This patch moves further includes (the network part and lib.h) in common/. It is the last part to get the netbsd libc to compile under minix. Further moves will be needed as we get the netbsd libc to compile minix itself. Also, this patch add #ifndef's to termios.h, as it create problems with netbsd's namespace.h.
