Simo Sorce a580c871d3 r19831: Big ldb_dn optimization and interfaces enhancement patch
This patch changes a lot of the code in ldb_dn.c, and also
removes and add a number of manipulation functions around.

The aim is to avoid validating a dn if not necessary as the
validation code is necessarily slow. This is mainly to speed up
internal operations where input is not user generated and so we
can assume the DNs need no validation. The code is designed to
keep the data as a string if possible.

The code is not yet 100% perfect, but pass all the tests so far.
A memleak is certainly present, I'll work on that next.

Simo.

This is the registry library. The registry is basically a bunch of
hives that can be loaded from different places.

The various registry backends provide support for loading/saving
specific types of hives:

 - ldb 
 - w95 (USER.DAT-style files)
 - nt4 (NTUSER.DAT-style files)
 - gconf (GNOME configuration)
 - rpc (Remote individual hives)

Instead of opening individual hives, one can also open a 'complete'
registry by using one of these three functions:
 
 - reg_open_local() - load local registry, see below
 - reg_open_remote() - connect to remote registry over RPC
 - reg_open_wine() (not working yet)

reg_open_local() loads a set of hives based on smb.conf settings.
Lines in smb.conf should have the following syntax:

registry:<hivename> = <backend>:<location>

So an example usage could be:

registry:HKEY_CURRENT_USER = nt4:NTUSER.DAT
registry:HKEY_LOCAL_MACHINE = ldb:tdb://registry.tdb

WERR_NOT_SUPPORTED will be returned for all hives that haven't been set.

On Windows the various registry hives are loaded from:

HKEY_CURRENT_CONFIG: %SystemRoot%\System32\Config\System
HKEY_CURRENT_USER: %Profile%\NTUser.dat
HKEY_LOCAL_MACHINE\SAM: %SystemRoot%\System32\Config\Sam
HKEY_LOCAL_MACHINE\Security: %SystemRoot%\System32\Config\Security
HKEY_LOCAL_MACHINE\Software: %SystemRoot%\System32\Config\Software
HKEY_LOCAL_MACHINE\System: %SystemRoot%\System32\Config\System
HKEY_USERS\.DEFAULT: %SystemRoot%\System32\Config\Default
HKEY_LOCAL_MACHINE\HARDWARE: is autogenerated
