Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:

New features:

 - Support AArch64 in the 'annotate' code, native/local and
   cross-arch/remote (Kim Phillips)

 - Allow considering just events in a given time interval, via the
   '--time start.s.ms,end.s.ms' command line, added to 'perf kmem',
   'perf report', 'perf sched timehist' and 'perf script' (David Ahern)

 - Add option to stop printing a callchain at one of a given group of
   symbol names (David Ahern)

 - Handle CPU migration events in 'perf sched timehist' (David Ahern)

 - Track memory freed in 'perf kmem stat' (David Ahern)

Infrastructure:

 - Add initial support (and perf test entry) for tooling hooks, starting with
   'record_start' and 'record_end', that will have as its initial user the
   eBPF infrastructure, where perf_ prefixed functions will be JITed and
   run when such hooks are called (Wang Nan)

 - Remove redundant "test" and similar strings from 'perf test' descriptions
   (Arnaldo Carvalho de Melo)

 - Implement assorted libbpf improvements (Wang Nan)
