Unicode filenames instead of bytes filenames to not depend on the ANSI code
page anymore and to support any filename.

Also, as in importlib, append the id of an object to make the file name
pseudo-random.

Logging replaces verbose arguments.  I haven’t fixed the example in
Doc/install/install.rst because I have major fixes and changes to the
oc under way and will fix or remove that example as part of that task.

Backout of 2e047702df7f.  Reported by Jeremy Kloth.

Tarek’s commit fixed the way packaging configuration file markers are
split under Windows, but these two files were not edited.

I haven’t updated NEWS for every change or fix in packaging, thinking
that the only entry we need for 3.3a1 is “Add packaging module to the
stdlib”.  Other developers have however added entries for these fixes,
but I don’t think they are interesting for users.

Note that the distutils2 backport has a full changelog.

- Don't use keyword arguments for debug_override; I find it more
  readable to have a comment explaining that True makes pyc and False
  pyo than to write out the non-obvious (when you haven’t read the doc)
  argument name

- Move duplicate code from build_py and install_lib into cmd

- Remove obsolete verbose argument of util.byte_compile

- Remove obsolete passing of -O/-OO to the Python process spawned by
  util.byte_compile (I’ll remove the whole spawning later, after I write
  more tests to check the contents of pyc and pyo files; now that
  byte_compile does not depend on the value of __debug__ in the calling
  Python, we can call py_compile or compileall directly)
