Obtain upload lock before uploading

Before uploading, the system will now set the status as uploading in
order to have more control of the upload process and status.
Without that the UI status updates could show up incorrectly.
Also, this behaviour removes the need to upload a file to set the
upload in progress, which avoids a concurrent upload try to upload
a file if there is another upload in progress.
