Rename dired-mark-region choices and ignore empty region.

Browse source 
* lisp/dired.el (dired-mark-region): Rename choices
'exclusive' to 'file', and 'inclusive' to 'line'.
(dired-mark-if, dired-mark): Check for non-empty region explicitly
instead of using use-region-p to ignore non-nil value of
use-empty-active-region.  (Bug#39902)

*** New option 'dired-mark-region' affects all Dired commands that mark files.
When non-nil and the region is active in Transient Mark mode,
then Dired commands operate only on files in the active region.
The values 'exclusive' and 'inclusive' of this option define
the details of marking the last file at the end of the region.
The values 'file' and 'line' of this option define the details of
marking the file at the end of the region.
*** State changing VC operations are supported in dired-mode on files
(but still not on directories).
