c2fcd83ed7 s4:libnet:py_net - free event context in dealloc fn
Creation of a new Net() object initializes an event context under
a NULL talloc context and then creates a new talloc context as a
child of the event context. The deallocation function for the
net object only frees the child and not the parent. This leaks an
fd for the tevent context and associated memory.

3e27dc4847 daemons: report status to systemd even when running in foreground
When systemd launches samba services, the configuration we have in
systemd service files expects that the main process (/usr/sbin/*)
would use sd_notify() to report back its status. However, we only use
sd_notify() when running become_daemon().

As a result, samba/smbd/winbindd/nmbd processes never report back its
status and the status updates from other childs (smbd, winbindd, etc)
are not accepted as we now have implied NotifyAccess=main since commit
d1740fb3d5a72cb49e30b330bb0b01e7ef3e09cc

This leads to a timeout and killing samba process by systemd. Situation
is reproducible in Fedora 33, for example.

Make sure that we have required status updates for all daemons in case
we aren't runnning in interactive mode.

183d5d63f4 DNS Resolver: support both dnspython before and after 2.0.0
`dnspython` 2.0.0 has many changes and several deprecations like:

```
> dns.resolver.resolve() has been added, allowing control of whether
search lists are used. dns.resolver.query() is retained for backwards
compatibility, but deprecated. The default for search list behavior can
be set at in the resolver object with the use_search_by_default
parameter. The default is False.

> dns.resolver.resolve_address() has been added, allowing easy
address-to-name lookups.
```

The new class `DNSResolver`:
- provides the compatibility layer
- defaults the previous behavior (the search list configured in the
  system's resolver configuration is used for relative names)
- defaults lifetime to 15sec (determines the number of seconds
  to spend trying to get an answer to the question)

The compatibility shim was developed by Stanislav Levin for FreeIPA and
adopted for Samba by Alexander Bokovoy.

7223f6453b 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.

This tests a sorts of combinations in order to
demonstrate the visibility of objects depending on:

- with or without fDoListObject
- with or without explicit DENY ACEs
- A hierachy of objects with 4 levels from the base dn
- SEC_ADS_LIST (List Children)
- SEC_ADS_LIST_LIST_OBJECT (List Object)
- SEC_ADS_READ_PROP
- all possible scopes and basedns

This demonstrates that NO_SUCH_OBJECT doesn't depend purely
on the visibility of the base dn, it's still possible to
get children returned und an invisible base dn.

It also demonstrates the additional behavior with "List Object" mode.

https://gitlab.com/samba-team/samba/-/merge_requests/1507 broke build on
Fedora 33 with GCC 10.2.1 for those compilation units that use

The reason for that is that ldb_attr_cmp() defined as

   #define ldb_attr_cmp(a, b) strcasecmp(a, b)

because attribute names restricted to be ASCII by RFC2251 (LDAPv3 spec).

A solution is to add
