Remove --disable-quiet and quiet mode, default to a sane behavior

This patch is a follow-up to 1f1c2e0 which introduced the new semantics
for the very confusing quiet and silent modes.

The initial idea was to loosely follow the kernel cmdline 'quiet' option
and as a working concept this was good.  The resulting code, however,
became unnecessarily complex and the configure options impossible to
explain.

With this patch the quiet mode, and thus the --disable-quiet configure
option, is removed.  Finit now defaults to a sane behavior: services are
shown only at startup.   The --enable-silent option works like it did
before, silencing everything.
