Gitea writes its own AppPath into git hook scripts. If Gitea's AppPath changes, then the git push will fail. This PR: * Introduce an AppState module, it can persist app states into database * During GlobalInit, Gitea will check if the current AppPath is the same as last one. If they don't match, Gitea will sync git hooks. * Refactor some code to make them more clear. * Also, "Detect if gitea binary's name changed" #11341 is related, we call models.RewriteAllPublicKeys to update ssh authorized_keys file
