MDEV-22380: Assertion `name.length == strlen(name.str)' failed ...bb-10.3-bar-MDEV-22380
Also fixes:
MDEV-25399 Assertion `name.length == strlen(name.str)' failed in Item_func_sp::make_send_field
Also fixes a problem that in this scenario:
SET NAMES binary;
SELECT 'some not well-formed utf8 string';
the auto-generated column name copied the binary string value directly
to the Item name, without checking utf8 well-formedness.
After this change auto-generated column names work as follows:
- Zero bytes 0x00 are copied to the name using HEX notation
- In case of "SET NAMES binary", all bytes sequences that do not make
well-formed utf8 characters are copied to the name using HEX notation.
