perf record/report: Add call graph / call chain profiling

Add the first steps of call-graph profiling:

- add the -c (--call-graph) option to perf record
- parse the call-graph record and printout out under -D (--dump-trace)

The call-graph data is not put into the histogram yet, but it
can be seen that it's being processed correctly:

0x3ce0 [0x38]: event: 35
