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.

1.3.0

least it should no longer cause a compiler error. However, it does not have
AI_NUMERICHOST so we cannot getaddrinfo() any numerical addresses with it (we
use that for FTP PORT/EPRT)! So, I modified the configure check that checks if
the getaddrinfo() is working, to use AI_NUMERICHOST since then it'll fail on
AIX 4.3 and it will automatically build with IPv6 support disabled.

to survive without it if not found. AIX 4.3 targetted adjustment.

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

--trace, --trace-ascii and --verbose output. I also made the '>' display
separate each line on the linefeed so that HTTP requests etc look nicer in the
-v output.

a pidfile for the server appears as otherwise it failed.

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

pointing out the CA cert path/file: SSL_CERT_DIR and SSL_CERT_FILE. If
CURL_CA_BUNDLE is not set, they are checked afterwards.

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

body there is nothing chunked-encoded!

we should make it do that...)

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