Also add docstring, copyright notice.

Add <warnfilter> section, which allows you to configure Python warning filters in zope.conf.  Useful for suppressing the USELESS DeprecationWarnings that emanate from TALGenerator wrt i18n.

XXX thought I already checked this in.

zope33_devel branch at this time.

configuration file can be used for both the runzeo and zeoctl scripts.
This makes it easier to keep all the configuration needed to support the
ZEO server process in a single file.
For more explanation of the changes, see

Add the process ID to distinguish different processes when tests are

to boost the odds of success, and to prevent systematic favoring of any
thread.  That appears to work.

Synchronous is what matters for the tests.

Move two class variable definitions into __init__(), because class
variables defined in __slots__ are immutable.  This should still be a
net memory savings, because the a 8-entry dict and a 10-entry dict
both have the same allocated size.
