This is a temporary kludge and all is well in 3.3.

Patch by Hallvard B Furuseth.

- Issue #9651: Fix a crash when ctypes.create_string_buffer(0) was passed to file.write()
- Issue #11241: subclasses of ctypes.Array can now be subclassed.

some functions like file.write().

Windows does set the errno attribute to ENOENT, but the error message
displays the Windows error number (3 -> ERROR_PATH_NOT_FOUND), not the
errno number (2 -> ENOENT).
The Unix errno corresponding to 3 is ESRCH, explaining the confusion,
which can be seen in the following snippet:

>>> shutil.rmtree("foo")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "Z:\default\lib\shutil.py", line 272, in rmtree
    onerror(os.listdir, path, sys.exc_info())
  File "Z:\default\lib\shutil.py", line 270, in rmtree
    names = os.listdir(path)
WindowsError: [Error 3] The system cannot find the path specified:
'foo\\*.*'
>>> e = sys.last_value
>>> e.errno
2
>>> e.winerror
3
>>> errno.errorcode[2]
'ENOENT'

There was already a test for this, but it was complicated and had a
subtle bug (custom command objects need to be put in dist.command_obj so
that other command objects may see them) that rendered it moot.

Packaging uses the shutil.make_archive function copied from distutils,
which does not support compress.  There is no test to check that
“bdist --format whatever” works, so this slipped by.

These options were used to implement “setup.py --name”,
“setup.py --version”, etc. which are now handled by the pysetup metadata
action or direct parsing of the setup.cfg file.

As a side effect, the Distribution class no longer accepts a 'url' key
in its *attrs* argument: it has to be 'home-page' to be recognized as a
valid metadata field and passed down to the dist.metadata object.

I cleaned up some comments, docstrings and code along the way.

When called without option (“-f field” or “--all”), “pysetup metadata”
didn’t do anything useful.  Now it prints out all metadata fields.  The
“--all” option is removed.

the check against negative values, and add a note on this surprising test.
