We can directly use smb_raw_open() to open a handle to a named pipe.
This avoids the need for the layer violation functions
dcerpc_smb_tree() and dcerpc_smb_fnum().

We now use smbXcli_conn_is_connected() and
dcerpc_binding_handle_is_connected() to verify only the dcerpc layer
got an error. The expected error is EIO mapped to NT_STATUS_IO_DEVICE_ERROR.
NT_STATUS_INVALID_HANDLE should only be visible at the SMB layer,
but we keep this as allowed return value for now, until
the dcerpc layer is fixed.

No clue what this does. In open_directory, "dir_existed" is not used after
open_mode_check. In open_file_ntcreate it's used, but I can't think of a case
right now where we would find a formerly nonexisting file to exist suddenly.

This makes grant_fsp_oplock_type independent from the values computed
in validate_oplock_types. It *might* make oplock calculation a bit
slower for heavily shared files, as we are walking the share mode array
twice. But we are doing so much stuff in open that I doubt the difference
is measurable. It clears up the code for me however, and I think that's
worth it.

This removes two variables in open_file_ntcreate based on the observation
that for exclusive and batch oplocks there can only be one entry. So
in these cases we don't need to keep pointers from find_oplock_types to
delay_for_oplocks. We can just reference the only share mode entry around.

This implements an idea by metze: Right now Samba does not grant level2
oplocks where it should: After an initial no-oplock open that has been
written to, we don't have the FAKE_LEVEL2_OPLOCK entry in locking.tdb
around anymore, this downgraded to NO_OPLOCK. Windows in this case will
grant level2 if being asked, we don't. Part of the reason for this
is that we don't have a proper mechanism to communicate the fact that
level2 needs to be broken to other smbds. Metze's insight was that we
have to look into brlock.tdb for every write anyway, so this might be
the right place to store this information.
My first reaction was that this is really hackish, but on further thought
this is not. oplocks depend on brlocks anyway, and we have the proper
mechanisms in place for brlocks.
The format for this change is to add one byte to the end of the brlock.tdb
record with value 1 if we have level2 oplocks around. Thus this patch
effectively reverts 8f41142 which I discovered while writing this
change. We now legally have unaligned records.
We can certainly talk about the format, but I'm not yet convinced we
need an idl for this yet. This is a potentially very hot code path,
and ndr marshalling has a cost.

This uses the documeted "winbindd socket directory" parameter instead.
This came about due to the merge of the two smb.conf tables in s3 and
s4 for the Samba 4.0 release. The s4 code used a real parameter,
which caused this to be documented, whereas no automatic procedure
existed to notice the parametric option and the need to document that.
The fact that this was not used consistently in both codebases is one
of the many areas of technical debt we still need to pay off here.

In handling RemoteFindFirstPrinterChangeNotifyEx requests, the spoolss
server can establish a "backchannel" connection to the print client, as
a mechanism for sending print notifications. This behaviour is governed
by the "print notify backchannel" smb.conf parameter.
This change sets "print notify backchannel" to "no" by default, which
sees Samba respond to RemoteFindFirstPrinterChangeNotifyEx requests with
WERR_SERVER_UNAVAILABLE. In recieving such a response, print clients can
fall back to polling for print queue changes.
