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.

sql/item.cc:
  layout fix
  debug info
sql/sql_class.h:
  removed unused field

   distribution (this is more in line with how "make install" would install
   them) - this should also fix a test failure in the "system_mysql_db_fix"
   test.


BitKeeper/etc/ignore:
  Added cmd-line-utils/libedit/makelist to the ignore list

table resolution".
Added members to Item_ident for storing original db, table and field
names since those that set later from Field have shorter life-time 
than required by prep. stmt. So we need to restore original names in 
Item_ident::cleanup(). Also now using special construnctor for creation
of Item_field from Field object that ensures that table and field name 
have big enough life-time.

"Fix" for bug #2050 "10 to 1 performance drop with server 4.1.1"
Clean ups in implementation of caching of field number in table.
Added caching of table in which field is found in find_field_in_tables().

  Added members to Item_ident for storing original db, table and field
  names since those that set later from Field have shorter life-time

  Added Item_ident::cached_table for caching table there we found 
  our field.

  Added members to Item_ident for storing original db, table and field

  Item_ident::cleanup().
  Changed type of Item_ident::cached_field_index from int to uint
  (and so NO_CACHED_FIELD_INDEX is UINT_MAX now) because we want to
  save one comparison in find_field_in_table().
  Added Item_ident::cached_table for caching table there we found

sql/sql_base.cc:
  find_field_in_table(): small optimization and soime clean ups in 
   caching of field index.
  find_field_in_tables(): added aggresive caching of table in which
   field is found in Item_ident::cached_table.
  insert_fields():
   using special construnctor for creation of Item_field from Field 
   object that ensures that table and field name have big enough life-time.

Marked --no-set-names as deprecated, the name is misleading and --no- in front
makes it cumbersome to use with --disable or --skip prefixes.
The old option will still work for the time being.


client/client_priv.h:
  Added option --set-charset (disable with --skip-set-charset) to mysqldump.
