don't assign None to any attributes of the Extension object.

Add some test cases.

file.writelines() now tries to emulate the behaviour of file.write()
as closely as possible. Due to the problems with releasing the
interpreter lock the solution isn't exactly optimal, but still better
than not supporting the file.write() semantics at all.

to be extended somewhat -- right now it only tests the .writelines()
method.

How-to document for using Python for CGI scripting. Not complete and untested, but I'm checking it in so it won't get lost.

GetDialogWindow() returns an existing window.
Added a comment that the methodchain Dialogs->Windows is suspect under Carbon/MacOSX, but we need it under Carbon. No solution yet:-(

Window objects now also have an AutoDispose funcpointer (set for our windows, cleared for foreign windows). Needed mainly for Carbon (where we don't know about the windows belonging to our dialogs).
Fixed a few calls that return an ExistingWindow.

- Renamed socket to _socket.

Don't use our own malloc any more. It made test_longexp crash due to its optimization to lock blocks into a specific size malloc requests. This loses 15% performance, but that we'll have to live with:-(

Cheaper implementation of PyOS_CheckStack: only call StackSpace once and keep a sentinel in a static variable.

useless.  So the test of the dcgettext() function is removed.

useless.  So the category argument on _find() is removed, as is the
dcgettext() function.

cvs tree.  It creates the directory and gettext.mo file on the fly,
from the base64 encode binary data.

some changes.

                Added prototype to remove yet another warning.

Make a number of the handlers and helpers "static" since they are not
used in other C source files.  This also reduces the number of warnings.

Make a lot of the code "more Python".  (Need to get the style guide done!)

Minor cleanups.

Don't people *test* their changes?

much more explicit.  Also document that we're moving to Tcl/Tk 8.3.2.
Simplify .dsp files by getting rid of useless include paths.
.wse file changed to reflect that my setup is different than Guido's:
if you *build* a Python distro using python20.wse, beware!

(This fix is a bit broken, just as the test already was: the test for
testlist and listmaker are done always, whereas the test for exprlist and
the actual abort() are only done if Py_DEBUG is defined. Suggestions
welcome, I guess ;)
