Receiving a MSG_PRINTER_DRVUPGRADE causes
smbd to iterate over all printers looking
for ones that uses the driver. This is a very
expensive operation requiring a read of all
registry printer parameters.
On a system with a large number of printers,
this causes the clients to timeout (smbd
can take longer than 60 seconds to respond).
This patch fixes the problem by forwarding
the MSG_PRINTER_DRVUPGRADE to the background
lpq queue updater process and allowing it to
take care of the updating of the changeid
in the registry, allowing the smbd connected
to the client to return to processing requests
immediately.

The <tmp> variable is tested at the end of the function to determine the
return value, but <tmp> is never initialized and there are conditions
under which it may be tested before a value is set.
This patch initializes <tmp> to NULL, which means that WERR_NOMEM will
be returned if the registry lookups fail.

This is a hack, but it should fix the bug:
change_notify_add_request() talloc moves smb_request away,
which is not expected by the smb2_notify.c code...
smbd_smb2_notify_reply() uses tevent_req_defer_callback()
(in older versions an immediate event) to defer the response.
This is needed as change_notify_reply() will do more things
after calling reply_fn() (smbd_smb2_notify_reply is this case)
and often change_notify_remove_request() is called after
change_notify_reply().
change_notify_remove_request() implicitly free's the smb_request
that was passed to change_notify_add_request().
smbd_smb2_fake_smb_request() added the smb_request as smb2req->smb1req,
which is expected to be available after smbd_smb2_notify_recv() returned.
The long term solution would be the following interface:
struct tevent_req *change_notify_request_send(TALLOC_CTX *mem_ctx,
struct tevent_context *ev,
struct files_struct *fsp,
uint32_t max_length,
uint32_t filter,
bool recursive);
NTSTATUS change_notify_request_recv(struct tevent_req *req,
TALLOC_CTX *mem_ctx,
DATA_BLOB *buffer);

This removes the ability to set paths like the sbindir, bindir, and changes the tool for setting lockdir
statedir etc to be via --option="lock dir=/var/lock".
These were originally added by commit 90a6873b05

The important use case, qemu, does not use these options, but specifies these directories via an smb.conf.
They are being removed to remove a layer from the loadparm system, now that options
can be specified from the command line. It will also make it easier to generate the affected
parameters from the XML documentation if this layer of indirection is removed.

This parameter is renamed because it does not normally return the current smb.conf file, but
instead returns the next one, as found in a config file = directive, to be loaded.
This avoids a conflict with the lpcfg_configfile from lib/param, which does refer to the
current smb.conf path.

The build system gives these two parameters different defaults
(compared with lock dir) in both the --enable-fhs and default mode, so
the logic to use lock dir no longer applies unless the build has been
very specially constructed.
Therefore, remove the special case handling and make these normal
parameters again.

Allow dirsort to work when multiple simultaneous
directories are open. The old code only keeps one
active private data pointer on the connection struct, opening
a second directory on the same connection will overwrite it.
This modification turns the private data pointer
into a linked list of open directories on the
connection struct, and finds the correct one by searching
on the passed in DIR *.
With this code in place, smbd passes raw.search
torture test on a share definition with:
