scheme in situations that likely won't benefit from it.  This further
improves memory utilization from Py2.3 which always over-allocates
except for PyList_New().

Situations expected to benefit from over-allocation:
    list.insert(), list.pop(), list.append(), and list.extend()

Situations deemed unlikely to benefit:
    list_inplace_repeat, list_ass_slice, list_ass_subscript

The most gray area was for listextend_internal() which only runs
when the argument is a list or a tuple.  This could be viewed as
a one-time fixed length addition or it could be viewed as wrapping
a series of appends.  I left its over-allocation turned on but
could be convinced otherwise.

array.extend() now accepts iterable arguments implements as a series
of appends.  Besides being a user convenience and matching the behavior
for lists, this the saves memory and cycles that would be used to
create a temporary array object.

lists.  Speeds append() operations and reduces memory requirements
(because of more conservative overallocation).

Paves the way for the feature request for array.extend() to support
arbitrary iterable arguments.

Makes it more likely that all loop operations are in the cache
at the same time.

avoids creating an intermediate tuple for iterable arguments other than
lists or tuples.

In other words, a+=b no longer requires extra memory when b is not a
list or tuple.  The list and tuple cases are unchanged.

for xrange and list objects).

* list.__reversed__ now checks the length of the sequence object before
  calling PyList_GET_ITEM() because the mutable could have changed length.

* all three implementations are now tranparent with respect to length and
  maintain the invariant len(it) == len(list(it)) even when the underlying
  sequence mutates.

* __builtin__.reversed() now frees the underlying sequence as soon
  as the iterator is exhausted.

* the code paths were rearranged so that the most common paths
  do not require a jump.

was academic and it was potentially confusing to use.

* Replace sprintf message with a constant message string -- this error
  message ran on every invocation except straight deletions but it was
  only needed when the rhs was not iterable.  The message was also
  out-of-date and did not reflect that iterable arguments were allowed.

* For inner loops that do not make ref count adjustments, use memmove()
  for fast copying and better readability.

* For inner loops that do make ref count adjustments, speed them up by
  factoring out the constant structure reference and using vitem[] instead.

* Defer error handling for wrong number of arguments to the
  unpack_iterable() function.  Cuts the code size almost in half.

* Replace function calls to PyList_Size() and PyTuple_Size() with
  their smaller and faster macro counterparts.

* Move the constant structure references outside of the inner loops.

Side-effects were deemed unnecessary and were causing problems at shutdown
time when threads were catching exceptions at start time and then triggering
exceptions trying to call currentThread() after gc'ed.  Masked the initial
exception which was deemed bad.

The writelines() method now accepts any iterable argument and writes
the lines one at a time rather than using ''.join(lines) followed by
a single write.  Results in considerable memory savings and makes the
method suitable for use with generator expressions.
