Change the DropBoxManager API slightly (this is public, but not yet released) --

take a File instead of a ParcelFileDescriptor (gets opened internally) --
that way the caller doesn't have to worry about closing their PFD and so on.
(Pretty much 100% of the time the caller will be uploading a file, anyway.)
