[openadk] new website

Hi, I updated the websites for my embedded linux projects today. If you have any issues to access anything, please sent me an email. I got bored by Trac and now static websites generated with hugo, and gogs for wiki/issue/git is in use. The cgit interface and mailman are still the same. I switched to the faster git http backend for cloning via http/https. I moved on to new certbot and all websites are forced to https. Some minor content (C library matric/ Debugging hints will be added soon). Thanks to Simone for my new black labrador logo abstracted from a real photo of my dog. best regards Waldemar
