Main interface functions are:
c2c_hists__init
c2c_hists__reinit
which re/initialize 'struct c2c_hists' object with sort/display entries
string, in a similar way that setup_sorting function does.
We overload the dimension to provide multi line header support for
sort/display entries.
Also we overload base 'struct perf_hpp_fmt' object with 'struct c2c_fmt'
to define c2c specific functions to deal with multi line headers and
spans.
