Rebased cmake-staging branch (post PRs 45 and 34)

[hebasto]

This is the cmake-staging branch rebased on the recent bitcoin/master one with the squashed "!fixup" commits.

Steps to reproduce:

1. Apply the git rebase -i --autosquash master command (must be no conflicts).
2. Mirror build system changes from net: improves addnode / m_added_nodes logic bitcoin/bitcoin#28155.

Quick local build is ok.
