[std::]strtoimax and [std::]strtoumax:
They were nearly completely duplicates, i removed the ones with
less/missing configuration.
std::basic_string::empty:
It was found to be redundant because very likely someone forgot to
change "empty" to "clear" when copy&pasting the function names. The
empty function in all these clear functions makes no sense, and the
clear function also was missing.
std::queue::empty and std::array:empty:
They were both twice in the same function name list.
std::string::size, std::wstring::size:
They were already configured with many other size functions above.
std::basic_string::size:
This entry was twice in the same function name list directly one after
another. Very likely one of them should be the length function, which
does simply the same but was missing in the std.cfg.
