Adds gettext support in Grub. Building system needs to be improved and maybe userland utilites improved.
YYYY-MM-DD Carles Pina i Estany <carles@pina.cat> * Makefile.in: Add uptrans target to help to update .pot file * conf/common.rmk: Add grub-gettext_lib target, dependency and SOURCES, CFLAGS, LDFLAGS * kern/misc.c: Define grub_gettext symbol and add implement grub_gettext_dummy function * po/TODO: Temporary file with instructions of what Makefile.in will do * po/ca.po: Catalan translation stub * include/grub/misc.h: Define macro _(char *s). Declare grub_gettext_dummy and grub_gettext * gettext/gettext.c: New file with gettext implementation * normal/menu.c (print_message): add _( ) to some strings * util/grub.d/10_linux.in: include grub-gettext_lib file. For the Linux menuentry, call eval_gettext * util/grub.d/00_header.in: add locale_prefix and gettext locale detection and setting up the access to the mo directory * util/grub-mkconfig_lib.in: add get_locale_lang * util/grub-gettext_lib.in: new file
