- note this is still uses the sync update() hook of the gensec modules
but it allows me to fix the callers first
Later auth_check_password() will also get an async version,
so that we can later implement an async version of auth_winbind
using async IRPC to the winbind task.

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.

In particular, this removes one use of the LDB_DN_NULL_FAILED macro,
which was being used on more than DNs, had an embedded goto, and
confused the IBM checker.
In the password_hash code, ensure that sambaAttr is not, before
checking the number of values.
In GENSEC, note that this switch value can't occour. This seems to be
the only way to quiet both the IBM checker and gcc, as well as cope
with possibly invalid inputs.

this isn't supported, fallback to NTLM.
Also, where we get a failure as 'logon failure', try and do a '3
tries' for the password, like we already do for CIFS. (Incomplete:
needs a mapping between RPC errors and the logon failure NTSTATUS).
Because we don't yet support Kerberos sign/seal to win2k3 SP1 for
DCE/RPC, disable this (causing SPNEGO to negotiate NTLM) when kerberos
isn't demanded.

This is used in the password prompt, and should be reversable by the

Also, don't look at the ccache, even for the guess code, if kerberos
