Subject: [flags] Deprecate is_silent/is_verbose in favor of single flag.

Today, both modes are controlled by a single flag, however this is a
bit misleading as is_silent really means "quiet", that is to say `coqc
-q` whereas "verbose" is Coq normal operation.

We also restore proper behavior of goal printing in coqtop on quiet
mode, thanks to @Matafou for the report.
