This is a conservative version of SF patch 504889. It uses the log module instead of calling print in various places, and it ignores the verbose argument passed to many functions and set as an attribute on some objects. Instead, it uses the verbosity set on the logger via the command line. The log module is now preferred over announce() and warn() methods that exist only for backwards compatibility. XXX This checkin changes a lot of modules that have no test suite and aren't exercised by the Python build process. It will need substantial testing.
