This patch fixes compilation with `-trace lttng` or `-trace etw`. We
need to forward declare QEvent, QImageReader etc., otherwise the types
will be unknown while compiling the trace points.
In order to handle this generically, the tracegen utility is extended
to support a 'prefix text' in the `*.tracepoints` input files. Any
text within curly braces will be embedded as-is in the generated file.
This can then be used to add forward declarations for the types we
need, including potential namespaces and such.
