Integration bug in Maxima 5.14.0



Hello,

While looking at Maxima 5.14.0 for inclusion in Sage, we notice the
following bug.

(%i1) limit( %e^x/x, x, inf);
(%o1)                                inf
(%i2) limit( -%e^x/x, x, inf);
(%o2)                                inf

Also, there were the following regressions:

In 5.13.0
(%i3) integrate(log(1-x^2)/x, x);
(%o3) log(x)*log(1-x^2)+li[2](1-x^2)/2

In 5.14.0
(%i31) integrate(log(1-x^2)/x, x);
(%o31) 1*log(x)*log(1-x^2)-1*((-2)*(-log(1-x^2)/2)*log(x)
                             -2*(log(x)*log(1-x^2)+li[2](1-x^2)/2)/2)

In 5.13.0:
(%i9) bfhzeta(1.1,1/2,50);
Warning:  Float to bigfloat conversion of 12.103813495683745

In 5.14.0:
(%i32) bfhzeta(1.1,1/2,50);
(%o32) 1.210381349568374531600056798197329044342041015625b1
