and provide a substitute if the import fails, because pyclbr sees the
class definition.  Changed to ignore such cases' base classes and methods,
since they will not match.

pydoc now supports PEP 302 importers, by way of utility functions in
pkgutil, such as 'walk_packages()'.  It will properly document
modules that are in zip files, and is backward compatible to Python
2.3 (setuptools installs for Python <2.5 will bundle it so pydoc
doesn't break when used with eggs.)

What has not changed is that pydoc command line options do not support
zip paths or other importer paths, and the webserver index does not
support sys.meta_path.  Those are probably okay as limitations.

Tasks remaining: write docs and Misc/NEWS for pkgutil/pydoc changes,
and update setuptools to use pkgutil wherever possible, then add it
to the stdlib.

and test_threading_local no longer reports leaks under -R.  Thanks

This revision strips all the PEP 302 emulation code from runpy,
replacing it with published API classes and functions in pkgutil,
mostly using setuptools' implementation of common functionality,
but adding features from runpy, and doing some refactoring to make
the layer pydoc needs easier to implement on top of this.

One step down, four to go, although step #4 (adding C versions of
the new APIs to 'imp') may not be able to make it in time for
alpha 2.  We'll see how that goes.

configure time. The current check is too strict and doesn't allow building
extensions that can only run on newer versions of the OS than the version
python was build for, that is python build for 10.3 or later and an extension
for 10.4. This patch relaxes this check.

This turned out to be a reimplementation of patch 1193190.

the above command did not look for pyconfig.h, but the
bug is really in the look-up code: expecting to find it
in os.curdir is a rather fragile idea.
