I changed it a bit, mostly by using scm_frame_begin and scm_frame_end
in i18n.c to manage the temporary strings.  Also, there is no need to
validate the arguments when using scm_to_local_string.  See the patch
below.

Do you intend scm_to_lc_category to be part of the public API?  If so,
it will have to be documented, of course.  I have made it internal for
now.
