6cca5c8459 bpo-30592: Fixed error messages for some builtins. (#1996)
Error messages when pass keyword arguments to some builtins that
don't support keyword arguments contained double parenthesis: "()()".
The regression was introduced by bpo-30534.

bf623ae884 bpo-30061: Check if PyObject_Size()/PySequence_Size()/PyMapping_Size() (#1096)
raised an error.

Replace them with using concrete types API that never fails if appropriate.

5cd87a8d61 Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing.
Decreased density gives better collision statistics (average of 2.5 probes in a
full table versus 3.0 previously) and fewer occurences of starting a second
possibly overlapping sequence of 10 linear probes.  Makes resizes a little more
frequent but each with less work (fewer insertions and fewer collisions).

e1af6964b4 Remove unnecessary variables.
* so->used never gets changed during a resize
* so->filled only changes when dummies are present and being eliminated

ab479c49d3 Issue #26494: Fixed crash on iterating exhausting iterators.
Affected classes are generic sequence iterators, iterators of str, bytes,
bytearray, list, tuple, set, frozenset, dict, OrderedDict, corresponding
views and os.scandir() iterator.

2c257ab0f8 Responsibility for argument checking belongs in set.__init__() rather than set.__new__().
See dict.__new__() and list.__new__() for comparison.  Neither of those examine or touch
args or kwds.  That work is done in the __init__() methods.

a9406e77fa Issue #25421: __sizeof__ methods of builtin types now use dynamic basic size.
This allows sys.getsize() to work correctly with their subclasses with
__slots__ defined.
