MINOR: cfgparse: SSL/TLS binding in "peers" sections.

Make "bind" keywork be supported in "peers" sections.
All "bind" settings are supported on this line.
Add "default-bind" option to parse the binding options excepted the bind address.
Do not parse anymore the bind address for local peers on "server" lines.
Do not use anymore list_for_each_entry() to set the "peers" section
listener parameters because there is only one listener by "peers" section.

May be backported to 1.5 and newer.
