A) Normal non-proxy HTTP:

 - no more "Pragma: no-cache" (this only makes sense to proxies)

B) Non-CONNECT HTTP request over proxy:

 - "Pragma: no-cache" is used (like before)

 - "Host: [name]:[port]"
 - "Proxy-Connection: Keep-alive"

but we could use having a look at ares/config.h when that is used

debug builds only. Made the ftp code use it on several places.

detects a bad Ipv6 situation and disables it automatically)

HTTP test server is a bit limited though, as it never responds to the POST
request until all data has been sent (and received)...

for the given test case. This should fix the cases where the server can run
but curl cannot work with it.
