Closes SF patch # 560250.

Bugfix candidate IMO.

Fix a bunch of multiline string constants that used +.

Call ensure_string() with one arg too, since the second value passed
was the default.

Make all returns explicit and rearrange logic to avoid extra
indentation.

mode is not computed in dry_run mode, so it can't be included in the
log message.

Fixes a bug for Solaris pkgtool (bdist_pkgtool) that would have
prevented it from building subpackages.

constant.

This is a conservative version of SF patch 504889.  It uses the log
module instead of calling print in various places, and it ignores the
verbose argument passed to many functions and set as an attribute on
some objects.  Instead, it uses the verbosity set on the logger via
the command line.

The log module is now preferred over announce() and warn() methods
that exist only for backwards compatibility.

XXX This checkin changes a lot of modules that have no test suite and
aren't exercised by the Python build process.  It will need
substantial testing.

While I was at it, I added a tp_clear handler and changed the
tp_dealloc handler to use the clear_slots helper for the tp_clear
handler.

Also tightened the rules for slot names: they must now be proper
identifiers (ignoring the dirty little fact that <ctype.h> is locale
sensitive).

Also set mp->flags = READONLY for the __weakref__ pseudo-slot.

Most of this is a 2.2 bugfix candidate; I'll apply it there myself.

 # XXX this isn't used anywhere, and worse, it has the same name as a method
 # in Command with subtly different semantics.  (This one just has one
 # source -> one dest; that one has many sources -> one dest.)  Nuke it?

Yes.  Nuke it.

Make Tkinter.TclError derive from Exception, it was a string.

modules, distutils does not understand that the build version of the
source tree is needed.

This patch fixes distutils.sysconfig to understand that the running
Python is part of the build tree and needs to use the appropriate
"shape" of the tree. This does not assume anything about the current
directory, so can be used to build 3rd-party modules using Python's
build tree as well.

This is useful since it allows us to use a non-installed debug-mode
Python with 3rd-party modules for testing. It as the side-effect that
set_python_build() is no longer needed (the hack which was added to
allow distutils to be used to build the "standard" extension modules).

This closes SF patch #547734.

BOM_UTF32, BOM_UTF32_LE and BOM_UTF32_BE that represent the Byte
Order Mark in UTF-8, UTF-16 and UTF-32 encodings for little and
big endian systems.

The old names BOM32_* and BOM64_* were off by a factor of 2.

This patch complies with the following request found
near the top of configure.in:

# This is for stuff that absolutely must end up in pyconfig.h.
# Please use pyport.h instead, if possible.

I tested this patch under Cygwin, Win32, and Red
Hat Linux. Python built and ran successfully on
each of these platforms.

__name__ and __doc__.

docstring for an uninitialized module object).

Change the module constructor (module_init) to have the signature
__init__(name:str, doc=None); this prevents the call from type_new()
to succeed.  While we're at it, prevent repeated calling of
module_init for the same module from leaking the dict, changing the
semantics so that __dict__ is only initialized if NULL.

Also adding a unittest, test_module.py.

This is an incompatibility with 2.2, if anybody was instantiating the
module class before, their argument list was probably empty; so this
can't be backported to 2.2.x.

unfortunate but unlikely case that PyType_Ready() fails.

Will fix in 2.2.x too.
