"http://somehost?data" as it added a slash too much in the request ("GET
/?data/"...). Added test case 260 to verify.

or the test is skipped. Ideally, we should let this test case go over a few
frequently used IPv6 localhost aliases...

Added resolve.c to simply resolve a given host name

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)
 - "Proxy-Connection: Keep-alive" (for older style 1.0-proxies)

C) CONNECT HTTP request over proxy:

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

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

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

download a file from the server before the server is considered fine to use
for the given test case. This should fix the cases where the server can run
but curl cannot work with it.

why sometimes the control connection dies after a RETR has been sent

start... Anyway, fork() + exec() makes _two_ pids (in perl) that we need to
track and kill after use. Thankyouverymuch.

Made the ftp server use the passed in pidfile name, and made runtests.pl
pass it in properly.

a pidfile for the server appears as otherwise it failed.

this happens for some ipv6-enabled hosts on which sockfilt cannot listen
on ipv6.

and sockfilt.c. For good-to-have functions for the servers written in C.

the runtests.pl to check this differently on operating systems that
differentiate on this.

quotes around the contents

and fixed the textmode attribute thing for windows a bit
