* Merge win_net.c and unix_net.c

+ Move win32/win_net.c to qcommon/net_ip.c and make it portable
  + Remove unix_net.c, but incorporate its revision history into win_net.c
  + Remove all IPX support -- this remains compatible with existing mods
  + This change also inadvertently gets us SOCKS support on non-Windows
    platforms
