upload: warn users trying to upload from stdin with anyauth

Browse Source 
Since uploading from stdin is very likely to not work with anyauth and
its multi-phase probing for what authentication to actually use, alert
the user about it. Multi-phase negotiate almost certainly will involve
sending data and thus libcurl will need to rewind the stream to send
again, and it cannot do that with stdin.
