Added second EAP module which uses the hostap libeap to do it's

	Added second EAP module which uses the hostap libeap to do it's
	work.

	Some issues:
	- you have to build hosteap/eap_example/libeap.so yourself
	- if libeap.so is build with TLS, this module REQUIRES tls
	  (certs, etc) and WILL NOT run without it
	- you CANNOT control inner or outer tunneled methods, except
	  by editing the source to this module and (perhaps) the
	  hostap Makefiles
	- the "inner tunnel" sessions are NOT run through a virtual
	  server as with rlm_eap.  This MUST be fixed for production use
	- as a result, the inner tunnele sessions CANNOT be proxied,
	  and they CANNOT have a separate policy applied to them
	- you MUST set "Auth-Type = eap2" manually.
	- you will have to edit this Makefile yourself to get it to
	  build.  No "configure" script is supplied
