This fixes upgrading from 4.7 and earlier releases, and makes the DB
reindexing more transparent. It should also make it easier to handle
future normalisation rule changes, e.g. if we change the pack-format
of integer indexes in a future release.
Without this change, the should have still handled reindexing the
database. We don't know why exactly this wasn't happening correctly,
but opening a transaction early in the samba process startup should
now guarantee that the DB is correctly reindexed by the time the main
samba code runs.
An alternative fix would have been to open a transaction in the the
DSDB module stack every time we connect to the database. However, this
would add an extra write lock every time we open the DB, whereas
starting samba happens much more infrequently.

This prevents a backup tar file, created with the new official
backup tools, from being extracted and replicated.
This is done here to ensure that samba-tool and ldbsearch can
still operate on the backup (eg for forensics) but starting
Samba as an AD DC will fail.

The standard model uses a pipe to signal the worker processes spawned on
accept that the controlling process has terminated and that they should
shut down. This pipe is currently a static global variable in
process_standard.c.
This patch replaces that global pipe with a file descriptor passed into
the process model init functions, giving a single mechanism across all process
models. This paves the way for the addition of a pre-fork process model.
Ensuring that the correct file descriptors are closed, is difficult so
it is best do this only once rather than require the process models to
do this individually.
Notes on debugging pipe ownership:
Add code to log the process id and the file descriptor of the writeable
pipe.
run:
lsof | grep FIFO | grep samba | grep <process id>
this will produce lines like:
samba 25624 him 4w FIFO 0,10 0t0 472206 pipe
where: 4w is the file descriptor and mode and the number to the left
of "pipe" is the pipe id.
then:
lsof | grep FIFO | grep samba | grep <pipe id>
This will display all the processes with the pipe open and the mode
only the smbd master process should have it open in write mode.

Ensure the messaging dgm context goes away *before* the tevent
context. The messaging dgm context will likely have active fd or timer
events, their rundown will touch the associated tevent context.
Otoh, I deliberately don't free the imessaging context here, that's going
to happen as part of freeing the talloc_autofree_context() as before. I
think it suffers the same problem, eg imessaging_deregister() works on
an imessaging_context that might already be freed. But as it works,
don't change it.

This removes quite a bit of code. All reasonable systems have /dev/urandom
these days. Linux, Solaris and the BSDs do. In case we find a system
without /dev/urandom, we will have to go hunting in other libraries.
The main reason for this is speed: On Ubuntu 14.04 doing direct reads from
/dev/urandom is 2-3 times faster than our md4 based code. On virtualized
FreeBSD 10 the difference is even larger.
My first approach was to use fopen/fread. It was even faster, but less
than twice as fast. So I thought we could save the additional complexity
when having to deal with throwing away buffers when forking and the
additional memory footprint per process.
With this simple generate_random_buffer it will be easier to adapt new
syscalls to get randomness.
