Extract methods from sdist.add_defaults, allowing subclasses to override or inject different behaviors.

Issue #19544 and Issue #6516: Restore support for --user and --group parameters to sdist command as found in Python 2.7 and originally slated for Python 3.2 but accidentally rolled back as part of the distutils2 rollback. Closes Issue #6516.

sdist used to crash with a full traceback dump instead of printing a
nice warning with the faulty line number.

sdist used to crash with a full traceback dump instead of printing a
nice warning with the faulty line number.

The changed behavior of sdist in 3.1 broke packaging for projects that
wanted to use a manually-maintained MANIFEST file (instead of having a
MANIFEST.in template and letting distutils generate the MANIFEST).

The fixes that were committed for #8688 (76643c286b9f by Tarek and
d54da9248ed9 by me) did not fix all issues exposed in the bug report,
and also added one problem: the MANIFEST file format gained comments,
but the read_manifest method was not updated to handle (i.e. ignore)
them.  This changeset should fix everything; the tests have been
expanded and I successfully tested the 2.7 version with Mercurial, which
suffered from this regression.

I have grouped the versionchanged directives for these bugs in one place
and added micro version numbers to help users know the quirks of the
exact version they’re using.

Initial report, thorough diagnosis and patch by John Dennis, further
work on the patch by Stephen Thorne, and a few edits and additions by
me.

was forgotten in Tarek’s first changeset.

Fix closes Issue11439 Remove the SVN keywords from the code as it is no longer applicable in hg. Patch Contributed by Neil Muller.

reverted distutils its 3.1 state. All new work is now happening in disutils2, and distutils is now feature-frozen.
