Patch #1464708 from William McVey: fixed handling of nested comments in mail
addresses.  E.g.

"Foo ((Foo Bar)) <foo@example.com>"

Fixes for both rfc822.py and email package.  This patch needs to be back
ported to Python 2.3 for email 2.5.

UNIX platforms.

Fix another problem in inspect: if the module for an object cannot be found, don't try to give its __dict__ to linecache.

On the way, add a decorator to test_support to facilitate running single
test functions in different locales with automatic cleanup.

find a better place for the link to it than alongside bsddb & friends.

add expat_config.h.

them to the Error errors list.

Printing to stdout, doesn't mean the data was actually written.
It depends on the buffering, so we need to flush.  This will hopefully
really fix the buildbots getting killed due to no output on the slow bots.

(since they won't trigger if zlib is already sucessfully imported); they
were found by grepping .py files, instead of looking at warning output :)

 - Warn-raise ImportWarning when importing would have picked up a directory
   as package, if only it'd had an __init__.py. This swaps two tests (for
   case-ness and __init__-ness), but case-test is not really more expensive,
   and it's not in a speed-critical section.

 - Test for the new warning by importing a common non-package directory on
   sys.path: site-packages

 - In regrtest.py, silence warnings generated by the build-environment
   because Modules/ (which is added to sys.path for Setup-created modules)
   has 'zlib' and '_ctypes' directories without __init__.py's.
