* stdlib/bits/stdlib.h (mbstowcs): Divide __bos (__dst) by
sizeof (wchar_t) rather than multiplying __len by sizeof (wchar_t). Pass __bos (__dst) / sizeof (wchar_t) to the *_chk routine. * wcsmbs/bits/wchar2.h (mbsrtowcs, mbsnrtowcs): Likewise. * debug/mbsnrtowcs_chk.c (__mbsnrtowcs_chk): Don't multiply len by sizeof (wchar_t). * debug/mbsrtowcs_chk.c (__mbsrtowcs_chk): Likewise. * debug/mbstowcs_chk.c (__mbstowcs_chk): Likewise. Fix type of SRC argument. Pass &SRC rather than SRC to __mbsrtowcs. * debug/wcstombs_chk.c (__wcstombs_chk): Pass &SRC rather than SRC to __wcsrtombs. * debug/tst-chk1.c: Include assert.h. (do_test): Change enough array from VLA into a fixed size array. Assert that MB_CUR_MAX is <= sizeof (enough). Use FAIL () macro instead of print error details. Add several new tests. Kill some unused variable warnings.
