replay: implement replay-seek command
This patch adds hmp/qmp commands replay_seek/replay-seek that proceed the execution to the specified instruction count. The command automatically loads nearest snapshot and replays the execution to find the desired instruction count. Signed-off-by: Pavel Dovgalyuk <Pavel.Dovgalyuk@ispras.ru> Acked-by: Markus Armbruster <armbru@redhat.com> -- v4 changes: - fixed HMP command description indent - removed useless error_free call Message-Id: <160174521180.12451.14033112911009278753.stgit@pasha-ThinkPad-X280> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

+# @replay-seek:

+# Automatically proceed to the instruction count @icount, when
+# replaying the execution. The command automatically loads nearest
+# snapshot and replays the execution to find the desired instruction.
+# When there is no preceding snapshot or the execution is not replayed,
+# then the command fails.
+# icount for the reference may be obtained with @query-replay command.
+#
+# @icount: target instruction count

+# Since: 5.2
