mp_is_square says 0 is not a square

[guidovranken]

mp_is_square says 0 is not a square, but it is.

This is the original behaviour (Try git log --follow -p -- mp_is_square.c) and other software, especially LibTomCrypt needs to be checked before we change something here.

But at least the documentation should get an update; the function mp_is_square is listed without a proper description.

Thanks a lot!
