tracing: Add DEFINE_EVENT(), DEFINE_SINGLE_EVENT() support to docbook
The introduction of the new 'DECLARE_EVENT_CLASS()' obviates the
need for the 'TRACE_EVENT()' macro in some cases. Thus, docbook
style comments that used to live with 'TRACE_EVENT()' are now
moved to 'DEFINE_EVENT()'. Thus, we need to make the docbook
system understand the new 'DEFINE_EVENT()' macro. In addition
I've tried to futureproof the patch, by also adding support for
'DEFINE_SINGLE_EVENT()', since there has been discussion about
renaming: TRACE_EVENT() -> DEFINE_SINGLE_EVENT().
Without this patch the tracepoint docbook fails to build.
I've verified that this patch correctly builds the tracepoint
docbook which currently covers signals, and irqs.
Changes in v2:
- properly indent perl 'if' statements
