Fix test failure on Windows

Browse source 
The send{,to,msg} and recv{,from,msg} functions have been updated to
delegate to WriteFile and ReadFile when appropriate, due to the fact
that socketpair(AF_UNIX) is implemented using kFdFile.

Thanks @fabriziobertocci for writing the test that caught this.

See #148 and #122
