The problem here was that with the packet code set to serialise, we
can have multiple packets 'processing' at once, and previously the
second packet (allowed because we are spining on an event context down
the stack) would clear the flag.

events, and we don't want a SMB packet to be processed on this stream
until after the stream structure is fully setup

which allows a server ID to have an node number. The node number will
be zero in non-clustered case. This is the most basic hook needed for

contexts from the application layer into the socket layer.
This improves a number of correctness aspects, as we now allow LDAP
packets to cross multiple SASL packets. It should also make it much
easier to write async LDAP tests from windows clients, as they use SASL
by default. It is also vital to allowing OpenLDAP clients to use GSSAPI
against Samba4, as it negotiates a rather small SASL buffer size.
This patch mirrors the earlier work done to move TLS into the socket
layer.
Unusual in this pstch is the extra read callback argument I take. As
SASL is a layer on top of a socket, it is entirely possible for the
SASL layer to drain a socket dry, but for the caller not to have read
all the decrypted data. This would leave the system without an event
to restart the read (as the socket is dry).
As such, I re-invoke the read handler from a timed callback, which
should trigger on the next running of the event loop. I believe that
the TLS code does require a similar callback.
In trying to understand why this is required, imagine a SASL-encrypted
LDAP packet in the following formation:
+-----------------+---------------------+
| SASL Packet #1 | SASL Packet #2 |
----------------------------------------+
| LDAP Packet #1 | LDAP Packet #2 |
----------------------------------------+
In the old code, this was illegal, but it is perfectly standard
SASL-encrypted LDAP. Without the callback, we would read and process
the first LDAP packet, and the SASL code would have read the second SASL
packet (to decrypt enough data for the LDAP packet), and no data would
remain on the socket.
Without data on the socket, read events stop. That is why I add timed
events, until the SASL buffer is drained.
Another approach would be to add a hack to the event system, to have it
pretend there remained data to read off the network (but that is ugly).
In improving the code, to handle more real-world cases, I've been able
to remove almost all the special-cases in the testnonblock code. The
only special case is that we must use a deterministic partial packet
when calling send, rather than a random length. (1 + n/2). This is
needed because of the way the SASL and TLS code works, and the 'resend
on failure' requirements.

structure that is more generic than just 'IP/port'.
It now passes make test, and has been reviewed and updated by
metze. (Thankyou *very* much).
This passes 'make test' as well as kerberos use (not currently in the
testsuite).
The original purpose of this patch was to have Samba able to pass a
socket address stucture from the BSD layer into the kerberos routines
and back again. It also removes nbt_peer_addr, which was being used
for a similar purpose.
It is a large change, but worthwhile I feel.

management system I proposed on samba-technical a couple of days
ago. Essentially it is a very lightweight way for any code in Samba to
make IDL based rpc calls to anywhere else in the code, without the
client or server having to go to the trouble of setting up a full rpc
service.
It can be used with any of our existing IDL, but I expect it will
mostly be used for a new set of Samba specific management calls.
The LOCAL-IRPC torture test demonstrates how it can be used by calling
the echo_AddOne() call over this transport.

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)

the packets it receives, but it at least shows how the server
structure will work.
To implement it I extended the libcli/nbt/ library to allow for an
incoming packet handler to be registered. That allows the nbt client
library to be used for low level processing of the nbtd server packets.
Other changes:
- made the socket library always set SO_REUSEADDR when binding to an
interface, to ensure that restarts of a server don't have to wait
for a couple of minutes.
- made the nbt port configurable. Defaults to 137, but other ports
will be useful for testing.

themselves are run as a single process, but run as a child of the
main process when smbd is run in the standard model, and run as part
of the main process when in the single mode.
- rewrote the winbind template code to use the new task services. Also
fixed the packet queueing
- got rid of event_context_merge() as it is no longer needed
