zeripath 296814e887 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.

* Standardise cleanUploadFilename to more closely match git

See verify_path in: 7f4e641693/read-cache.c (L951)

* Redirect on bad paths

* Refactor to move the uploading functions out to a module

* Add LFS support

* 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

* 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

* fix formatting

* Set the SSH_ORIGINAL_COMMAND to ensure hooks are run

Signed-off-by: Andrew Thornton <art27@cantab.net>

* Switch off SSH_ORIGINAL_COMMAND
