fixup_slot_dispatchers(): fix indentation.

- replace some log_error() calls with log_message()

- flush self.rfile before forking too (hope this works on Windows)

Add --install-scripts=$(BINDIR) argument to "setup.py install"

Made the presence/absence of a semicolon after macros consistent.

removed the tricks).

Changed the ENTER/LEAVE_ZLIB macros so as not to create a new block (a
new block is neither necessary nor helpful).

    Apparently this patch (rev 2.41) replaced all the good old "s#"
    formats in PyArg_ParseTuple() with "S".  Then it did
    PyString_FromStringAndSize() to get back the values setup by the
    "s#" format.  It also incref'd and decref'd the string obtained by
    "S" even though the argument tuple had a reference to it.

Replace PyString_AsString() calls with PyString_AS_STRING().

    A good rule of thumb -- if you never check the return value of
    PyString_AsString() to see if it's NULL, you ought to be using the
    macro <wink>.

Many functions used a local variable called return_error, which was
initialized to zero.  If an error occurred, it was set to true.  Most
of the code paths checked were only executed if return_error was
false.  goto is clearer.

The code also seemed to be written under the curious assumption that
calling Py_DECREF() on a local variable would assign the variable to
NULL.  As a result, more of the error-exit code paths returned an
object that had a reference count of zero instead of just returning
NULL.  Fixed the code to explicitly assign NULL after the DECREF.

A bit more reformatting, but not much.

XXX Need a much better test suite for zlib, since it the current tests
don't exercise any of this broken code.

TeX-ified its docstring.

It sets a ZlibError exception, using the msg from the z_stream pointer
if one is available.

passed to _beginthread().

masks any exception, not just AttributeError.  Fix this.

When PyString_FromStringAndSize() and _PyString_Resize() fail, they
set an exception.  There's no need to set a new exception.

Consistently indent 4 spaces.
Use whitespace around operators.
Put braces in the right places.

This changes Pythread_start_thread() to return the thread ID, or -1
for an error.  (It's technically an incompatible API change, but I
doubt anyone calls it.)

Add an optional argument to a decompression object's decompress()
method.  The argument specifies the maximum length of the return
value.  If the uncompressed data exceeds this length, the excess data
is stored as the unconsumed_tail attribute.  (Not to be confused with
unused_data, which is a separate issue.)

Difference from SF patch: Default value for unconsumed_tail is ""
rather than None.  It's simpler if the attribute is always a string.

suggested in SF patch #424475.  Also document exception return.

object.c, PyObject_Str:  Don't try to optimize anything except exact
string objects here; in particular, let str subclasses go thru tp_str,
same as non-str objects.  This allows overrides of tp_str to take
effect.

stringobject.c:
+ string_print (str's tp_print):  If the argument isn't an exact string
  object, get one from PyObject_Str.

+ string_str (str's tp_str):  Make a genuine-string copy of the object if
  it's of a proper str subclass type.  str() applied to a str subclass
  that doesn't override __str__ ends up here.

test_descr.py:  New str_of_str_subclass() test.

    When an extension imports another extension in its
    initXXX() function, the variable _Py_PackageContext is
    prematurely reset to NULL. If the outer extension then
    calls Py_InitModule(), the extension is installed in
    sys.modules without its package name. The
    manifestation of this bug is a "SystemError:
    _PyImport_FixupExtension: module <package>.<extension>
    not loaded".

    To fix this, importdl.c just needs to retain the old
    value of _Py_PackageContext and restore it after the
    initXXX() method is called. The attached patch does this.

    This patch applies to Python 2.1.1 and the current CVS.

size(), parse150(): try int() first, catch OverflowError, fall back to
long().

efficient:

- recurse down subclasses only once rather than for each affected
  slot;

- short-circuit recursing down subclasses when a subclass has its own
  definition of the name that caused the update_slot() calls in the
  first place;

- inline collect_ptrs().
