58e8db912d s4:libnet Allow 'net password change' to work on expired passwords
We need to pass down flags to the DCE/RPC layer to allow fallback to
anonymous connections, as we can't log in with an expired password.

The anonymous connection can then change the password with SAMR.

b135f4467f r12858: This moves the libnet_LookupPdc code to use a GetDC request to find
the remote server's name, or in the absence of a local nbt_server to
communicate with (or without root access), a node status request.

The result is that we are in a better position to use kerberos, as well
as to remove the 'password server' mandatory parameter for the samsync
and samdump commands.  (I need this to put these into SWAT).

The only problem I have is that I must create a messaging context, which
requires a server ID.  As a client process, I don't expect to get
messages, but it is currently required for replies, so I generate a
random() number.  We probably need the servers to accept connections on
streamed sockets too, for client-only tasks that want IRPC.

Because I wanted to test this code, I have put the NET-API-* tests into
our test scripts, to ensure they pass and keep passing.  They are good
frontends onto the libnet system, and I see no reason not to test them.

In doing so the NET-API-RPCCONNECT test was simplified to take a
binding string on the command line, removing duplicate code, and
testing the combinations in the scripts instead.

(I have done a bit of work on the list shares code in libnet_share.c
to make it pass 'make test')

In the future, I would like to extend the libcli/findds.c code (based
off volker's winbind/wb_async_helpers.c, which is why it shows up a bit
odd in the patch) to handle getting multiple name replies, sending a
getdc request to each in turn.

(posted to samba-technical for review, and I'll happily update with
any comments)

acd6a086b3 r12510: Change the DCE/RPC interfaces to take a pointer to a
dcerpc_interface_table struct rather then a tuple of interface
name, UUID and version.

This removes the requirement for having a global list of DCE/RPC interfaces,
except for these parts of the code that use that list explicitly
(ndrdump and the scanner torture test).

This should also allow us to remove the hack that put the authservice parameter
in the dcerpc_binding struct as it can now be read directly from
dcerpc_interface_table.

I will now modify some of these functions to take a dcerpc_syntax_id
structure rather then a full dcerpc_interface_table.
