33bfbe109e Chain manager bug fixes & enhancment (more...) 
* Set max length of a chain at -define(MAX_CHAIN_LENGTH, 64).

* Perturb tick sleep time of each manager

* If a chain manager L has zero members in its chain, and then its local
public projection store (authored by some remote author R) has a projection
that contains L, then adopt R's projection and start humming consensus.

* Handle "cross-talk" across projection stores, when chain membership
is changed administratively, e.g. chain was [a,b,c] then changed to merely
[a], but that change only happens on a.  Servers b & c continue to use
stale projections and scribble their projection suggestions to a, causing
it to flap.

What's really cool about the flapping handling is that it *works*.  I
wasn't thinking about this scenario when designing the flapping logic, but
it's really nifty that this extra scenario causes a to flap and then a's
inner projection remains stable, yay!

* Add complaints when "cross-talk" is observed.

* Fix flapping sleep time throttle.

* Fix bug in the machi_projection_store.erl's bookkeeping of the
max epoch number when flapping.

Introduce machi_flu_psup:start_flu_package/4 as a way to start all
related FLU processes
    * The projection store
    * The chain manager
    * The FLU itself

... as well as linked processes.
http://www.snookles.com/scotttmp/flu-tree-20150430.png shows one FLU
running, "a".  The process registered "a" is the append server,
"some-prefix" for the sequencer & writer for the current <<"some-prefix">>
file, and a process each for 3 active TCP connections to that FLU.

quite a bit there that's "cluster of clusters" stuff and not
appropriate for the current short-term work.
