  Backport PEP 3141 from the py3k branch to the trunk. This includes r50877 (just
  the complex_pow part), r56649, r56652, r56715, r57296, r57302, r57359, r57361,
  r57372, r57738, r57739, r58017, r58039, r58040, and r59390, and new
  documentation. The only significant difference is that round(x) returns a float
  to preserve backward-compatibility. See http://bugs.python.org/issue1689.

  Modified PyImport_Import and PyImport_ImportModule to always use absolute imports by calling __import__ with an explicit level of 0
