Introduce a new mandoc(1) message level, -W style, below -W warning.

Switch -W all from meaning -W warning to meaning -W style.
The meaning of -T lint does *not* change, it still implies -W warning.
No messages on the new level yet, but they will come.

Usually, i do not lightly make the user interface larger.
But this has been planned for years, and EXIT STATUS 1
was reserved for it all the time.  The message system
is now stable enough to finally implement it.

jmc@ regarding the concept: "really good idea"
