...to the client address as this frees the RCPT strings to contain
just an email address and by passing the test number into curl as the
client address remains consistent with POP3 and IMAP tests as they are
specified in the URL.
If the mail sent during the transfer contains a terminating <CRLF> then
we should not send the first <CRLF> of the EOB as specified in RFC-5321.
Additionally don't send the <CRLF> if there is "no mail data" as the
DATA command already includes it.
Modified sws to support and use custom CONNECT responses instead of the
previously naive hard-coded version. Made the HTTP test server able to
extract test case number from the host name in a CONNECT request by
finding the number after the last dot. It makes 'machine.moo.123' use
test case 123.
Adapted a larger amount of tests to the new <connect> style.
