5d8e794551 waf: Allow building with MIT KRB5 >= 1.20
gssrpc/xdr.h:105:1: error: function declaration isn’t a prototype
[-Werror=strict-prototypes]
  105 | typedef bool_t (*xdrproc_t)();
      | ^~~~~~~

This can't be fixed, as the protoype is variadic. It can take up to three
arguments.

7e6b818fea ktutil: Print the numeric enctype if krb5_enctype_to_string() fails
Sadly krb5_enctype_to_string() fails when des-cbc-crc encyrption

falling back to anything useful.

So fall back to printing 3 in the absense of anything more

in the smb_krb5_enctype_to_string() wrapper.

Add the missing elements to lib/util/safe_string.h remove the other
safe_string.h which is in the source3-specific path. To accomodate
existing uses of str(n?)casecmp, add #undef lines to source files where

Fold the two 32 bit values logon_id_high and logon_id_low into a single
64 bit logon_id in netr_identity_info.  This will be used to tie
together winbind and SamLogon requests in audit logging.

Summary of the of the Query and Response from Microsoft on it's usage.

[REG:119013019612095] [MS-NRPC]: NETLOGON_LOGON_IDENTITY_INFO: Does
the Reserved field have LogonId meaning?

Questions:
  In NetrLogonSamLogonEx does the Reserved field
  (of NETLOGON_LOGON_IDENTITY_INFO) have LogonId meaning?

  What is a valid LogonID, and does have any audit usage?

  Samba is sending a constant "deadbeef" in hex and would like to
  understand any usage of this field.

Response:
  The NRPC spec is accurate in defining the field as Reserved, and without
  protocol significance. In the header file in our source code, it is
  defined as LogonId and commented as such, but it’s effectively not used.
  This is probably why the API structure has that field name. It may have
  been intended as such but it’s not used.

Samba will send a random value in this field.

The post fork hook is not called in the standard model if a new process
