Update.
* iconv/gconv_simple.c (internal_ucs4le_loop_unaligned): Return
__GCONV_EMPTY_INPUT only if input is really empty. Otherwise
__GCONV_INCOMPLETE_INPUT.
(ucs4le_internal_loop): Likewise.
(ucs4le_internal_loop_unaligned): Likewise.
* iconvdata/unicode.c (PREPARE_LOOP): Likewise.
* iconvdata/utf-16.c (PREPARE_LOOP): Likewise.
* iconvdata/utf-32.c (PREPARE_LOOP): Likewise.
* iconv/loop.c (LOOPFCT): First test for empty input then for full
output buffer.
