• IMAP in multi mode does SSL connections non-blocking
• honours the --disable-ldaps configure option
• Force setopt constants written by --libcurl to be long
• ssh_connect: treat libssh2 return code better

• SFTP-multi: set cselect for sftp and scp to fix "stall" risk
• configure: removed wrongly claimed default paths
• pop3: fixed torture tests to succeed
• symbols-in-versions: many corrections
• if an HTTP request gets retried because the connection was dead, rewind if any data was sent as part of it
