The core dcerpc server is required here, which also implies
DCERPC_COMMON.
This is required to move common/reply.c dcesrv_auth.c from
DCERPC_COMMON to dcerpc_server in the next commit.

"zone.com." and "zone.com" should be treated as the same zone. This patch
picks the unqualified representation as standard and enforces it, in order to
match BIND9 behaviour.
Note: This fixes the failing test added previously, but that test still fails
on the rodc test target so we modify the expected failure but don't remove it.

Move the calls to GUID_buf_string and dom_sid_str_buf into the
coresponding DBG_WARNING call, instead of using an intermediate variable.
While this violates the coding guidelines, doing this makes the code less
cluttred and means the functions are only called if the debug message is
printed.

Add a cache of GUID's that matched the last samr_EnunDomainUsers made on a
domain handle. The cache is cleared if resume_handle is zero, and when the
final results are returned to the caller.
The existing code repeated the database query for each chunk requested.

Add a cache of GUID's that matched the last samr_QueryDisplayInfo made on a
domain handle. The cache is cleared if the requested start index is
zero, or if the level does not match that in the cache.
The cache is maintained in the guid_caches array of the dcesrv_handle.
Note: that currently this cache exists for the lifetime of the RPC
handle.

Allow the rpc_server to run in the prefork process model. Due to the use
of shared handles and resources all of the rpc end points are serviced
in the first worker process. Those end points that can be run in
multiple processes (currently only Netlogon and management) are serviced in
the first and any subsequent workers.

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.

The logic for constructing the values for our own primary domain differs
from the values of trusted domains. In order to make the code easier to
understand we have a new fill_our_one_domain_info() helper that
only takes care of our primary domain.
The cleanup for the trust case will follow in a separate commit.

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.
