[stunnel-users] Check IP or Name of Client Or Server by Common Name

Hi all, I have made patch for stunnel-4.43. It helps you to switch on in the file of stunnell.conf new features, the option name is verify_peer. you can read more about it after patching, compiling and running the command "stunnel --help". The goal of this option to verify clients or servers "ip addreses or names of ip-addreses" with "Common name" of certificate. This option is very flexible and usable. It's possible to switch it of or use it as in field of global options and in service-level options. verify_peer = client_name | client_ip | remote_name | remote_ip
