Deferred client-connect patch set

Fabian submitted the original patch set in 2015. When I started working on it I had quite big rebase conflicts and decided to rebsae it manually. During this rebase I adjusted the code and made other minor and major adjustments to the code to better fit our current code style. The minor adjustments are mostly not mentioned in the commit message. The larger changes are mentioned or if feasible and sensible in their own commits.

The V4 patch fixes minor code style problems, spotted by uncrustify. Since modifying the first patch creates merge conflicts in all other patches, the whole patch series is rebased and resend. The patches themsevles do not have a V4 item in them that mentions this reformatting.
