* 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.
