libcurl *works* persistant over HTTP proxy!!!!

it saves me from more mistakes when the connectindex is -1 ... also, there's
no point in having its parent do it as all parents would do it anyway.

than 509 letters (as newer gcc warns on with -Wall)

we can re-use a proxy connection that actually has different host names on
the same connection

1.0-reply from a proxy we use and the Proxy-Connection: keep-alive header
is used, we switch it on and live happily ever after

store it.

removed the tiny/Makefile that was added accidentaly before

since they were out-of-date and not correct anymore.

moved around some struct fields

renamed prefixes from curl_ to Curl_
made persistant connections work with http proxies (at least partly)

use the correct prefix

made it work (partly) with persistant connections for HTTP/1.0 replies
moved the 'newurl' struct field for Location: to the connectdata struct

"low leve" interface is dumped

to configure

-Wall and a new gcc

as is the case when doing HEAD requests

version number define in the header file

and used
