perf, tools: Refactor and support interval and CSV metrics v3
[v3: Addressed all review feedback. Update manpage for CSV. Various changes (see individual patches). Remove some more redundant code in printout callers.] [v2: Addressed (near) all review feedback. No manpage updates so far. Add support for --per-core metrics. Various cleanups.] [v3: Everything compiles again. Some more cleanups.] Currently perf stat does not support printing computed metrics for interval (-I xxx) or CSV (-x,) mode. For example IPC or TSX metrics over time are quite useful to know. This patch implements them. The main obstacle was that the metrics printing was all open coded all over the metrics computation code. The second patch refactors the metrics printing to work through call backs that can be more easily changed. This also cleans up the metrics printing significantly. The indentation is now handled through printf, no more need to manually count spaces. Then based on that it implements metrics printing for CSV and interval mode.

The second patch refactors the metrics printing to work through call backs that can be more easily changed. This also cleans up the metrics printing significantly. The indentation is now handled through printf, no more need to manually count spaces. Then based on that it implements metrics printing for CSV and interval mode.
