MDEV-12775 Reuse data type aggregation code for hybrid functions and UNION
Introducing a new class Type_holder (used internally in sql_union.cc),
to reuse exactly the same data type attribute aggregation Type_handler API
for hybrid functions and UNION.
This fixes a number of bugs in UNION:
- MDEV-9495 Wrong field type for a UNION of a signed and an unsigned INT expression
- MDEV-9497 UNION and COALESCE produce different field types for DECIMAL+INT
- MDEV-12594 UNION between fixed length double columns does not always preserve scale
- MDEV-12595 UNION converts INT to BIGINT
- MDEV-12599 UNION is not symmetric when mixing INT and CHAR
Details:
- sql_union.cc: Reusing attribute aggregation for UNION.
Adding new methods:
* st_select_lex_unit::join_union_type_handlers()
* st_select_lex_unit::join_union_type_attributes()
* st_select_lex_unit::join_union_item_types()
Removing the old join_types()-based code.
- Changing Type_handler::Item_hybrid_func_fix_attributes()
to accept "name", Type_handler_hybrid_field_type, Type_all_attributes
as three separate parameters instead of a single Item_hybrid_func parameter,
to make it possible to pass both Item_hybrid_func and Type_holder.
- Moving the former special GEOMETRY and ENUM/SET attribute aggregation code
from Item_type_holder::join_types() to
* Type_handler_typelib::Item_hybrid_func_fix_attributes().
* Type_handler_geometry::Item_hybrid_func_fix_attrubutes().
This makes GEOMETRY/ENUM/SET symmetric with all other data types
(from the UNION point of view).
Removing Item_type_holder::join_types() and Item_type_holder::get_full_info().
- Adding new methods into Type_all_attributes:
* Type_all_attributes::set_geometry_type() and
Item_hybrid_func::set_geometry_type().
* Adding Type_all_attributes::get_typelib().
* Adding Type_all_attributes::set_typelib().
- Adding Type_handler_typelib as a common parent for
Type_handler_enum and Type_handler_set, to avoid code duplication: they have
already had two common methods, and we're adding one more shared method.
- Adding Type_all_attributes::set_maybe_null(), as some type handlers
may want to set maybe_null (e.g. Type_handler_geometry) during data type
attribute aggregation.
- Changing Type_geometry_attributes() to accept Type_handler
and Type_all_attributes as two separate parameters, instead
of a single Item parameter, to make it possible to pass Type_holder.
- Adding Item_args::add_argument().
- Moving Item_args::alloc_arguments() from "protected" to "public".
- Moving Item_type_holder::Item_type_holder() from item.cc to item.h, as
now it's very simple.
Btw, this constructor should probably be eventually removed.
It's now used only in sql_show.cc, which could be modified to use
Item_return_decimal (for symmetry with Item_return_xxx created for all
other data types). Or, another option: remove all Item_return_xxx and
use Item_type_holder for all data types instead.

MDEV-12775 Reuse data type aggregation code for hybrid functions and UNION
Introducing a new class Type_holder (used internally in sql_union.cc),
to reuse exactly the same data type attribute aggregation Type_handler API
for hybrid functions and UNION.
This fixes a number of bugs in UNION:
- MDEV-9495 Wrong field type for a UNION of a signed and an unsigned INT expression
- MDEV-9497 UNION and COALESCE produce different field types for DECIMAL+INT
- MDEV-12594 UNION between fixed length double columns does not always preserve scale
- MDEV-12595 UNION converts INT to BIGINT
- MDEV-12599 UNION is not symmetric when mixing INT and CHAR
Details:
- sql_union.cc: Reusing attribute aggregation for UNION.
Adding new methods:
* st_select_lex_unit::join_union_type_handlers()
* st_select_lex_unit::join_union_type_attributes()
* st_select_lex_unit::join_union_item_types()
Removing the old join_types()-based code.

to accept "name", Type_handler_hybrid_field_type, Type_all_attributes
as three separate parameters instead of a single Item_hybrid_func parameter,
to make it possible to pass both Item_hybrid_func and Type_holder.
