routines to return an NTSTATUS. This should help track down errors.
Use a bit of talloc_steal and talloc_unlink to get the real socket to
be a child of the GENSEC or TLS socket.
Always return a new socket, even for the 'pass-though' case.

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.

- the 0xffffffffffffffff seqnum is reserved for SMB2 Break (oplock breaks)
so don't use it in a request. we should someday try to test this...

security
descriptor. This is something that W2k3 does _not_ pass and probably is not
expected to, it seems the don't check access at tconX time.
Thanks to metze for the hint how in the srvsvc_NetShareInfo1501 struct the
length of the sd can be encoded in idl.
As metze says, there's probably more to the share secdesc, this needs more
testing. This one is here to walk the samba3 code.

is no padding...

there're 8 more unknown bytes...
Note:
- vista-CTP also support this as a server,
but uses the old format as client
- but vista-beta2 only uses and accept the new format

as we setup the 1 padding byte for non present dynamic part,
we need to overwrite it when we're getting a real dynamic part,
so we need to remove the buf->size +=1 when we do the first
push to the dynamic part (when buf->dynamic is still but->body + buf->body_fixed)

correct, or we try and do a memcmp on the trailing '\0'.
This happens because we now use memcmp for the prefix matching.
I just wish I had a test other than a particular invocation of the OSX
client. (I've tried and failed so far)
