All of the trace options that require code edits to enable them are in
one place now. No need to re-invent what is already there.

The chapter is about Trace generally. DTrace isn't the only way of
getting trace information out of the server, so why would it have it's
own private chapter?

I had split the Developer options into 2, which was a neat split. There
are tracing parameters and recovery/other parameters. So the split was
neither random, nor hidden - there was a clear xref to them from the
config.sgml. (That was one of the causes of the SGML errors, note).

The trace related parameters are significantly different from other
parameters, since they do not always work.
