ftp_ssl_connect peer cert verification

[kronthto]

Description

It would be great if there was a path to transition to secure FTPs connections in PHP.
The current implementation has no peer verification.
However, just patching this now would be a BC break.
A proposal could be an optional parameter that enables a codepath with the typical TLS verification routine (hostname/SAN, cert-dates, trusted signature path).
