Major rewrite for Multi-Node and DBus

The Mesh Daemon has been largely rewritten.

It matches the API in doc/mesh-api.txt, and is now accessible from non- privledged DBus clients. The commandline version has been temporarily removed, although it will probably be re-added in the future. The dBus privledges need to be adjusted to allow for non-privledged access to Daemon interfaces. We will shortly also be adding a Mesh Specific README and TODO file, but in the meantime, contact Brian and/or Inga with any questions.

v6 -- Address Marcel's v5 comments, including cleanup, and unstacking include files. There was also some compression of commits, where little was being actually done. Other big difference with patch set is a more verbose explanation of non-trivial commits, particularily where functionality was removed (or deleted) in favor of rewrites in other (mostly new) files. This is especially true of Provisioning which has been largely rewritten for both readability and for focus.

Tested on TIP of upstream/master as of 28-Dec-2018, on Fedora 27, 28 and 29, with both ./bootstrap-configure, and distcheck.
