This fixes errors like:
- ConnectorException: makeListeningConnection on ('127.0.0.1', 33157) failed: 98:Address already in use
  Error executing './neomaster ...
- "error: [Errno 22] Invalid argument" in __allocatePort

A system-wide lock is used to prevent conflicts when several NEO test suites are
run simultaneously.

However, errors could still happen if other software tries to allocate ports.
Allocated ports are kept open as long as possible to minimize the probability
that it happens: they are closed just before spawning subprocesses.

It will be used to allocate ports in a safer way.

We add this doc file to explain how to check the progressing of neo
test suite(unit tests) and to know how to control which neo parts
had been tested and which had not.

To allow Neo to be installed on a machine through buildout, we must define
buildout.cfg file. We added this fils to make it possible to set up a neo buildout on a machine
directly with repository sources. It is now possible to install neo on a computer
just by using buildout, linked to neo eggs.

This is required since r2534, but was omitted from repository (patch was
posted on zodb-dev, awaiting review).

Use a marker meaning "no content", AF_UNSPEC seems appropriate for this
kind of usage.

In order to correct some test errors generated by IPv6 support on Neo. These
errors were dued to mis-implemented tests, which were attempted wrong type
of exceptions.

In order to synchronise neo with slapos, it has to work perfectly with ipv4
and ipv6. This allows to integrate neo in erp5 and to prepare different buildout
installations of neo.
The protocol and connectors are no more generic but can now support IPv4 and
IPv6 connections. We adopted a specific way of development which allow to
easily add new protocols in the future.

- Storage nodes start to replicate a partition when all transactions that were
pending when the oudated partition was added are committed.
- Transactions are registered by the master from the tpc_begin step.

Move queue flushing to dispatcher.
Use forget_queue in "undo" as well.

Instead, forget them at dispatcher level, and empty queue (in case
answers were received but not handled yet).

Since r2357 "ask" atomically checks connection state before sending, so early
check & locking are not needed here anymore.
