Minor fix-ups to named tuples:
* Make the _replace() method respect subclassing.
* Using property() to make _fields read-only wasn't a good idea.
It caused len(Point._fields) to fail.
* Add note to _cast() about length checking and alternative with the star-operator.

Continue rolling back pep-3141 changes that changed behavior from 2.5. This
round included:
* Revert round to its 2.6 behavior (half away from 0).
* Because round, floor, and ceil always return float again, it's no
longer necessary to have them delegate to __xxx___, so I've ripped
that out of their implementations and the Real ABC. This also helps
in implementing types that work in both 2.6 and 3.0: you return int
from the __xxx__ methods, and let it get enabled by the version
upgrade.
* Make pow(-1, .5) raise a ValueError again.
