    Avoid x^0 and Order(x^0) terms together in series expansion.
    
    At the branch cut, the series expansions of log(), atan(), and atanh()
    assembled pseries objects which contained both x^0 and Order(x^0) terms.
    This patch removes the extra x^0 term if the order is 0. It also adds
    a GINAC_ASSERT for these kinds of invariants to the pseries ctor and
    simplifies the loops in pseries' degree(), ldegree(), eval() and evalf()
    member functions.
