Log Message:
add timeout for ssl connect

Implement a timeout for SSL connection setup, using -q QUITTIME,
defaulting to 60 seconds.
SSL_connect(3) (unlike connect(2)) doesn't timeout by default.

Adapt ssl error messages destination: if unexpected error
from local API, use warn()/warnx() to stderr;
if expected error from a network operation (e.g., timeouts),
use fprintf to ttyout (which might be stdout).

Consistently use ftp_poll() instead of select();
ssl.c (using select()) was added 7 years after the
previous uses of select() were converted to poll().

Check EAGAIN as well as existing EINTR error from ftp_poll(),
for portability.
