branches/zip: Implement the reporting of duplicate key values to MySQL. innobase_rec_to_mysql(): New function, for converting an InnoDB clustered index record to MySQL table->record[0]. TODO: convert integer fields. Currently, integer fields are in big-endian byte order instead of host byte order, and signed integer fields are offset by 0x80000000. innobase_rec_reset(): New function, for resetting table->record[0]. row_merge_build_indexes(): Add the parameter TABLE* table (the MySQL table handle) for reporting duplicate key values. dtuple_from_fields(): New function, to convert an array of dfield_t* to dtuple_t. dtuple_get_n_ext(): New function, to compute the number of externally stored fields. row_merge_dup_t: Structure for counting and reporting duplicate records. row_merge_dup_report(): Function for counting and reporting duplicate records. row_merge_tuple_cmp(), row_merge_tuple_sort(): Replace the ulint* n_dup parameter with row_merge_dup_t* dup. row_merge_buf_sort(): Add the parameter row_merge_dup_t* dup, which is NULL when sorting a non-unique index. row_merge_buf_write(), row_merge_heap_create(), row_merge_read_rec(), row_merge_cmp(), row_merge_read_clustered_index(), row_merge_blocks(), row_merge(), row_merge_sort(): Add const qualifiers. row_merge_read_clustered_index(): Use a common error handling branch err_exit. Invoke row_merge_buf_sort() differently on unique indexes. row_merge_blocks(): note TODO: We could invoke innobase_rec_to_mysql() to report duplicate key values when creating a clustered index.

branches/zip: Correctly convert InnoDB records to MySQL table->record[0]. innobase_col_to_mysql(): New function, adapted from row_sel_field_store_in_mysql_format(). innobase_rec_to_mysql(): Correct the function comment, which was still saying "clustered index record", although we can convert any record. Make use of innobase_col_to_mysql(). Always call field->reset(), so that innobase_col_to_mysql() will not have to pad anything.

branches/zip: Add a UNIV_INTERN qualifier to every global function declaration in *.h files, so that the function signatures in the *.h and *.c files fully match each other. ut_dulint_sort(): Add a UNIV_INTERN qualifier also to the function definition.
