--cc and working non-blocking sockets uploads

- Mofied the main transfer loop and related stuff to deal with non-blocking

  sockets in the upload section. While doing this, I've now separated the

  connection oriented buffers to have one for downloads and one for uploads

  (as two can happen simultaneously). I also shrunk the buffers to 20K

  each. As we have a scratch buffer twice the size of the upload buffer, we

  arrived at 80K for buffers compared with the previous 150K.

- Added the --cc option to curl-config command as it enables so very cool

  one-liners. Have a go a this one, building the simple.c example:

        $ `curl-config --cc --cflags --libs` -o example simple.c

- I made all socket reads (recv) handle EWOULDBLOCK. I hope nicely. Now we

  only need to address all writes (send) too and then I'm ready for another
