Small note: for the deprecation process, we're leaving the old
"trace_mark" macros there for a few UST versions, but they will be
deprecated over time. We might enable compiler warnings in the next
release with the gcc "deprecated" attribute.

As a side-note for this one: by the end of the summer, typical use the
UST instrumentation will be:

TRACEPOINT_EVENT() for declaration
tracepoint(name, ...) in the code.
