Problem:
=======
MariaDB's command line utilities (e.g., mysql,
mysqldump, etc) silently ignore connection
property options (e.g., --port and --socket)
when protocol is not explicitly set via the
command-line for localhost connections.
Fix:
===
If connection properties are specified without a
protocol, override the protocol to be consistent.
For example, if --port is specified, automatically
set protocol=tcp.
Caveats:
=======
* When multiple connection properties are
specified, nothing is overridden
* If protocol is is set via the command-line,
its value is used

Also fixes:
MDEV-21487: Implement option for mysql_upgrade that allows root@localhost to be replaced
MDEV-21486: Implement option for mysql_install_db that allows root@localhost to be replaced
Add user mariadb.sys to be definer of user view
(and has right on underlying table global_priv for
required operation over global_priv
(SELECT,UPDATE,DELETE))
Also changed definer of gis functions in case of creation,
but they work with any definer so upgrade script do not try
to push this change.
Don't distinguish between a "password hash" and "authentication string"
anymore. Now both are stored in mysql.user.authentication_string, both
are handled identically internally. A "password hash" is just how some
particular plugins interpret authentication string.
Set mysql.user.plugin even if there is no password. The server will use
mysql_native_password plugin in these cases, let's make it expicit.
Remove LEX_USER::pwhash.
