[PATCH v5 0/4] PR gdb/31353

[Markus Metzger <markus.t.metzger@intel.com>]

Reviving an old patch series that was first submitted in Jan'21.

It fixes issues with breakpoints at the end of the execution history,
including PR gdb/31353, which was submitted in the meantime.

Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=31353

Guinevere Larsen reviewed most of the series and reported an issue with
applying the last patch.  I'm resending the series, rebased on current
master, to hopefully fix that issue.

The only change to v4 is that a redundant forward declaration was removed.

The changes are mostly in infrun and require global maintainer approval.

Markus Metzger (4):
  gdb, infrun, btrace: fix reverse/replay stepping at end of execution
    history
  gdb, infrun, record: fix hang when step-over fails with no-history
  gdb, infrun, record: move no-history notification into normal_stop
  gdb, infrun: fix multi-threaded reverse stepping
