fixes after merge of 4.1.

mysql-test/r/subselect.result:
  correcting non-ascii chars hosed by automerge as usual
mysql-test/t/subselect.test:
  correcting non-ascii chars hosed by automerge as usual
sql/log_event.cc:
  correcting bad manual merge. ZERO_LEN is not needed in 5.0, as ::exec_event() just tell()s the relay log instead
  of using get_event_len().
sql/log_event.h:
  get_event_len() is not needed in 5.0, ZERO_LEN neither.
sql/slave.cc:
  fixes to take into account 5.0 specificities in replication. ZERO_LEN is not needed.
