This patch removes the dependency on the Carbon package from urllib.
The mac-specific code for getting proxy configuration is now writting in
Python using ctypes and uses the SystemConfiguration framework instead of
InternetConfig. Also provides a mac-specific implementation of proxy_bypass.

The 'mac' platform (that is, os.name == 'mac') was used for the MacOS 9 port,
which is no longer supported (as of Python 2.4 IIRC).

was renamed.

Renamed socketserver module in its own documentation.
Renamed documentation references.

Deprecated old name.

  ``Completer.complete()`` method are now caught and ignored.

Modified TestStdlibRenames to support platform specific renames.
Added test for PixMapWrapper rename warning.
Added note to documentation about PixMapWrapper rename.

Added note to documentation about Queue rename.

Adds 'n' as a format specifier for integers, to mirror the same
specifier which is already available for floats.  'n' is the same as
'd', but inserts the current locale-specific thousands grouping.

I added this as a stringlib function, but it's only used by str type,
not unicode.  This is because of an implementation detail in
unicode.format(), which does its own str->unicode conversion.  But the
unicode version will be needed in 3.0, and it may be needed by other
code eventually in 2.6 (maybe decimal?), so I left it as a stringlib
implementation.  As long as the unicode version isn't instantiated,
there's no overhead for this.

Use the 3.0 module name to avoid spurious warnings.

Thanks to Matt Harden.
