Meson doesn't enjoy the same flexibility we have with Make in choosing
the include path. In particular the tracing headers are using
$(build_root)/$(<D).
In order to keep the include directives unchanged,
the simplest solution is to generate headers with patterns like
"trace/trace-audio.h" and place forwarding headers in the source tree
such that for example "audio/trace.h" includes "trace/trace-audio.h".
This patch is too ugly to be applied to the Makefiles now. It's only
a way to separate the changes to the tracing header files from the
Meson rewrite of the tracing logic.

Code movement in an upcoming patch will show that this file
was implicitly depending on trace-root.h being included beforehand.

To avoid too much duplication add a wrapper that the existing trace
and the new plugin calls can live in. We could move the -strace code
here as well but that is left for a future series as the code is
subtly different between the bsd and linux.
