Doc: update or remove dead external links.

tglsfdc · tglsfdc · commit e91cd951b111 · 2020-07-10T13:16:19.000-04:00
Re-point comp.ai.genetic FAQ link to a more stable address. Remove stale links to AIX documentation; we don't really need to tell AIX users how to use their systems. Remove stale links to HP documentation about SSL. We've had to update those twice before, making it increasingly obvious that HP does not intend them to be stable landing points. They're not particularly authoritative, either. (This change effectively reverts bbd3bdb.) Daniel Gustafsson and Álvaro Herrera, per a gripe from Kyotaro Horiguchi. Back-patch, since these links are just as dead in the back branches. Discussion: https://postgr.es/m/20200709.161226.204639179120026914.horikyota.ntt@gmail.com
