dd: make status=none suppress all diagnostics

Browse Source 
* src/dd.c (STATUS_NONE): Simplify the enum so that
it's more general than just suppressing transfer counts.
Then test this in all locations where non fatal diagnostics
are output.
* tests/dd/misc.sh: Ensure the diagnostic about
being unable to skip past the end of input is suppressed.
* NEWS: Mention the change in behavior.
Fixes http://bugs.gnu.org/14897
