// It is possible that the Uploader takes a snapshot but then fails to
// upload it before it is killed. Hence there might be snapshots
// waiting for a later upload. We scan the uploads directory to find
// such files, and upload and delete one at a time as our first
// priority until there are none left. The up_Uploader_upload_now
// function will cause the next snapshot time to be set to current
// time, but that is it, the snapshot will not actually be taken
// before any old files have been handled.

// Sets the full pathname to *pathname.
// This sets *pathname to NULL if there are no more files.
// The caller must free any set pathname.
