WL#5510 Functions to_base64 and from_base64
@ mysql-test/include/ctype_numconv.inc
@ mysql-test/r/ctype_binary.result
@ mysql-test/r/ctype_cp1251.result
@ mysql-test/r/ctype_latin1.result
@ mysql-test/r/ctype_ucs.result
@ mysql-test/r/ctype_utf8.result
@ mysql-test/r/func_str.result
@ mysql-test/t/func_str.test
Adding tests
@ mysys/base64.c
Rewriting base64_decode, it's now 30% faster
(using array instead of of strchr helps with that),
and rejects garbage in input.
@ sql/item_create.cc
Adding creators
@ sql/item_strfunc.cc
Implementing Item_func_to_base64 and Item_func_from_base64
@ sql/item_strfunc.h
Adding prototype for Item_func_to_base64 and Item_func_from_base64
modified:
