Allow music of nominally zero duration to be typeset.

This is important for things like incipits without notes or other
material that produces output without spending time.  In particular,
this is interesting for \score in markup which more often than not
only contains few notational elements and where attempts to just get
basic key/clef/timesignature drawings are sometimes failing in
frustrating manners.

The downside are problems with material that indeed produces no
output.  The basic change is simple and just in
lily/global-context-scheme.cc.  All the rest is attempting to remove
programming errors and warnings occuring for basically empty systems.

The current state is that

\new Staff { }

will segfault, so indeed there is still code that does not expect
actually empty material.

Somebody willing to work somewhat more on this?
