    [PATCH 2/2] chinrem_gcd: return correct integer content when GCD is a number.
    
    This patch fixes a silly typo and makes chinrem_gcd work correctly with
    polynomials which are "almost" (up to an integer coefficient) relatively
    prime.
    
    Thanks to Ernst Moritz Hahn for a bug report and a test case.
    (cherry picked from commit 00507499530d90533cf029bd503be326d9018138)

    [PATCH 1/2] extract_integer_content: check for rational numbers properly.
    
    Commit 3d09388a (titled as `[bugfix] chinrem_gcd: handle polynomials over
    rationals properly.') broke extract_integer_content: now it always returns 1.
    The check for rational `integer_contnent' introduced by that commit is wrong
    (since integers is a subset of rationals). Rewrite the check proprerly.
    (cherry picked from commit f0fb303711b4334ce59f7da63bfa7cb49f46265f)
