Moved the remaining variables, that depends on sql execution, from Relay_log_info to rpl_group_info:
-row_stmt_start_timestamp
-last_event_start_time
-long_find_row_note
-trans_retries

Added slave_executed_entries_lock to protect rli->executed_entries
Added primitives for thread safe 64 bit increment
Update rli->executed_entries when event has executed, not when event has been sent to sql execution thread


sql/log_event.cc:
  row_stmt_start and long_find_row_note is now in rpl_group_info
sql/mysqld.cc:
  Added slave_executed_entries_lock to protect rli->executed_entries
sql/mysqld.h:
  Added slave_executed_entries_lock to protect rli->executed_entries
  Added primitives for thread safe 64 bit increment
sql/rpl_parallel.cc:
  Update rli->executed_entries when event has executed, not when event has been sent to sql execution thread
sql/rpl_rli.cc:
  Moved row_stmt_start_timestamp, last_event_start_time and long_find_row_note from Relay_log_info to rpl_group_info
sql/rpl_rli.h:
  Moved trans_retries, row_stmt_start_timestamp, last_event_start_time and long_find_row_note from Relay_log_info to rpl_group_info
sql/slave.cc:
  Use rgi for trans_retries and last_event_start_time
  Update rli->executed_entries when event has executed, not when event has been sent to sql execution thread
  Reset trans_retries when object is created
