pulled into DiagnosticNoteRenderer, and common DiagnosticRenderer that
assumes that all custom diagnostic messages are notes. Also extend
DiagnosticRenderer to work with StoredDiagnostics in preparation for
subsequent changes.

-Allow it to be used with multiple BeginSourceFile/EndSourceFile calls; for this introduce
a "finish" callback method in the DiagnosticConsumer. SDiagsWriter finishes up the serialization
file inside this method.
-Make it independent of any particular DiagnosticsEngine; make it use the SourceManager of the
Diagnostic object.
-Ignore null source ranges.

The motivation for this new DiagnosticConsumer is to provide a way for tools invoking the compiler
to get its diagnostics via a libclang interface, rather than textually parsing the compiler output.
This gives us flexibility to change the compiler's textual output, but have a structured data format
for clients to use to get the diagnostics via a stable API.
I have no tests for this, but llvm-bcanalyzer so far shows that the emitted file is well-formed.
More work to follow.
