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

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

* 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.
