Changed an import, replaced md5.new() with md5(), and added an encode where needed.

 - relative imports
 - keyword-only arguments
 - function annotations
 - class decorators
 - raise ... from ...
 - except ... as ...
 - nonlocal
 - bytes literals
 - set literals
 - set comprehensions
 - dict comprehensions
Removals:

Some of this should be backported to 2.x.

  Fix some shallow bugs in Demo/parser/unparse.py, and add tests:

    - insert commas between entries in del statement
    - left and right shifts were represented as >> and << (respectively); reverse
    - unindent properly after for: else:  or while: else:
    - add parens around the result of an unary operation
    - add parens around negative numbers, to avoid turning (-1)**2 into -1**2.

  Fix Issue8653 - Docstring for urlunsplit function.
........

Required updating code relying on other modules to switch to _bootstrap's
unique module requirements. This led to the realization that
get_code was being too liberal in its exception catching when calling set_data
by blindly grabbing IOError. Shifted the responsibility of safely ignoring
writes to a read-only path to set_data.

Importlib is still not relying on SourceLoader yet; requires creating a
SourcelessLoader and updating the source finder.

  DeprecationWarning is now silent by default.

  This was originally suggested by Guido, discussed on the stdlib-sig mailing
  list, and given the OK by Guido directly to me. What this change essentially
  means is that Python has taken a policy of silencing warnings that are only
  of interest to developers by default. This should prevent users from seeing
  warnings which are triggered by an application being run against a new
  interpreter before the app developer has a chance to update their code.

  Closes issue #7319. Thanks to Antoine Pitrou, Ezio Melotti, and Brian Curtin
  for helping with the issue.

  The silencing of DeprecationWarning was not taking -3 into consideration. Since
  Py3K warnings are DeprecationWarning by default this was causing -3 to
  essentially be a no-op. Now DeprecationWarning is only silenced if -3 is not
  used.

  Closes issue #7700. Thanks Ezio Melotti and Florent Xicluna for patch help.

SourceLoader is a simplification of both PyLoader and PyPycLoader. If one only
wants to use source, then they need to only implement get_data and
get_filename. To also use bytecode -- sourceless loading is not supported --
then two abstract methods -- path_mtime and set_data -- need to be implemented.
Compared to PyLoader and PyPycLoader, there are less abstract methods
introduced and bytecode files become an optimization controlled by the ABC and
hidden from the user (this need came about as PEP 3147 showed that not treating
bytecode as an optimization can cause problems for compatibility).

PyLoader is deprecated in favor of SourceLoader. To be compatible from Python
3.1 onwards, a subclass need only use simple methods for source_path and
is_package. Otherwise conditional subclassing based on whether Python 3.1 or
Python 3.2 is being is the only change. The documentation and docstring for
PyLoader explain what is exactly needed.

PyPycLoader is deprecated also in favor of SourceLoader. Because PEP 3147
shifted bytecode path details so much, there is no foolproof way to provide
backwards-compatibility with SourceLoader. Because of this the class is simply
deprecated and users should move to SourceLoader (and optionally PyLoader for
Python 3.1). This does lead to a loss of support for sourceless loading
unfortunately.

At some point before Python 3.2 is released, SourceLoader will be moved over to
importlib._bootstrap so that the core code of importlib relies on the new code
instead of the old PyPycLoader code. This commit is being done now so that
there is no issue in having the API in Python 3.1a1.
