Dan Winship 074df39681 Fix g_socket_get_available() with TCP on Windows 
Windows needs a special inefficient hack to implement
g_socket_get_available() correctly for UDP sockets, but that hack
isn't needed for TCP, and in fact, might give the wrong answer in that
case. Fix it to only use the hack with UDP.

Also, fix that case to handle non-blocking sockets as well.

And add a test case for g_socket_get_available() with TCP.
