(strip m_ as prefix from member variables' names)


sql/event.cc:
  - change copyright years
  - remove m_ prefix from member variables (I liked m_)
  - reorder parameter in evex_update_event()
sql/event.h:
  - change copyright years
  - remove m_ prefix from member variables
  - declare some member variables as private (were public)
  - delete 0 is valid in C++ therefore don't embrace with if()
sql/event_executor.cc:
  - executor => scheduler in messages
  - fix a bug introduced in last commit -> typo in a mutex name
  - remove m_ prefix from member variables
sql/event_priv.h:
  - change copyright years
sql/event_timed.cc:
  - change copyright years
  - strip m_ as prefix from member variables' names
sql/sql_parse.cc:
  - strip m_ as prefix from member variables' names
sql/sql_yacc.yy:
  - strip m_ as prefix from member variables names
