CVE-2018-14629 dns: fix CNAME loop prevention using counter regression
The loop prevention should only be done for CNAME records!
Otherwise we truncate the answer records for A, AAAA or

vfs_fruit: avoid dereferencing fsp->base_fsp in fruit_fstat_meta_stream()
This helps avoiding a NULL dereference on systems where additional
patches modify the following condition in open_file()
if ((open_access_mask & (FILE_READ_DATA|FILE_WRITE_DATA|FILE_APPEND_DATA|FILE_EXECUTE)) ||
(!file_existed && (local_flags & O_CREAT)) ||
((local_flags & O_TRUNC) == O_TRUNC) ) {
to
if ((open_access_mask & (FILE_READ_DATA|FILE_WRITE_DATA|FILE_APPEND_DATA|FILE_EXECUTE|DELETE_ACCESS)) ||
(!file_existed && (local_flags & O_CREAT)) ||
((local_flags & O_TRUNC) == O_TRUNC) ) {
Ie addtionally check open_access_mask against DELETE_ACCESS. As a result
opens with DELETE_ACCESS go through the code that does an fd_open() plus
a subsequent fstat().
That will trigger a crash in fruit_fstat_meta_stream() when a client
wants to delete a file for deletion. When we open base file for delete,
we call open_streams_for_delete() which internally calls create-file
with NTCREATEX_OPTIONS_PRIVATE_STREAM_DELETE which prevents opening of
the base_fsp. Voila, combined with the change described above you get a
NULL deref.

net rpc share allowedusers: Allow restricting shares
The help already implies that you can specify "targets" for net rpc
share allowedusers, but actually the tail end of the command line
is just ignored.
This patch allows a list of shares to be specified, and only those
shares are checked, which can be much faster if you're only interested
in a few shares on a server which exports lots.
This subcommand already accepts an optional filename for the output
of net usersidlist, with a default of stdin. Typically you'd just pipe
one command to the other so stdin is most likely what you want. This
patch adds support for a filename of "-" to mean stdin so that you can
specify stdin explicitly when you provide a list of shares, since in
this case the filename can't be omitted.

Sanity-check that when we use the default lockOutObservationWindow that
user lockout actually works.
The easiest way to do this is to reuse the _test_login_lockout()
test-case, but stop at the point where we wait for the lockout duration
to expire (because we don't want the test to wait 30 mins).
This highlights a problem currently where the default values don't work.
