kcc: default to logging to DBGLVL_WARNING
If the "-d" debug level parameter is not supplied, default to DBGLVL_WARNING.
Overiding the "log level" set in smb.conf.
When samba runs the kcc command stderr output is logged at DBGLVL_ERR,
the default log destination is stderr. As a result any log messages
generated by the kcc command, are effectively logged at DBGLVL_ERR.
This causes issues if auth or audit logging are enabled in smb.conf.

repl_md: Avoid dropping cross-partition links
Cross-partition links could still be dropped if GET_TGT was already
previously set for the replication.
This was due to a slight error in the order of logic. We never want to
ignore cross-partition links (regardless of whether the TARGETS_UPTODATE
/GET_TGT flag is set). We should only be returning early in the
GET_TGT case if the objects are both in the same partition.
BUG: https://bugzilla.samba.org/show_bug.cgi?id=14022
RN: When the AD domain contained a linked attribute that spanned
partitions, DRS replication could drop the link. This dropped link could
then result in subtle differences in behaviour between DCs, as some DCs
would have the link and others wouldn't. When this issue occurred, the
dropped link would be logged in a warning message:
"<target-dn> is Unknown but up to date. Ignoring link from <source-dn>"
This issue would not always occur - it depended a lot on the database
contents. Typically, it would only potentially occur when joining a new
DC to the domain (doing an ldapcmp after the join would also highlight
the problem, if it occurred). This issue has now been resolved.

This adds a test-case to highlight a bug in the client side GetNCChanges

These tests mostly exercise the server-side behaviour of sending the
GetNCChanges, however, there's a bug in the client-side code when we try

the GET_TGT flag already having been set.
The test is exercising the client-side code by using the 'samba-tool drs
