local address
tstream_inet_tcp_connect_send() usually only gets no local port number
and it may use the wildcard address '0.0.0.0' or '::'.
tstream_inet_tcp_connect_recv() provides the used local address and port
which are used on the wire.

We got random double free errors, when getting events from
epoll_wait() and try to dereference the private talloc pointer
attached to it.
Before doing the close() in the tstream_disconnect_send() function
we need to delete the fd event.
commit 38f505530ba06323a56c7d3914630efffcd12629 only fixed it for
tdgram sockets.

the code used this pattent:
if (fd < 0) {
...various cleanups...
return fd;
}
it is much clearer to do this:
if (fd < 0) {
...various cleanups...
return -1;
}
as otherwise when reading the code you think this function may return
a fd.

This reverts commit 3d4fb698660381e650d7caeb5b7cff12847c0fb8.
This was wrong... The problem was in the caller, sa_len is a macro on irix

This reverts commit 63fc3978089df403d7e63462593784ff3d05e6e7.
We now don't support IPv6 when IPV6_V6ONLY isn't available,
as we rely on the behavior.

The previous code assumed the OS would happily accept sizeof(struct
sockaddr_storage). It seems some versions of Solaris do not like
this.

tsocket/bsd: fix bug #7115 FreeBSD includes the UDP header in FIONREAD
Metze, this has to have been wrong - you are throwing away the talloc_realloc
pointer returned. Also no error checking. Please review.
Thank goodness for gcc warnings :-).

Some system already have this as default. It's easier
to behave the same way on all systems and handle ipv6
and ipv4 sockets separate.

tstream_bsd_connect_send()
This is needed because, we can't use sizeof(sockaddr_storage) for AF_UNIX
sockets. Also some platforms require exact values for AF_INET and AF_INET6.

We want the explicit bind() when we don't use the any address.

This makes sure we fill the unspefic bytes with 0
and have zero termination for sockaddr_un.

This is needed as getpeername() truncates the length to 2 if the
peer socket has no name.

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.

tevent_add_fd does not properly set that. At least in epoll and select this is
the only error condition.
Metze, please check!

Remove two indentation levels by returning early on error.

We need to make sure that we free the sendto and recvfrom requests before
the tdgram_context
metze

sizeof(struct sockaddr_storage) generates EINVAL.

It will be replaced by tdgram_context and tstream_context.

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)

The idea is to have a tdgram and a tstream abstraction
which only provide tevent_req based io functions.

It seems that 'sun' is somewhere defined and we can
use it as name for variables or struct/union members.
