classes have a __reduce__ that returns (self.__class__,
self.__getstate__()).  tzinfo.__reduce__() is a bit smarter, calling
__getinitargs__ and __getstate__ if they exist, and falling back to
__dict__ if it exists and isn't empty.

for this iconv() implementation in the init function.

For encoding: use a byteswapped version of the input if
neccessary.

For decoding: byteswap every piece returned by iconv()
if neccessary (but not those pieces returned from the
callback)

Comment out test_sane() in the test script, because
whether this works depends on whether byte swapping
is neccessary or not (an on Py_UNICODE_SIZE)

in 2.3.

_instantiate() method.

METH_NOARGS functions are still called with two arguments, one NULL,
so put that back into the function definitions (I didn't know this
until recently).

Make get_history_length() METH_NOARGS.

on the type instead of self.save(t).  This defeated the purpose of
NEWOBJ, because it didn't generate a BINGET opcode when t was already
memoized; but moreover, it would generate multiple BINPUT opcodes for
the same type!  pickletools.dis() doesn't like this.

How I found this?  I was playing with picklesize.py in the datetime
sandbox, and noticed that protocol 2 pickles for multiple objects were
in fact larger than protocol 1 pickles!  That was suspicious, so I
decided to disassemble one of the pickles.

This really needs a unit test, but I'm exhausted.  I'll be late for
work as it is. :-(

the same function, don't save the state or write a BUILD opcode.  This
is so that a type (e.g. datetime :-) can support protocol 2 using
__getnewargs__ while also supporting protocol 0 and 1 using
__getstate__.  (Without this, the state would be pickled twice with
protocol 2, unless __getstate__ is defined to return None, which
breaks protocol 0 and 1.)

Note this code is not used by the core on Win32, but in a block used only
by Windows CE.

popped a MARK, but without stack emulation the disassembler couldn't
know that, and subsequent indentation got hosed.

Now the disassembler does do enough stack emulation to catch this.  While
I was at it, also added lots of sanity checks for other stack operations,
and correct use of the memo.  This goes (I think) a long way toward being
a "pickle verifier" now too.

types.  The special handling for these can now be removed from save_newobj().
Add some testing for this.

Also add support for setting the 'fast' flag on the Python Pickler class,
which suppresses use of the memo.
