tests:  Moved ExtensionSaver from test_copy_reg into pickletester, and
use it both places.  Once extension codes get assigned, it won't be
safe to overwrite them willy nilly in test suites, and ExtensionSaver
does a thorough job of undoing any possible damage.

Beefed up the EXT[124] tests a bit, to check the smallest and largest
codes in each opcode's range too.

Moved such EXT tests as currently exist from TempAbstractPickleTests to
AbstractPickleTests, so that test_cpickle runs them too.

but for testing too.

so we can jump to the error handling code that does.
(Spotted by Neal Norwitz)

blindly assumed that tp_as_sequence->sq_item always returns
a str or unicode object. This might fail with str or unicode
subclasses.

This patch checks whether the object returned from __getitem__
is a str/unicode object and raises a TypeError if not (and
the filter function returned true).

Furthermore the result for __getitem__ can be more than one
character long, so checks for enough memory have to be done.

continuing to call these "time tuples" is misleading at best.

this clarifies that they are part of an internal API (albeit shared
between pickle.py, copy_reg.py and cPickle.c).

I'd like to do the same for copy_reg.dispatch_table, but worry that it
might be used by existing code.  This risk doesn't exist for the
extension registry.

outcome as __slotnames__ on the class.  (Like __slots__, it's not safe
to ask for this as an attribute -- you must look for it in the
specific class's __dict__.  But it must be set using attribute
notation, because __dict__ is a read-only proxy.)
