[issue5914] Add PyOS_string_to_double function to C API

[Eric Smith]

Eric Smith <eric at trueblade.com> added the comment:

This looks okay to me (although since it's not hooked up I haven't
tested it). I particularly like that it doesn't allow leading
whitespace, and that the caller no longer has to remember errno
(forgetting to set and/or test it have both caused me problems in the past).

Does the whitespace change cause any problems for any internal code? I
wouldn't think so, but I haven't looked at it.

As long as you're at it, I'd suggest deprecating PyOS_ascii_*.
