* Updated "evhtp" restconf mode

* No reliance on libevent or libevhtp, but on libssl >= 1.1 directly
    * Moved out event handling to clixon event handling
    * Moved out all ssl calls to clixon
  * New code MUST use libevhtp from https://github.com/clixon/clixon-libevhtp.git
    * This does NOT work: libevhtp from https://github.com/criticalstack/libevhtp.git
