Implement handling of restartable conversion functions according to
ISO C.
* iconv/gconv.h (__gconv_fct): Add additional parameter.
* iconv/gconv_int.h (__BUILTIN_TRANS): Likewise.
* iconv/gconv.c: Pass additional parameter to conversion function.
* iconv/gconv_simple.c (internal_ucs4_loop_single): New function.
(internal_ucs4le_loop_single): New function.
(__gconv_transform_ascii_internal): Define ONE_DIRECTION.
(__gconv_transform_internal_ascii): Likewise.
(__gconv_transform_internal_utf8): Likewise.
(__gconv_transform_utf8_internal): Likewise.
(__gconv_transform_ucs2_internal): Likewise.
(__gconv_transform_internal_ucs2): Likewise.
(__gconv_transform_ucs2reverse_internal): Likewise.
(__gconv_transform_internal_ucs2reverse): Likewise.
(internal_ucs4le_loop_unaligned): Before return
__GCONV_INCOMPLETE_INPUT check that the remaining bytes really form
a valid character. Otherwise return __GCONV_ILLEGAL_INPUT.
(__gconv_transform_utf8_internal): Define STORE_REST and UNPACK_BYTES.
* iconv/loop.c: Fit in definition of function to convert one character
for processing of left-over bytes from the state object.
* iconv/skeleton.c (gconv): Rename inbuf to inptrp and inbufend to
inend to match names in loop functions.
(RESET_INPUT_BUFFER): Change apprpriately.
(gconv): If needed, call function to process bytes from the state
object. Similar at the end: store left over bytes if input is
incomplete.
Take extra argument and add new argument to all calls of the
conversion function.
* iconvdata/iso-2022-cn.c: Adjust numeric values used to store
information in the state object to not conflict with length count.
* iconvdata/iso-2022-jp.c: Likewise.
* iconvdata/iso-2022-kr.c: Likewise.
* iconvdata/unicode.c: Adjust for change change in parameters of
skeleton function.
* iconvdata/utf-16.c: Likewise.
* libio/iofwide.c: Add new parameter to all calls of conversion
function.
* wcsmbs/btowc.c: Likewise.
* wcsmbs/mbrtowc.c: Likewise.
* wcsmbs/mbsnrtowcs.c: Likewise.
* wcsmbs/mbsrtowcs.c: Likewise.
* wcsmbs/wcrtomb.c: Likewise.
* wcsmbs/wcsnrtombs.c: Likewise.
* wcsmbs/wcsrtombs.c: Likewise.
* wcsmbs/wctob.c: Likewise.
* iconvdata/gbgbk.c: Always define MAX_NEEDED_OUTPUT and
MAX_NEEDED_INPUT.
