857ed9ca5a tsocket/bsd: also ask for TEVENT_FD_READ when we want to write into a stream socket 
Otherwise we would not notice a broken connection.

b1d5e515b2 tsocket/bsd: more correctly check if the cached tevent_fd is still valid 
I some cases the pointer value of tevent_context is the same again,
if we do something like:

	ev1 = tevent_context_init();
	...
	fde = tevent_add_fd(ev1, fd, TEVENT_FD_READ...);
	...
	talloc_free(ev1);
	...
	ev2 = tevent_context_init();

	if (ev1 == ev2) {
		/* this can happen! */
	}

	if (tevent_fd_get_flags(fde) == 0) {
		/* this is always true */
	}

But the "talloc_free(ev1)" will set fde->event_ctx to NULL
and tevent_fd_get_flags() will always return 0.

ac65ae9b1d Set errno=ENOMEM if tevent_add_fd fails 
tevent_add_fd does not properly set that. At least in epoll and select this is
the only error condition.

Metze, please check!

c59ee5a139 tsocket: optimize tdgram_bsd a lot 
The desire is to do as less syscalls during the
tdgram_sendto_send/recv() and tdgram_recvfrom_send/recv()
operations.

1. we first try the sendto()/recvfrom() syscall and
   only use a fd event if we got EAGAIN.

2. we cache the fd event and only change it's flags
   if really needed.

For the highload case we do almost no epoll_ctl() and epoll_wait()/select()
syscalls anymore. This speeds up the LDAP-BENCH-CLDAP test
by more than 20%. (With a modified version of this test
which let the server skip any ldb calls and just return success
I'm getting about 8000 requests per second, while I'm getting
just about 6000 requests per second without optimization)

8d98070a9f tsocket: split out a smaller tdgram_context abstraction 
The idea is to have a tdgram and a tstream abstraction
which only provide tevent_req based io functions.
