[Breaking]
Good news:
GCC now checks your `my_snprintf` (direct) calls (`-Wformat` was on);
Bad news:
The build process no longer lets your incorrect
formats/arguments sneak past (`-Werror` was also on).
As such, this commit also migrates all direct `my_snprintf` calls from
the old specifiers to MDEV-21978’s new `-Wformat`-compatible suffixes.
The next commits will cover non-direct calls to `my_snprintf`.
(I call them “`my_snprintf` descendants”.)
This commit does not update the ABI records because
there’re more ABI “changes” to come – half a dozen
`include/mysql/plugin_*.h.pp`s are now missing the new `__attribute__`s.
To make this possible, it was also necessary to enhance the mariadb
client with the option --print-query-on-error.
This option can also be very useful when running a batch of queries
through the mariadb client and one wants to find out where things goes
wrong.
TODO: It would be good to enhance mariadb_upgrade to not call the mariadb
client for executing queries but instead do this internally. This
would have made this patch much easier!

- Prevent opening of any user tables in case `upgrade-system-table`
option is used.
- Still there may be uninstalled data types in `mysql` system table so
allow it to perform.
- Closes PR #2790
- Reviewer: <daniel@mariadb.org>, <vicentiu@mariadb.org>
- Moved view checks after privilege tables are fixed. This is to avoid
warnings about wrongly defined mysql.proc when checking views.
- Don't use stat tables before they have been fixed.
- Don't run mysql_fix_view() if 'FOR MYSQL' is used if the view is
already a MariaDB view.
- Added 'FOR UPGRADE' as an option for 'REPAIR VIEW' to be able to
detect if the REPAIR command comes from mariadb_upgrade. In this
case we get a warning, instead of an error, if a definer of a view
does not exists.
These are mainly internal files so is a low impact change.
The few scripts/mysql*sql where renames to mariadb_* prefix
on the name.
mysql-test renamed to mariadb-test in the final packages
Renames the upgrade state file, and ensures the old
file is properly removed when `mariadb-upgrade` tool is executed.
