Subject: [PATCH 09/18] perf tools: Move new_term arguments into struct parse_events_term template

From: Jiri Olsa <jolsa@...nel.org>

We need to add yet another parameter to new_term function in following
patch, so it's better to move first all the current params into template
struct parse_events_term and use it as a single argument.
