Ensure that ZServer startup messages make it to the logfile and to stdout if we're running in debug mode.

Fix some stale comments.

Do a bit of cleanup in __init__ (add explanatory comments, move side-effect functions to a utility module).

refers to 'if len(step) == 0').

Default to zdrun daemon status "on" (effectively prevents signals from reaching child processes).  This will prevent the symptom of killing the server when pressing ctrl-C from an interactive logtail.

Also ignore child process return statuses.  If we don't, an interactive zopectl shell can clutter up the process table with zombies after a few starts and stops.

Dont write trailing newline into version.txt (causes problems because the version.txt is injected into a header sent from Zope and the newline causes Apache proxies to choke).

- added assignments to "document" the names exported by this module,

  when using Python 2.3.  (In Python 2.3, setting an attribute of a
  module outside of the module's implementation, where the name of the
  attribute matches the name of a built-in and the name isn't already
  defined in the module, causes a warning to be generated.)

an integer to avoid an unhelpful deprecation warning.  (Before Python
2.3, range() and many other built-in functions accepted floats as ints
"by accident"; those cases now generate warnings when passes a float.)

same output for both Python 2.2 and 2.3.

Python 2.3 changes the str() of KeyError exceptions to return a repr()
of the key instead of the str() of the key, which caused quotes to be
generated if we don't pick out just the key.

These warnings are displayed when running the unit tests.
This patch fixes the occurrances that are triggered by the unit tests;
there are probably others.
