Fixed compiler warnings

Fixed some wrong test cases
Fixed bug in null handling in XtraDB


extra/comp_err.c:
  Fixed compiler warnings
extra/my_print_defaults.c:
  Fixed compiler warnings
mysql-test/suite/binlog/t/binlog_killed.test:
  Added support for timeouts
mysql-test/suite/funcs_1/r/is_columns_is.result:
  Updated results (INNODB_SYS_TABLES had got new column)
scripts/mysql_install_db.sh:
  Fixed typo
sql/mysql_priv.h:
  Removed not needed argument for compare_record()
sql/sql_insert.cc:
  Removed not needed argument for compare_record()
sql/sql_update.cc:
  Removed not needed argument for compare_record()
  The argument is not needed becasue we copy the full record[0] to record[1] and the comparison should work even if all columns are not read
sql/table.cc:
  The comparison of rows is independent of HA_PARTIAL_COLUMN_READ
storage/maria/maria_chk.c:
  Fixed compiler warnings
storage/maria/maria_read_log.c:
  Fixed compiler warnings
storage/myisam/myisamchk.c:
  Fixed compiler warnings
storage/myisam/myisampack.c:
  Fixed compiler warnings
storage/xtradb/dict/dict0load.c:
  Fixed compiler warnings
storage/xtradb/row/row0sel.c:
  Fixed null handling in XtraDB. (See comment)
storage/xtradb/trx/trx0sys.c:
  Fixed compiler warnings
support-files/compiler_warnings.supp:
  Fixed compiler warnings
