* lisp.h (struct vectorlike_header, struct Lisp_Subr):  Signed sizes.

Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
well either way, and we prefer signed to unsigned.

 	Random fixes.  E.g., (random) never returned negative values.
 	* fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
 	subseconds part to the entropy, as that's a bit more random.
