Improve bignum support for system types

Use bignums when Emacs converts to and from system types like
off_t for file sizes whose values can exceed fixnum range.
Formerly, Emacs sometimes generted floats and sometimes ad-hoc
conses of integers.  Emacs still accepts floats and conses for
these system types, in case some stray Lisp code is generating
them, though this usage is obsolescent.

Document changes.
* src/bignum.c (mpz_set_uintmax, make_biguint)
(mpz_set_uintmax_slow, bignum_to_intmax, bignum_to_uintmax):
New functions.
(mpz_set_intmax_slow): Implement via mpz_limbs_write,
to avoid the need for an extra pass through a negative number.

If an integer is out of fixnum range, use a bignum
instead of converting it to a float or a cons of integers.
