Fix tftp return codes and tsize upload handling

Browse Source 
Error codes were not properly returned to the main curl code (and on to apps
using libcurl).

tftp was crapping out when tsize == 0 on upload, but I see no reason to fail
to upload just because the remote file is zero-length.  Ignore tsize option on
upload.
