commit e7e03e47d4113bcac4340bdd83cf5af4991920ad
Author: Johannes Schindelin <address@hidden>

    vtls: introduce a new struct for SSL backends
    
    This new struct is similar in nature to Curl_handler: it will define the
    functions and capabilities of all the SSL backends (where Curl_handler
    defines the functions and capabilities of protocol handlers).
