Now that we always require a 64 bit off_t, we no longer need SMB_OFF_T.

The performance of these is minimal (these days) and they can return
invalid results when used as part of applications that do not use
sys_fork().

We now only close fds 0, 1, 2 when we are a forked daemon, and take
care not to close a file descriptor that we might need for foreground
stdin monitoring.
This should fix stdout logging in the lsa and epmapper deamons (ie in
make test).

The printer list database format was recently changed to accommodate for
the printcap location field.
One of the tdb_pack calls is not provided with a location string
argument, this causes a crash on some platforms.

Driver file paths stored in the registry do not include the server path
prefix. delete_driver_files() incorrectly assumes such a prefix.

This will be used to enforce a lock hierarchy between the databases. We have
seen deadlocks between locking.tdb, brlock.tdb, serverid.tdb and notify*.tdb.
These should be fixed by refusing a dbwrap_fetch_locked that does not follow a
defined lock hierarchy.
Don't fail if the form already exists (or is builtin now).

load_printers() removes stale printers and we should only remove them if
we have a CUPS connection and talked to cups. Else we will remove every
configured printer if cups is not available.

If we *really* are a bout to exit (PF_WORKER_EXITING) then the event will not
be called as the loop will exit. Otherwise PF_SRV_MSG_EXIT may not be honoured
for a long time if we have cients connected, therefore keep handling SIGHUP
properly in those cases.

Also stop using the listening as now the prefork code properly sets
the PF_WORKER_ACCEPTING flag and it can be relied upon without having to keep
additional status around.

We can't have a clear idea of wether the worker is IDLE or BUSY.
The only things we can tell is if it is Alive, whether it is currently
Accepting connections or wether it is Exiting soon.
Remove PF_WORKER_IDLE, PF_WORKER_BUSY and replace their use with
PF_WORKER_ALIVE. Also properly assign PF_WORKER_ACCEPTING so that
users of the API can rely on the flag.

We used a lock mimicking what apache does for preforked children.
But it doesn't work properly in our case because we do not stop once a request
has been served. Clients are allowed to perform multiple requests and keep the
connection open.
This means that if we allow multiple clients per children, then a child could
take the lock and then be asked to do a long or even locking operation by a
client it already is serving. This woulkd cause the whole server to deadlock,
as the child is now busy and also holding on the lock.
Using a race on accept() by having a tevent_fd on the listening socket wait
for read events we never deadlock. At most we cause a bit of contention among
children. But in the generic case connections are much less frequent for us as
clients tend to be long lived. So the little contention we may have is not a
big deal.

We were not properly managing allowed clients and pool management was
duplicated across a few callers.
Concentrate all management heuristics in one single function.

Be more correct in load printers at startup.
If async process have already started we do not need to force a reload, but we
just need to load the printers. If other process have not finished initializing
it makes no sense to try to force them as they are masking SIGHUP unitl init is
done anyway.

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.

This allows for setting up signal handlers earlier which is needed
for the following patch. It also simplify the code in a few places.
