[PATCH 18/68] perf c2c report: Add header macros

[Arnaldo Carvalho de Melo]

From: Jiri Olsa <jolsa@xxxxxxxxxx>

Adding helping macros to define header objects.  It will be used in
following patches, that add new dimensions.

The c2c report will support 2 line headers, hence we only define
line[0/1] in macros.
