decreased the write buffer size to 16KB to perform a lot better on Windows(!)

regular transfer process. This required some new tweaks, like for example
we need to be able to tell the tranfer loop to not chunky-encode uploads
while we're transferring the rest of the request...

make sure that it isn't all sent off in one single send() but instead
really tests the multiple-part-send logic.

with chunked transfer-encoding uploads added

read callback, and thus won't put a lot of stress on the request sending
code (which currently does an ugly loop).

connectdata struct instead, and is no longer modified within the 'set' struct
as previously (which was a really BAAAD thing).

up-to-date with recent changes.

returning back to the select() loop. Consider this a test so far.

complete is now only made for 60 seconds and if no data was received during
those 60 seconds, we store a special error message (preparing to make this
a special error code) as this most likely means that the control connection
has died while we were transferring data.

proper CURLcode. The default timeout for reading one response is now also
possible to change while running.

the necessary directories as specified with -o.

removed old section about problems with old autoconfs, I don't think that
happens anymore
