Phobos sockets

[Martin Hess]

I'm trying to figure which socket API to use in Phobos. There appears 
to be 3 choices for linux:

1) A general version: std.socket

2) A linux version: std.c.linux.socket
	- this one gets a version assert on X86_64

3) The last isn't really a socket class but it has the socket calls: 
std.c.unix.unix. It is used by version #1 above.

Version #2 redeclares the c socket api that is declared in #3

Are all 3 versions considered public?

Is #2 really just for X86, or should it also work with any Unix/BSD 
socket implementation?

Which one is best tested? Which of course leads to the question is 
there any kind of test suite for Phobos?
