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.

Added note to documentation about copy_reg rename.

Renamed copy_reg to copyreg in the standard library, to avoid
spurious warnings and ease later merging to py3k branch. Public
documentation remains intact.

Factored the import guard in test_py3kwarn.TestStdlibRemovals into
a context manager, namely test_support.CleanImport.
