Add a post fork hook to the service API this will be called:
- standard process model
immediately after the task_init.
- single process model
immediately after the task_init
- prefork process model, inhibit_pre_fork = true
immediately after the task_init
- prefork process model, inhibit_pre_fork = false
after each service worker has forked. It is not run on the service
master process.
The post fork hook is not called in the standard model if a new process
is forked on a new connection. It is instead called immediately after
the task_init.
The task_init hook has been changed to return an error code. This ensures
the post_fork code is only run if the task_init code completed successfully.

dlz_bind9 has to count the number of times the plugin is 'created' by bind's
plugin manager so it doesn't repeat setup. Logging doesn't reflect this
reference counting logic properly and so messages like "samba_dlz: shutdown"
can, confusingly, come up when the database connection has not actually been
severed. This patch adds the necessary logging.

By using the new ldb_dn_add_child_val() we ensure that the user-controlled values are
not parsed as DN seperators.
Additionally, the casefold DN is obtained before the search to trigger
a full parse of the DN before being handled to the LDB search.
This is not normally required but is done here due to the nature
of the untrusted input.

This changes our DNS server to be much more careful when constructing DNS names
into LDB DN values.
This avoids a segfault deep in the LDB code if the ldb_dn_get_casefold() fails there.
A seperate patch will address that part of the issue, and a later patch
will re-work this code to use single API: ldb_dn_add_child_val(). This
is not squahed with this work because this patch does not rely on a new
LDB release, and so may be helpful for a backport.

Refactor the process model code to allow the addition of a prefork
process model.
- Add a process context to contain process model specific state
- Add a service details structure to allow service to indicate which
process model options they can support.
In the new code the services advertise the features they support to the
process model. The process model context is plumbed through to allow the
process model to keep track of the supported options, and any state
the process model may require.
