API, thus uses simple
structs and function pointers instead of C++ classes and methods.
