Jiri Olsa cd82a32e99 perf tools: Add perf pmu object to access pmu format definition 
Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
  ${sysfs_mount}/bus/event_source/devices/${pmu}/format

Following interface is exported:
  struct perf_pmu* perf_pmu__find(char *name);
  - this function returns pmu object, which is then
    passed as a handle to other interface functions

  int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
                       struct list_head *head_terms);
  - this function configures perf_event_attr struct based
    on pmu's format definitions and config terms data,
    containined in head_terms list.

Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.

Added builtin test 'Test perf pmu format parsing', which could
be run like:
	perf test pmu
