Eliminate byte-compile warnings, with the exception of Stephen's
various non-defined fontconfig functions, as I don't know if he
plans to add them and is keeping the warnings around as a
reminder. The warnings actually eliminated involve i) using mapcar
instead of mapc where the result is discarded and ii) using a
lambda quoted as data in a context where it is unequivocally used
as a function.
