s4:dsdb:acl_read: Implement "List Object" mode feature

s4:dsdb:acl_read: Implement "List Object" mode feature

See [MS-ADTS] 5.1.3.3.6 Checking Object Visibility

I tried to avoid any possible overhead for the common cases:

- SEC_ADS_LIST (List Children) is already granted by default
- fDoListObject is off by default

Overhead is only added if the administrator turned on
the fDoListObject feature and removed SEC_ADS_LIST (List Children)
from a parent object.
