tools: Allow processing instructions in some XML parsing tools IANA registry files have XSLT references, which are harmless to ignore.

util.xml: Add an option to allow <?processing instructions?> These should generally be safe to just ignore, which should be the default behavior of Expat and LuaExpat

mod_http: Use interface name as default default global hostname http://[::]:5280/ is as sensible as http://*:5280/ so why not This might be a bit weird when listening no multiple interfaces but not sure we can really do anything sensible then anyway.

mod_http: Use http_default_host for URLs generated in global context This might make the global routes less confusing sometimes, or at least valid URLs instead of http://*:5280/ which doesn't make much sense.

prosodyctl: Allow passing server on command line with --server Because why not I guess. This mirrors the corresponding luarocks command

prosodyctl: Allow install plugin via explicit path or URL This way you don't need to set the server URL in the config to use this, you could just ^C^V an install line from a web page that says prosodyctl install https://modules.example.com/mod_example.src.rock Drop the help message in this case since it'll be all messed up by being given an URL or rock filename.

prosodyctl: Return success status code from --help Only when the help is shown because of invalid arguments should a non-zero status code be returned to indicate a problem.

prosodyctl: Use argument parsing library to parse --help, -h, -? Reads nicer, but adds more code. Can always be reverted later I suppose.

mod_websocket: Only enable host-agnostic HTTP routing when enabled globally This way the host-agnostic http://*:5280/ handler is not enabled, but BOSH can still be used with any local VirtualHost Ref #1712

mod_bosh: Only enable host-agnostic HTTP routing when enabled globally This way the host-agnostic http://*:5280/ handler is not enabled, but BOSH can still be used with any local VirtualHost Ref #1712
