Get rid of webipc.h and DJBUNIX_FLAG_*

 Decent semantic header separation is hard. It's always
an ongoing process. Here socket.h always included webipc.h
for listen(), and webipc.h always included djbunix.h for
socket_internal() and socketpair_internal(). That's ugh.
Just move all the socket stuff into one socket header.
Of course, djbunix.h is still needed most of the time for
fd_close() and other operations on fds, but those are
generic anyway.

 Also, O_CLOEXEC exists everywhere now, so we can use it as well
as O_NONBLOCK instead of redefining the flags in djbunix.h.
