from Lawrence D'Oliveiro (ldo) More use of bool type, necessitating adding inclusion of BLI_utildefines.h, or moving it up in the inclusion order if it was already included, in various places - storage.c: make some variables only used in bli_builddir local to that - storage.c: BLI_file_descriptor_size should allow 0 as a valid file descriptor - path_util.c: make pointers to non-reentrant storage returned from folder routines const, necessitating making variables holding these returned pointers const elsewhere as well - path_util.c: BLI_string_to_utf8 closes iconv context in case of conversion error - blf_lang.c: fill_locales routine now has its own "languages" local variable to construct paths (was stealing internal storage belonging to BLI_get_folder before)
