r4096: move the samdb code to source/dsdb/

the idea is to have a directory service db layer
which will be used by the ldap server, samr server, drsuapi server
authentification...

I plan to make different implementations of this interface possible
- current default will be the current samdb code with sam.ldb
- a compat implementation for samba3 (if someone wants to write one)
- a new dsdb implementation which:
  - understands naming contexts (directory parrtitions)
  - do schema and acl checking checking
  - maintain objectGUID, timestamps and USN number,
    maybe linked attributes ('member' and 'memberOf' attributes)
  - store metadata on a attribute=value combination...
