Subject: [PATCH] gettext.c: move get_preferred_languages() from http.c
Calling setlocale(LC_MESSAGES, ...) directly from http.c, without
including <locale.h>, was causing compilation warnings. Move the
helper function to gettext.c that already includes the header and
where locale-related issues are handled.
