Simple fixes during review of new code

include/my_global.h:
  Added floatget() to read unaligned flaot
mysql-test/r/select.result:
  Added test for found_rows()
mysql-test/t/select.test:
  Added test for found_rows()
sql/des_key_file.cc:
  Moved initalization of LOCK_des_key_file to mysqld to make simpler code and avoid theoretical race condition
sql/field_conv.cc:
  Added optimizzed varsion of do_cut_string (for simple character sets)
sql/item_func.cc:
  Simplify code (and ensure DBUG_ENTER is excuted before main code)
sql/item_strfunc.cc:
  Safe calculation of max_length
  This was needed as max_length can now be 1<<32-1 (after konstantins recent patch to fix BLOB_LENGTH)
  Remove init_des_key_file() as this is not initialized in mysqld.cc
sql/item_timefunc.cc:
  Safe calculation of max_length
  This was needed as max_length can now be 1<<32-1 (after konstantins recent patch to fix BLOB_LENGTH)
sql/log_event.cc:
  Simplify code
sql/mysql_priv.h:
  Moved initalization of LOCK_des_key_file to mysqld to make simpler code and avoid theoretical race condition
sql/mysqld.cc:
  Moved initalization of LOCK_des_key_file to mysqld to make simpler code and avoid theoretical race condition
  Revert wrong patch of calling close_connection() in first close_connections() loop. (Bug #7403)
  Instead we now print a warning for closed connections only if mysqld is sarted with --warnings
  Added comments to make the close_connections() logic clearer
sql/sql_prepare.cc:
  Use floatget() and doubleget() to protect against unaligned data
sql/sql_select.cc:
  Fixed some cases unlikely cases where found_rows() would return wrong for queries that would return 0 or 1 rows
