fa25f43ac5 p2p: Remove BIP61 reject messages (MarcoFalke)

Pull request description:

  Reject messages (BIP 61) appear in the following settings:

  * Parsing of reject messages (in case `-debug=net` is set, off by default). This has only been used for a single `LogPrint` call for several releases now. Such logging is completely meaningless to us and should thus be removed.

  * The sending of reject messages (in case `-enablebip61` is set, off by default). This can be used to debug a node that is under our control. Instead of hacking this debugging into the p2p protocol, it could be more easily achieved by parsing the debug log. (Use `-printtoconsole` to have it as stream, or read from the `debug.log` file like our python function `assert_debug_log` in the test framework does)

  Having to maintain all of this logic and code to accommodate debugging, which can be achieved by other means a lot easier, is a burden. It makes review on net processing changes a lot harder, since the reject message logic has to be carried around without introducing any errors or DOS vectors.

    I'm still not 100% convinced that I like getting rid of BIP61 conceptually, but apparently everyone wants it, code review ACK fa25f43ac5.
