These references were triggering the ambiguous talloc_free errors from
the recent talloc changes when the server is run using the 'standard'
process model instead of the 'single' process model. I am aiming to
move the build farm to use the 'standard' process model soon, as part
of an effort to make our test environment better match the real
deployment of Samba4.
The references are not needed as the way that the event context is
used is as the 'top parent', so when the event context is freed then
all of the structures that were taking a reference to the event
context were actually freed as well, thus making the references
redundent.
Make sure we pass around the event_context where we need it instead.
All test but a few python ones fail. Jelmer promised to fix them.

If I remember it right and when I look at the git log, then this way to do the
async functions was designed by me.
(This used to be commit 8d44f997c88b97fc40a88eebd50b6df720c0c10f)
There are still a few tidyups of old FSF addresses to come (in both s3
and s4). More commits soon.

finished when we need to trigger the continuation immediately.
Via a fairly complex path, this fixes the problem where all hosts in
the build farm that do not have ipv6 failed a lot of the RPC
tests. This happened because the dcerpc_connect() async code used a
composite_continue() on a context which was already in an error state,
due to the socket backend saying that ipv6 was unavailable
(This used to be commit dbf935d38b6b1fea5ed00e94c9b1a518cb14768b)
the composite_context structue, we should try to convert all code
to use this because there're a lot of places where the we have
bugs with this task...
- add a composite_continue_smb2() helper
We should try to hide the internals of the composite code from the users
to avoid errors (and I found a lot of them... and will fix then step by step)

instead make the normal composite_done() and composite_error()
functions automatically trigger a delayed callback if the caller has
had no opportunity to setup a async callback
this removes one of the common mistakes in writing a composite function

Tridge, if you have the time, you might want to look at a problem I'm having
with unix domain stream sockets. From a comment in this commit:
/* Using composite_trigger_error here causes problems with the client
* socket. Linux 2.6.8 gives me a ECONNRESET on the next read after
* writing the reply when I don't wait the 100 milliseconds. */
This is in winbind/wb_cmd_userdomgroups.c:93.
The problem I have is that I can not *immediately* send an error reply to the
client because the next receive fails. Waiting 100 milliseconds helps. It
might also be a problem with epoll(), I don't really know.
I'd appreciate if you took a brief look at this, maybe I'm doing something
wrong.
Thanks,

* rename the composite helper functions from comp_* to composite_*
* Move the lsa initialization to wb_connect_lsa.c
* Equip smb_composite_connect with a fallback_to_anonymous
The latter two simplify wb_init_domain.c quite a bit.

Initialize a domain structure properly. Excerpt from wb_init_domain.c:
/*
* Initialize a domain:
*
* - With schannel credentials, try to open the SMB connection with the machine
* creds. Fall back to anonymous.
*
* - If we have schannel creds, do the auth2 and open the schannel'ed netlogon
* pipe.
*
* - Open LSA. If we have machine creds, try to open with ntlmssp. Fall back
* to schannel and then to anon bind.
*
* - With queryinfopolicy, verify that we're talking to the right domain
*
* A bit complex, but with all the combinations I think it's the best we can
* get. NT4, W2k3SP1 and W2k all have different combinations, but in the end we
* have a signed&sealed lsa connection on all of them.
*
* Is this overkill? In particular the authenticated SMB connection seems a
* bit overkill, given that we do schannel for netlogon and ntlmssp for
* lsa later on w2k3, the others don't do this anyway.

Thanks to Jeremy for his detective work, and to the Samba4 team for providing
such a great infrastructure.
Next step is to connect to SAM. Do it via LDAP if we can, fall back to samr
with all we have.

the events code replaces a destructor to one that returns allways -1
while it's calling the event handler
- we don't need the composite and winsrepl specific fixes any more
- this also fixes the problem with smbcli, dcerpc, cldap, ldap and nbt
request timeouts

stuff.
- don't use SMBCLI_REQUEST_* state's in the genreic composite stuff
- move monitor_fn to libnet.
NOTE: I have maybe found some bugs, in code that is dirrectly in DONE or ERROR
state in the _send() function. I haven't fixed this bugs in this
commit! We may need some composite_trigger_*() functions or so.
And maybe some other generic helper functions...

to cause an event to happen immediately. This allows metzes patch for
recognising IPs in resolve_name() to work, and also allows us to
remove some of the other code where we currently do specific checks
for is_ipaddress().
(This used to be commit 9cc000d868e1257ef6429f6f6f1f9d3c28ca330f)
make it possible to add optimisations to the events code such as
keeping the next timed event in a sorted list, and using epoll for
file descriptor events.
I also removed the loop events code, as it wasn't being used anywhere,
and changed timed events to always be one-shot (as adding a new timed
event in the event handler is so easy to do if needed)
(This used to be commit d7b4b6de51342a65bf46fce772d313f92f8d73d3)
rename the core structure to composite_context and the wait routine to
composite_wait() (suggestion from metze)
(This used to be commit cf11d05e35179c2c3e51c5ab370cd0a3fb15f24a)
have composite functions that are not made up of functions that
operate on smbcli_request structures.
(This used to be commit 4f6055b4fb7e287a29544ff1ca4e22f698efc478)
