The basic functionality could be made like this:

We consider a case where we automaticly enable this is if we do PUT without a
known size. We append the proper header to the request and...

When we read data using the callback (around lib/transfer.c:900), we should
save a little extra data *before* the buffer where we read the new data into
(and an extra two bytes afterwords for a CRLF to get appended). Given that we
only deal with 32bit length, we need 10 bytes saved.

When we know how much data we received, we prepend "[SIZE in hex] CRLF" to
the data buffer and then we send that whole buffer to the server.

Repeat.

When the 0 is read from the callback, indicating end of data, we create a
terminating zero-length chunk and sends away that.

Done.
