16f96dbb5d CVE-2020-25718 s4-rpc_server: Provide wrapper samdb_confirm_rodc_allowed_to_repl_to()
This shares the lookup of the tokenGroups attribute.

There will be a new caller that does not want to do this step,
so this is a wrapper of samdb_confirm_rodc_allowed_to_repl_to_sid_list()
rather than part of it

4796b0a5c1 CVE-2020-25718 s4-rpc_server: Change sid list functions to operate on a array of struct dom_sid
This is instead of an array of struct dom_sid *.

The reason is that auth_user_info_dc has an array of struct dom_sid
(the user token) and for checking if an RODC should be allowed
to print a particular ticket, we want to reuse that a rather
then reconstruct it via tokenGroups.

This also avoids a lot of memory allocation.

232054c09b lib/util: remove extra safe_string.h file
lib/util/safe_string.h is similar to source3/include/safe_string.h, but
the former has fewer checks. It is missing bcopy, strcasecmp, and
strncasecmp.

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
they are used.

b8815dc23d lib/param: Create a seperate server role for "active directory domain controller"
This will allow us to detect from the smb.conf if this is a Samba4 AD
DC which will allow smarter handling of (for example) accidentially
starting smbd rather than samba.

To cope with upgrades from existing Samba4 installs, 'domain
controller' is a synonym of 'active directory domain controller' and
new parameters 'classic primary domain controller' and 'classic backup
domain controller' are added.

2ddf89a2bc Introduce system MIT krb5 build with --with-system-mitkrb5 option.
System MIT krb5 build also enabled by specifying --without-ad-dc

When --with-system-mitkrb5 (or --withou-ad-dc) option is passed to top level
configure in WAF build we are trying to detect and use system-wide MIT krb5
libraries. As result, Samba 4 DC functionality will be disabled due to the fact
that it is currently impossible to implement embedded KDC server with MIT krb5.

Thus, --with-system-mitkrb5/--without-ad-dc build will only produce
  * Samba 4 client libraries and their Python bindings
  * Samba 3 server (smbd, nmbd, winbindd from source3/)
  * Samba 3 client libraries

In addition, Samba 4 DC server-specific tests will not be compiled into smbtorture.
This in particular affects spoolss_win, spoolss_notify, and remote_pac rpc tests.
