When opening a repository, it will call `ensureValidRepository` and also `CatFileBatch`. But sometimes these will not be used until repository closed. So it's a waste of CPU to invoke 3 times git command for every open repository. This PR removed all of these from `OpenRepository` but only kept checking whether the folder exists. When a batch is necessary, the necessary functions will be invoked. --- Conflict resolution: Because of the removal of go-git in (#4941) `_nogogit.go` files were either renamed or merged into the 'common' file. Git does handle the renames correctly, but for those that were merged has to be manually copied pasted over. The patch looks the same, 201 additions 90 deletions as the original patch.
