Configuration functions for the logging package for Python. The core package
is based on PEP 282 and comments thereto in comp.lang.python, and influenced
by Apache's log4j system.

Read the logging configuration from a ConfigParser-format file.
This can be called several times from an application, allowing an end user
the ability to select from various pre-canned configurations (if the
developer provides a mechanism to present the choices and load the chosen
configuration).

When (re)configuring logging, handle loggers which were in the previous
configuration but are not in the new configuration. There's no point
deleting them as other threads may continue to hold references to them;
and by disabling them, you stop them doing any logging.
However, don't disable children of named loggers, as that's probably not
what was intended by the user. Also, allow existing loggers to NOT be
disabled if disable_existing is false.

Start up a socket server on the specified port, and listen for new
configurations.
These will be sent as a file suitable for processing by fileConfig().
Returns a Thread object on which you can call start() to start the server,
and which you can join() when appropriate. To stop the server, call
stopListening().
Use the ``verify`` argument to verify any bytes received across the wire
from a client. If specified, it should be a callable which receives a
single argument - the bytes of configuration data received across the
network - and it should return either ``None``, to indicate that the
passed in bytes could not be verified and should be discarded, or a
byte string which is then passed to the configuration machinery as
normal. Note that you can return transformed bytes, e.g. by decrypting
the bytes passed in.
