The background queue process is repsonsible for that.
Just reload printers if necessary or wait for a message from bq to do that.

The cups backend forks a child to do asynchronous work.
We need a sigchld handler in bq to properly wait for the chilod to finish and
reap it, otherwise it hangs the forever as a zombie process.

Children were not properly receiving messages to reload printers when
the background queue process was dispatching them.

Children Ids must start at 1 as 0 represent the father.
Also fix callbacks that restart logs to use a procedd global variable that
holds the Id so that they work correctly both fot the parent process and the
children.

... until we are ready to handle it.
Also make us ready as early as possible in spoolssd.

This allows for setting up signal handlers earlier which is needed
for the following patch. It also simplify the code in a few places.
After all we never have more than pool active at any time during
spoolssd life span.

This way each child has its own log file and avoid mixing all logs form all
children in the same parent log file.

This way we are sure the cache is primed properly and messages can be sent to
processes if necessary as all messaging has been set up.

We need to properly handle preforked children so it is better to just do that
automatically.
If the parent needs/wants to intercept SIGCHLD events it can set a callback
that will be called by the prefork code once the internal cleanup function that
checks all prefork children has been executed.

This way the parent doesn't need to know how to handle dead children and
keeps all of that within the prefork abstraction.

example:
spoolssd:prefork = 10:100:5
will configure spoolssd to start with a minimum of 10 preforked children,
a max set to 100 children and spawns/retires 5 children at a time when
ramping up/scaling down.

This also allows to make each children serve more than one client at the same
time if necessary.

This should make it more scalable and able to handle easily multiple clients at
the same time.

This way we can properly deal with pcap updates in the background queue process
if it is enabled (on by default) and not perform these actions in the main
smbd process.

Also start new folder lib/dbwrap/ where dbwrap_open.c is stored and
make the fallbacke implementation functoins non-static and create a
dbwrap_private.h header file that contains their prototypes.

This patch finally has the same structure being used to describe the
authorization data of a user across the whole codebase.
This will allow of our session handling to be accomplished with common code.

This makes auth3_session_info identical to auth_session_info
The logic to convert the info3 to a struct auth_user_info is
essentially moved up the stack from the named pipe proxy in
source3/rpc_server to create_local_token().

This is closer to the layout of struct auth_session_info in auth.idl

This brings this structure one step closer to the struct auth_session_info.
A few SMB_ASSERT calls are added in some key places to ensure that
this pointer is initialised, to make tracing any bugs here easier in
future.
NOTE: Many of the users of this structure should be reviewed, as unix
and NT access checks are mixed in a way that should just be done using
the NT ACL. This patch has not changed this behaviour however.

This seperation between the structure used inside the auth modules and
in the wider codebase allows for a gradual migration from struct
auth_serversupplied_info -> struct auth_session_info (from auth.idl)
The idea here is that we keep a clear seperation between the structure
before and after the local groups, local user lookup and the session
key modifications have been processed, as the lack of this seperation
has caused issues in the past.
