* 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

* 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
