perf/core improvements and fixes.

perf record:
 
   Alexey Budankov:
 
   - Adapt affinity for machines with #CPUs > 1K to overcome current 1024 CPUs
     mask size limitation of cpu_set_t type.
 
 perf report/top TUI:
 
   Arnaldo Carvalho de Melo:
 
   - Make ENTER consistently present the pop up menu with and without call
     chains, to eliminate confusion. The menu continues available at all times
     use 'm' and '+' can be used to toggle just one call chain level, 'e' for all
     the call chains for a top level histogram entry and 'E' to expand all call
     chains in all top level entries. Extra info about these options was added to
     the pop up menu entries. Pressing 'k' serves as special hotkey to go straight
     to the main vmlinux entries, to avoid having to press enter and then select
     "Zoom into the kernel DSO".
 
 perf sched timehist:
 
   David Ahern:
 
   - Add support for filtering on CPU.
 
 perf tests:
 
   Arnaldo Carvalho de Melo:
 
   - Show expected versus obtained values in bp_signal test.
 
 libperf:
 
   Jiri Olsa:
 
   - Move to tools/lib/perf.
 
   - Add man pages.
 
 libapi:
 
   Andrey Zhizhikin:
 
   - Fix gcc9 stringop-truncation compilation error.
 
 tools lib:
 
   Vitaly Chikunov:
 
   - Fix builds when glibc contains strlcpy(), which is the case for ALT Linux.
