Here's the socketmodule patch. I aggressively imported text from the docs for the docstrings, along with matching parameter names, given how far the old docstrings have drifted over time. The Windows-specific code is untested, but otherwise the tests pass. I tagged functions which can't be converted or whose argument handling is esoteric. These comments can be removed prior to commit.

I am not sure if one should convert a C-level class's init method.
