 Some complications were in ftp.c. I'm not familiar with that code, so
I tried to change it minimally, hence I left the current "use" flag in
place and added a new state field.

I only have openssl to test with, so the changes to gtls, nss, and
qssl haven't been tested. I noticed that gtls, nss didn't set use to
false on errors. I didn't change that.
Curl_qsossl_connect does set use to FALSE if there's an errror, but
not when Curl_qsossl_handshake fails, which seems inconsistent.

The diff is attached.
