coalesce fields: pid,tid,iaddr,dso
It's allowed to use following combination of fields:
pid - process pid
tid - process tid

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

Store cacheline related entries in nested hist object for each cacheline
data. Nested entries are sorted by 'offset' within related cacheline.
We will allow specific sort keys to be configured for nested cacheline
data entries in following patches.

Adding basic sample processing specific hist_entry allocation callbacks
(via hists__add_entry_ops).
Overloading 'struct hist_entry' object with new 'struct c2c_hist_entry'.
The new hist entry object will carry specific stats and nested hists

Adding bare bones of dimension support for c2c report.
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.
