Remove unnecessary reference counts for structs with no gets.  Add
reference count checking to comm_str and mem_info.  Fix memory leaks
and errors detected on "perf mem report" by address sanitizer and leak
sanitizer.

Ian Rogers (8):
  perf ui browser: Don't save pointer to stack memory
  perf annotate: Fix memory leak in annotated_source
  perf block-info: Remove unused refcount
  perf cpumap: Remove refcnt from cpu_aggr_map
  perf comm: Add reference count checking to comm_str
  perf mem-info: Move mem-info out of mem-events and symbol
  perf mem-info: Add reference count checking
  perf hist: Avoid hist_entry_iter mem_info memory leak
