    Convert 703 function definitions to prototype style.
    
    This automatically-generated patch converts 703 function definitions
    in glibc from old-style K&R to prototype-style.
    
    This conversion is deliberately simplistic, excluding any tricky cases
    as even a patch covering only simple cases is still very large.
    Currently excluded are: sysdeps files (to improve test coverage for
    the initial patch); files containing assertions (to avoid line number
    changes so that generated libraries can be compared); any cases where
    the generated function declaration would involve lines over 79
    characters and so need to be wrapped; any cases with array parameters
    or other cases where parameter declarators don't end with the
    parameter name; any other cases that my script didn't parse.
    
    I didn't try to make the ChangeLog generation indicate when function
    definitions are conditional; it just lists the functions changed
    without regard to that.
    
    Tested for x86_64 and x86 (testsuite, and that installed stripped
    shared libraries are unchanged by the patch).
