Subject: WL#1595 "Optionally fsync() the binlog after every statement": New
 option --sync-binlog=x (and global settable variable) which will fsync the
 binlog after every x-th disk write to it. That is, if in autocommit mode,
 after every x-th statement written to the binlog; if using transactions,
 after every x-th transaction written to the binlog. x==0 means no fsync. x==1
 is the slowest. There is no test added for this, I have just checked that it
 works as --sync-binlog=1 dramatically slows down mysqld. Made sync-frm a
 global settable variable.
