(cherry picked from commit 42082e7b)

Waiting for improvements in vlc 4.0, this is a temporary fix to leave
enough time for vlc to get the image after seek. This will not work all
the time but overall improves screenshot accuracy.

(cherry picked from commit 229d92fe)

The smb2 module is back to higher priority again. A lot of bugs has been fixed
since the first release, notably the signing security mode. This fixes
impossible login to smb2 servers, when dsm requested first a login and smb2 was
never tried.

There is also a new patch that prevent to request 2 dialogs from both smb2 and
dsm from the same input. If smb2 login failed, it is useless to request
credentials via the dsm plugin.

PS: if the module smb2 failed because it tried to connect to a smb1 server, it
will fail without requesting any credentials, therefore the dsm module will be
able to request them.
