HS 2.0R2: Add example OSU SPP server implementation
This is meant mainly for testing purposes and as a reference implementation showing how OSU SPP server could be implemented. This is not suitable for any real production use in its current form. Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>

+Hotspot 2.0 OSU server
+======================
+
+The information in this document is based on the assumption that Ubuntu
+12.04 server (64-bit) distribution is used and the web server is
+Apache2. Neither of these are requirements for the installation, but if
+other combinations are used, the package names and configuration
+parameters may need to be adjusted.
+
+NOTE: This implementation and the example configuration here is meant
+only for testing purposes in a lab environment. This design is not
+secure to be installed in a publicly available Internet server without
+considerable amount of modification and review for security issues.
+
+NOTE: While this describes use on Ubuntu 12.04, the version of Apache2
+included in that distribution is not new enough to support all OSU
+server validation steps. In other words, it may be most adapt the steps
+described here to Ubuntu 13.10.
+
+
+Build dependencies
+------------------
+
+Ubuntu 12.04 server
+- default installation
+- upgraded to latest package versions
+ sudo apt-get update
+ sudo apt-get upgrade
+
+Packages needed for running the service:
+ sudo apt-get install sqlite3
+ sudo apt-get install apache2
+ sudo apt-get install php5-sqlite libapache2-mod-php5
+
+Additional packages needed for building the components:
+ sudo apt-get install build-essential
+ sudo apt-get install libsqlite3-dev
+ sudo apt-get install libssl-dev
+ sudo apt-get install libxml2-dev
+
+
+Installation location
+---------------------
+
+Select a location for the installation root directory. The example here
+assumes /home/user/hs20-server to be used, but this can be changed by
+editing couple of files as indicated below.
+
+sudo mkdir -p /home/user/hs20-server
+sudo chown $USER /home/user/hs20-server
+mkdir -p /home/user/hs20-server/spp
+mkdir -p /home/user/hs20-server/AS

+Start RADIUS authentication server
+----------------------------------
+
+cd /home/user/hs20-server/AS
+./hostapd -B as-sql.conf
+
+
+Configure web server
+--------------------
+
+Edit /etc/apache2/sites-available/default-ssl
+
+Add following block just before "SSL Engine Switch" line":
+
+ Alias /hs20/ "/home/user/hs20-server/www/"
+ <Directory "/home/user/hs20-server/www/">
+ Options Indexes MultiViews FollowSymLinks
+ AllowOverride None
+ Order allow,deny
+ Allow from all
+ </Directory>
+
+Update SSL configuration to use the OSU server certificate/key.
+
+Enable default-ssl site and restart Apache2:
+ sudo a2ensite default-ssl
+ sudo a2enmod ssl
+ sudo service apache2 restart
+
+
+Management UI
+-------------
+
+The sample PHP scripts include a management UI for testing
+purposes. That is available at https://<server>/hs20/users.php
+
+
+AP configuration
+----------------
+
+APs can now be configured to use the OSU server as the RADIUS
+authentication server. In addition, the OSU Provider List ANQP element
+should be configured to use the SPP (SOAP+XML) option and with the
+following Server URL:
