MDEV-8379 - SUSE mariadb patches

Fixed unclean prototype declaration. According to ISO/IEC 9899:TC2:
...
10. The special case of an unnamed parameter of type void as the only item in
    the list specifies that the function has no parameters.
...
14. An identifier list declares only the identifiers of the parameters of the
    function. An empty list in a function declarator that is part of a
    definition of that function specifies that the function has no parameters.
    The empty list in a function declarator that is not part of a definition of
    that function specifies that no information about the number or types of the
    parameters is supplied. 124)
...
6.11.6 Function declarators

The use of function declarators with empty parentheses (not prototype-format
parameter type declarators) is an obsolescent feature.
...
