Refactor editor upload, update and delete to use git plumbing and add LFS support (#5702)

* Use git plumbing for upload: #5621 repo_editor.go: UploadRepoFile * Use git plumbing for upload: #5621 repo_editor.go: GetDiffPreview * Use git plumbing for upload: #5621 repo_editor.go: DeleteRepoFile * Use git plumbing for upload: #5621 repo_editor.go: UploadRepoFiles * Move branch checkout functions out of repo_editor.go as they are no longer used there * BUGFIX: The default permissions should be 100644 This is a change from the previous code but is more in keeping with the default behaviour of git. Signed-off-by: Andrew Thornton <art27@cantab.net> * Standardise cleanUploadFilename to more closely match git See verify_path in: 7f4e641693/read-cache.c (L951) Signed-off-by: Andrew Thornton <art27@cantab.net> * Redirect on bad paths Signed-off-by: Andrew Thornton <art27@cantab.net> * Refactor to move the uploading functions out to a module Signed-off-by: Andrew Thornton <art27@cantab.net> * Add LFS support Signed-off-by: Andrew Thornton <art27@cantab.net> * Update upload.go attribution header Upload.go is essentially the remnants of repo_editor.go. The remaining code is essentially unchanged from the Gogs code, hence the Gogs attribution. * Delete upload files after session committed * Ensure that GIT_AUTHOR_NAME etc. are valid for git see #5774 Signed-off-by: Andrew Thornton <art27@cantab.net> * Add in test cases per @lafriks comment * Add space between gitea and github imports Signed-off-by: Andrew Thornton <art27@cantab.net> * more examples in TestCleanUploadName Signed-off-by: Andrew Thornton <art27@cantab.net> * fix formatting Signed-off-by: Andrew Thornton <art27@cantab.net> * Set the SSH_ORIGINAL_COMMAND to ensure hooks are run Signed-off-by: Andrew Thornton <art27@cantab.net> * Switch off SSH_ORIGINAL_COMMAND Signed-off-by: Andrew Thornton <art27@cantab.net>
