Package samba-pidl: Information

- Update to stable release of Samba 4.20
- Major changes from upstream:
  + The password access tool "samba-tool user getpassword" and the password sync
    tool "samba-tool user syncpasswords" allow attributes to be chosen for output.
  + samba-tool has been extended to provide client-side support for Group Managed
    Service accounts (reading the current and previous gMSA password and writing
    a Kerberos Ticket Granting Ticket (TGT) to a local credentials cache).
  + Windows Search Protocol (WSP) experimental command line client "wspsearch".
  + 'smbcacls' has been extended to allow DACLs to be saved and restored to/from
    a file (in interchangeable format with windows cmd line tool 'icacls.exe').
  + samba-tool now allows users to be associated with claims, the creation and
    management of authentication policies and silos.
  + AD DC support for Authentication Silos and Authentication Policies with
    (functional level must be set to 2012_R2 or later / 2016 latest supported).
  + Support of Conditional ACEs, Resource Attribute ACEs and the Security
    Descriptor Definition Language (SDDL) extensions for conditional ACEs and
    resource attribute ACEs.
  + The Workstation Service Remote Protocol [MS-WKST] calls NetWkstaGetInfo
    and NetWkstaEnumUsers) returns the list of locally logged on users, which
    getting the list from utmp, is not Y2038 safe and has been removed.

- Update to maintenance release of Samba 4.19
- Fixes from upstream (Samba#15580):
  + Packet marshalling push support missing for
     CTDB_CONTROL_TCP_CLIENT_DISCONNECTED and
     CTDB_CONTROL_TCP_CLIENT_PASSED.

- Add support 'client force dns canonicalize hostname' global parameter, enables
  client library tries to resolve canonical name. This feature allows to
  communicate via kerberos to services using CNAME records without adding SPNs.

  + If we fail to close file_handle ensure we should reset the fd (Samba#15527).
  + simplify handling of failing fstat() after unlinking file (Samba#15527).
