Added two status variables:
binlog_cache_use - counts number of transactions that used somehow
transaction temporary binary log.
binlog_cache_disk_use - counts number of transactions that required
disk I/O for storing info in this this binary log.
include/my_sys.h:
Added disk_writes member to the IO_CACHE structure for counting number
of times when IO_CACHE was forced to write to disk.
mysql-test/r/rpl_relayrotate.result:
Fixed test result since added test for binlog_cache_use and
binlog_cache_disk_use status variables.
mysql-test/t/rpl_relayrotate.test:
Added test for binlog_cache_use and binlog_cache_disk_use status
variables.
Now dropping t1 table on master too.
mysys/mf_iocache.c:
Added disk_writes member to the IO_CACHE structure for counting number
of times when IO_CACHE was forced to write to disk.
sql/handler.cc:
Added support for binlog_cache_use and binlog_cache_disk_use status
variable. First one is incremented if transaction used somehow
transaction temporary binary log (doesn't matter in memory only or
with writes to disk), the second one is incremented if this binary
log was flushed to disk at some point.
sql/mysql_priv.h:
Added declaration of status variables binlog_cache_use and
binlog_cache_disk_use.
sql/mysqld.cc:
Added status variables binlog_cache_use and binlog_cache_disk_use.
