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.

* wcsmbs/wchar.h (__mbstate_t): Rename elements. Make __value
element a union to allow byte access.
* iconvdata/iso-2022-cn.c: Adjust for change of element name in
mbstate_t.
* iconvdata/iso-2022-jp.c: Likewise.
* iconvdata/iso-2022-kr.c: Likewise.
2000-03-28 Ulrich Drepper <drepper@redhat.com>
* iconvdata/TESTS: Use UCS-2BE instead of UCS2.
* iconv/loop.c: Define get16, get32, put16, and put32 macros to
allow as well reading from/writing to unaligned addresses on machines
which don't support this in hardware. Use FCTNAME macro to define
function name. Include the file a second time for platforms which
need special unaligned handling.
* iconv/skeleton.c: Define get16u, get32u, put16u, and put32u macros
to access potentially unaligned addresses. These macros are intended
to be used only outside the loops.
(unaligned): New definition. In case the machine can handle unaligned
access define as zero. Otherwise as a variable which is initialized
as nonzero in case the buffer passed in at runtime is unaligned with
respect to the character set encoding involved.
Call aligned or unaligned looop functions according to unaligned
variable.
* iconvdata/8bit-gap.c: Use get16, get32, put16, and put32 instead
of direct casting pointer to potentially handle unaligned memory
accesses.
* iconvdata/8bit-generic.c: Likewise.
* iconvdata/ansi_x3.110.c: Likewise.
* iconvdata/big5.c: Likewise.
* iconvdata/euc-cn.c: Likewise.
* iconvdata/euc-jp.c: Likewise.
* iconvdata/euc-kr.c: Likewise.
* iconvdata/euc-tw.c: Likewise.
* iconvdata/gbk.c: Likewise.
* iconvdata/iso-2022-cn.c: Likewise.
* iconvdata/iso-2022-jp.c: Likewise.
* iconvdata/iso-2022-kr.c: Likewise.
* iconvdata/iso646.c: Likewise.
* iconvdata/iso_6937-2.c: Likewise.
* iconvdata/iso_6937.c: Likewise.
* iconvdata/johab.c: Likewise.
* iconvdata/sjis.c: Likewise.
* iconvdata/t.61.c: Likewise.
* iconvdata/uhc.c: Likewise.
* iconvdata/unicode.c: Likewise.
* iconvdata/utf-16.c: Likewise.
* locale/programs/simple-hash.c: Little optimizations. Remove K&R
prototypes.
* malloc/Versions [libc] (GLIBC_2.2): Add mcheck_check_all.
* malloc/mcheck.c (mcheck_check_all): Renamed from check_all and made
public.
* malloc/mcheck.h (mcheck_check_all): Declare.
* stdio-common/Makefile (tests): Add tst-obprintf.
* iconvdata/Makefile (modules): Add ISO-2022-CN.
Add link rules for this module.
(distribute): Add iso-2022-cn.c and cns11643l2.h.
* iconvdata/cns11643l2.h: New file.
* iconvdata/iso-2022-cn.c: New file.
* iconvdata/gconv-modules: Add entries for ISO-2022-CN module.
* iconvdata/cns11643l1.h (cns11643l1_to_ucs4): Make string argument
unsigned.
(ucs4_to_cns11643l1): Likewise.
* iconvdata/euc-tw.c: Correct parameter passed to cns11643l1_to_ucs4.
* iconvdata/iso-2022-kr.c: Remove unnecessary test from conversion
loop to UCS4.
Optimize recognition of escape sequences a bit.
