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.

If this child has no clients, let the lock functions block for 1 second,
and then immediately reschedule the operation. This means we catch the lock
as soon as possible on a free child.
If, instead, we are already serving a client, we want to be non blocking,
so we timeout immediately on getting the lock, and then we sleep a 1/10th of
a second.
This means that a busy child will be slightly slower on picking up the lock,
but we won't block the existing client from communicating with us as we
immediately react to activity on the already opened file handler.

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

This will allow to hook the prefork socket handlers to the rpc service.

The allowed_clients var is a parent managed variable that tell children how
many clients they are allowed to handle at the same time. This way children
can overcommit but within parent controlled limits.

Primarily built for forked off rpc service daemons, but not tied to rpc

The max_data parameter of trans2/nttrans calls are not bound
to cli->max_xmit. Even with cli->max_xmit, which means the max
size of the whole SMB pdu, we would get fragmented trans2/nttrans
replies. That's why we can also use our maximum, which is CLI_BUFFER_SIZE.

We need for named pipes we need to send each fragment on its own to be a

Ignore fd events without EVENT_FD_READ or EVENT_FD_WRITE also in
run_events_poll(). They are ignore when building the array
for the syscall in event_add_to_poll_args(), so we need to
ignore them run_events_poll() too.

(bug #8357)
Currently we skip, the "gone async" interim response on read and write,
this caused the aio code path to grant 0 credits to the client
in the read/write responses.
