SF Bug 676398 Doesn't handle non-built-in exceptions
1. Move exception formatting to the subprocess; allows subclassing of
   exceptions, including subclasses created in the shell without
   introducing excessive complexity in the RPC mechanism.
2. Provide access to linecache from subprocess to support this.

is just as easy.

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)

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.)

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.

Add some testing for this.

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