- no user debug callbacks any longer

- no user debug callbacks any longer
- cleanup lately introduced request mess with a serious hack

# now we get the raw sent and received data through
# the curl debug callback -- all that because the "normal"
# interface does not provide us with the response bodies
# for redirects and leaves for instance the transfer encoding
# header intact while decoding the response body
#
# all this kind of stuff breaks the http message parser
#
# too much magic for a library -- all that actions should
# be done by ther CLI or such... well
#
# maybe I can convince the curl people to introduce
# a raw data callback for future versions of libcurl
