commit 630e59f66af9fcebb56a442f3aef433b0cc1c0e0
Author: Alexei Sheplyakov <alexei.sheplyakov at gmail.com>

    pgcd(): detect relatively prime polynomials properly...
    
    ... so pgcd() doesn't loop forever any more. Division test does not handle
    relatively prime polynomials (because C = 1 divides any polynomial). So we
    should stop interpolation (and return gcd of contents) if we got relatively
    prime images (we should do that for efficiency reasons too).
    
    Thanks to Jörg Arndt for a bug report.
    (cherry picked from commit 6afbb9793e359cf388462c471ea256a6662b0cd4)
