Previously, the -R option would be specified multiple times
if PYTHONHASHSEED was set.

Order of search is now:
  1. Try getattr
  2. If that throws an exception, check __dict__ directly
  3. If still not found, walk the mro looking for the eldest class that has
     the attribute (e.g. things returned by __getattr__)
  4. If none of that works (e.g. due to a buggy __dir__, __getattr__, etc.
     method or missing __slot__ attribute), ignore the attribute entirely.

I'll make sure and include them in future patches.

testing multiple embedding scenarios.

Skip tests for 24-bit wave file on big-endian platforms.

This adds EmailMessage and, MIMEPart subclasses of Message
with new API methods, and a ContentManager class used by
the new methods.  Also a new policy setting, content_manager.

Patch was reviewed by Stephen J. Turnbull and Serhiy Storchaka,
and reflects their feedback.

I will ideally add some examples of using the new API to the
documentation before the final release.

This allows different parts of a program to use different methods for
starting processes without interfering with each other.

and groups() methods of match object now always return a string or a bytes
object.
