Added the required structures and functions for
handing over multiple key ranges to the table handler.

Changed my_error() to print error messages, which come from
arbitrary registered ranges of error messages. Messages can
be unregistered (and should be at end of the program).
Added registration of handler error messages.
Added a new mi_print_error() macro and a new 
mi_report_error() function, which supply error
messages with a table name.
Added calls to mi_print_error() or mi_report_error()
at all places in MyISAM, where table corruption is detected.

We should not call free_tmp_table() for derived table in 
mysql_derived_filling(), since by this moment this table is already
registered in THD::derived_tables list and thus free_tmp_table() will
be called for it automatically in close_thread_tables().
