Fix inconsistent behavior of the bytearray type: all its methods now allow
for items objects that can be converted to an integer using
operator.index().

Fix incorrect parsing of '020000000000.0', which produced a ValueError
instead of giving the correct float.

strings, respectively.

__hash__ is once again inherited by default. To allow collections.Hashable
to remain meaningful in the presence of the default hash implementation
(object.__hash__), it is now possible to explicit block inheritance of hash
by setting __hash__=None at the Python level, or
tp_hash=PyObject_HashNotImplemented at the C level.

Issue a RuntimeWarning instead of raising SystemError if the parent module
cannot be found while performing an absolute import. This means that an
incorrectly defined __package__ attribute will now only prevent relative
imports in that module rather than causing all imports from that module to
fail.

Minor change to slice.indices(): the start and stop arguments are now
treated identically, making the behaviour easier to describe and understand.
For example, slice(None, -10, 1).indices(9) now returns (0, 0, 1) instead of
(0, -1, 1), and slice(None, 10, -1).indices(10) returns (9, 9, -1) instead
of (9, 10, -1).

Calling a function with repeated keyword arguments, f(a=2, a=23), would not
cause a syntax error.  This was a regression from 2.4 caused by the switch

SimpleHTTPServer used to open text files in text mode. This is both
unnecessary (HTTP allows text content to be sent in several forms) and wrong
because the actual transmitted size could differ from the content-length.
The problem had been corrected in the 2.4 branch, but never merged into
trunk.
