* libc/stdlib/wcstoull_r.c: Add EINVAL return for bad base value,
include wchar.h for prototype, remove extraneous includes, use
C99/POSIX ULLONG_MAX (but allow for poor limits.h).
* libc/stdlib/wcstoull.c: Fix usage comments (mistakes and to add
base value check noted above), remove extraneous includes.
* libc/stdio/asnprintf.c: Add #include "local.h" to get function
prototype for _svfprintf_r().
* libc/stdio/vasnprintf.c: Ditto.
* libc/stdio/local.h: Add function prototype for __submore().
* libc/include/stdio.h: Add function prototypes for _fseeko_r and
_ftello_r.
* libc/posix/namespace.h: Commented out define for write to
eliminate write() prototype being missing for collate.c (which is
the only file that presently includes namespace.h).
* libc/include/reent.h: Added _rename_r.
* libc/reent/renamer.c: Corrected function prototypes in synopses.
* libc/locale/ldpart.c: Use struct stat64 when calling fstat64.
