Commit 262a9e41 authored by unknown's avatar unknown

Added last_errno and last_error to show slave status

slave will skip the first SQL_SLAVE_SKIP_COUNTER events on start - 
this is needed to recover from broken replication when the next log
event(s) should just be skipped.
Rotate binlogs when max_binlog_size is reached


include/my_sys.h:
  added my_snprintf()

mysql-test/r/rpl000016.result:
  update for additions to the test
mysql-test/t/rpl000016.test:
  test max_binlog_size and slave_skip_counter
mysys/my_vsnprintf.c:
  added my_snprintf()
