If you get errors in linking complaining about common symbols
ld: common symbols not allowed with MH_DYLIB format

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.

  of times when IO_CACHE was forced to write to disk.

  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.

Actually it is not a bug but right behavior observed as pefomance 
degradation after we have forced Item_field::fix_fields() to 
re-execute each time when we are executing prep stmt.

This patch implements small optimization which heals this bad 
behavior. We are caching field position in TABLE::field array in
Item's member and are using this position for speeding up field
lookups in fix_fields() in case of its re-execution.


sql/item.cc:
  Added cached_field_index member to Item_ident for caching field
  position in TABLE::field array for quicker field lookup in case 
  fix_fields() is executed twice.
sql/item.h:
  Added cached_field_index member to Item_ident for caching field
  position in TABLE::field array for quicker field lookup in case 
  fix_fields() is executed twice.
sql/mysql_priv.h:
  Now find_field_in_table has one more in-out parameter which is used
  for caching field index in TABLE::field array stored for quicker
  field look up.
sql/sql_acl.cc:
  Now find_field_in_table has one more in-out parameter which is used
  for caching field index in TABLE::field array stored for quicker
  field look up.
sql/sql_base.cc:
  Optimization: Now when we are looking up Field by its name we are 
  caching its position in TABLE::field array in Item_ident::cached_field_index,
  so when we will call fix_fields() second time for this item (e.g.
  when we are re-executing prep statement) we can reuse this index
  to speed up this lookup.
sql/table.cc:
  Now we storing in TABLE::name_hash pointers to elements of 
  TABLE::field array, because this allows easily retrieve index
  of field in this array when it is looked up by its name.
sql/table.h:
  Added comment claryfying what we store in TABLE::name_hash.
