Reject outlandishly-wide bignums

Do not allow bignums that are so wide that their log base 2
might not fit into a fixnum, as this will cause problems elsewhere.
We already have a similar limitation for bool-vectors.
* src/emacs.c (check_bignum_size, xmalloc_for_gmp): New function.
(xrealloc_for_gmp): Check for too-large bignum.
(main): Use xmalloc_for_gmp.
