* Replace linkRegex with xurls library Rather than maintaining a complicated regex to match URLs for autolinking, gitea can use this existing go library that takes care of the matching with very little code change to gitea itself. After spending a while trying to find the perfect regex for all cases this library still works better as it is more flexible than a single regex ever will be. This will also fix the following issues: #5844 #3095 #3381 This passes all our current tests and I've added new ones mentioned in those issues as well. * Use xurls.StrictMatchingScheme instead of xurls.Strict This is much faster and we only care about https? links to preserve existing behavior.
