Replace #28849. Thanks to @yp05327 for the looking into the problem. Fix #28840 The old behavior of newSignatureFromCommitline is not right. The new parseSignatureFromCommitLine: 1. never fails 2. only accept one format (if there is any other, it could be easily added) And add some tests.
Git Module
This module is merged from https://github.com/go-gitea/git which is a Go module to access Git through shell commands. Now it's a part of gitea's main repository for easier pull request.
