KNOWN_BUGS: remove five FTP related issues
- "FTP with CONNECT and slow server"

I believe this is not a problem these days.

- "FTP with NULs in URL parts"

The FTP protocol does not support them properly anyway.

- remove "FTP and empty path parts in the URL"

I don't think this has ever been reported as a real problem but was only
a hypothetical one.

- "Premature transfer end but healthy control channel"

This is not a bug, this is an optimization that *could* be performed but is
not an actual problem.

- "FTP without or slow 220 response"

Instead add to the documentation of the connect timeout that the
connection is considered complete at TCP/TLS/QUIC layer.

Closes #9979

.TH CURLOPT_CONNECTTIMEOUT_MS 3 "17 Jun 2014" "libcurl 7.37.0" "curl_easy_setopt options"
.SH NAME
CURLOPT_CONNECTTIMEOUT_MS \- timeout for the connect phase
.SH SYNOPSIS
.nf
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CONNECTTIMEOUT_MS,
long timeout);
.fi
.SH DESCRIPTION
Pass a long. It should contain the maximum time in milliseconds that you allow
the connection phase to the server to take. This only limits the connection
phase, it has no impact once it has connected. Set to zero to switch to the
default built-in connection timeout - 300 seconds. See also the
\fICURLOPT_TIMEOUT_MS(3)\fP option.
In unix-like systems, this might cause signals to be used unless
\fICURLOPT_NOSIGNAL(3)\fP is set.
If both \fICURLOPT_CONNECTTIMEOUT(3)\fP and \fICURLOPT_CONNECTTIMEOUT_MS(3)\fP
are set, the value set last will be used.
The "connection phase" is considered complete when the requested TCP, TLS or
QUIC handshakes are done.
.SH DEFAULT
300000
