Move xml_gen tool to its own separate directory

I guess make spec in ejabberd will fail because xml_gen.beam is not in ebin directory anymore.

Why should it be in ebin ?

Makefile is doing:

        erlc -o tools -I include tools/xml_gen.erl
        erl -noinput +B -pa tools -eval 'case xml_gen:compile("tools/xmlrpc_codec.spec") of ok -> halt(0); _ -> halt(1) end.' 

Erlang path is pointing to tools.

Because ejabberd doesn't see 'tools' directory of p1_xml, only 'ebin': https://github.com/processone/ejabberd/blob/master/Makefile.in#L109

ejabberd is not involved in my test. I only do:

1. clone p1_xml and configure
2. call make xmlrpc-codec, as I have added make target to generate that .erl file.

That the

As commented by Evgeny: ejabberd rebuilds xmpp spec on each build and needs xml_gen.beam for that. Theorically, it should be more a new rebar plugin or mix compiler.
