s3:libsmb: fix smb signing for fragmented trans/trans2/nttrans requests

Before we send the secondary requests we need to remove the
old mid=>seqnum mapping and reset cli->mid and make the new
mid=>seqnum mapping "persistent".

The bug we had in cli_send_trans was this:
The first cli_send_smb() incremented cli->mid
and the secondary requests used the incremented mid,
but as cli->outbuf still had the correct mid,
we send the correct mid to the server. The real problem
was that the cli_send_smb() function stored the seqnum
under the wrong mid.

cli_send_nttrans() was totally broken and now follows the
same logic as cli_send_trans().

The good thing is that in practice the problem is unlikely to happen,
because max_xmit is large enough to avoid secondary requests.

s3-spoolss: fix notify_printer_status_byname.

This took me almost a week to find, so here a little longer explanation:

When a windows client registers printer *status* change notifies using
spoolss_RemoteFindFirstChangeNotify, it registers them to a print server handle,
not a printer handle. We were then correctly monitoring the printer status
changes but were sending out the spoolss_RouterReplyPrinterEx via the back-channel
connection with job_id set to 0 (which we only may do for monitored printer
change status notifies on printer handlers, not print server handles). Windows
was then showing a new empty dummy printer icon in the explorer as it cannot
route the notify event to the approriate local handle. It also discarded the
content of the notify event message of course. With this, printer change notify for
pausing, resuming and purging printers nicely works again here.

Jerry, Tim and all other printing gurus, please check.

s3: Fix a memleak in dbwrap_rbt.

The SMB_MALLOC'ed rbt node data was not free'd on talloc free of
the db context. This is a quick fix using talloc instead of malloc
for allocation of the node data.

Since malloc was originally used for performance reasons, one
might want to reverse to malloc and create a talloc destructor
that walks the tree and frees all the node data if this talloc
approach proves to be too slow..
