* sysdep.c (emacs_read, emacs_write): Check for negative sizes

since callers should never pass a negative size.
Change the signature to match that of plain 'read' and 'write'; see
<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
* lisp.h: Update prototypes of emacs_write and emacs_read.
