MDEV-28152 wip wip wip alter sequence as <new_value_type>
Basic case:
- start with a narrow value type, the alter to a wider type without
changing any other metadata
Advanced cases to fix once the basic case works:
- start with a wider value type, then alter to a narrower type with
smaller metadata values in range for the narrower value type
- start with a narrower value type, then alter to a wider type with
bigger metadata values out of range for the narrower type but in
range for the wider type
MDEV-28152 create sequences with various signed value types
- Support signed types. Unsigned types to be worked out in the next patch.
- Sequence (definition) tables uses the value type for the field type
of minvalue, maxvalue, startvalue, next_not_cached_value, so that
the value type can be inferred from this type.
This is item 2 of MDEV-28152. When creating a sequence with a huge
minvalue / maxvalue, truncate it to the nearest valid value for the
type, i.e. LONGLONG_MAX - 1 for values >= LONGLONG_MAX and
LONGLONG_MIN + 1 for values <= LONGLONG_MIN

MDEV-29668 SUPER should not allow actions that have fine-grained dedicated privileges
SUPER privilege used to allow various actions that were alternatively
allowed by one of BINLOG ADMIN, BINLOG MONITOR, BINLOG REPLAY,
CONNECTION ADMIN, FEDERATED ADMIN, REPL MASTER ADMIN, REPL SLAVE ADMIN,
SET USER, SLAVE MONITOR.
Now SUPER no longer does that, one has to grant one of the fine-grained
privileges above to be to perform corresponding actions.
On upgrade from MariaDB versions 10.11 and below all the privileges
above are granted automatically if the user has SUPER.
As a side-effect, such an upgrade will allow SUPER-user to run SHOW
BINLOG EVENTS, SHOW RELAYLOG EVENTS, SHOW SLAVE HOSTS, even if he wasn't
able to do it before the upgrade.
This is intended to be the start of a (not complete) coding standards
document we can refer contributors to. This can be modified to add more
nuances and become stricter over time. It can also have additional
content for other file types (CMake, YACC, etc).
It does not cover plugins which should each individually have their own coding
standards.
