ChilliSpot Changes

Added the ability to use include <filename> in configuration files to include others. Using gengetopt version 2.16 and a patch is applied to the generated source.
A chilli_radconfig utility to perform a NAS Administrative-User RADIUS login in order to collect configurations (using the new ChilliSpot-Config VSA).
A chilli_query utility to interface directly with the chilli server (via a UNIX socket) and retrieve the status of all DHCP leases and sessions. Also, the utility can be used to instruct chilli to release a DHCP lease (and logout the user).
Added the configuration parameters adminuser and adminpasswd which are used by chilli_radconfig in combination with the other RADIUS (server, secret, port) parameters.
Fixed the handling of the originally requested URL and the forwarding of said in the UAM initial redirect query string (parameter userurl).
Passing query string argument loginurl to uamhomepage noting the URL to follow to login -- also making the redirect return WISPr directions to use the uamserver URL instead.
Added the configuration parameter wwwdir which defines a directory which will serve local files for URLs of format: http://<uamlisten>:<uamport>/www/<filename> - only supports .html, .gif, and .jpg extensions.
Added the configuration parameters dhcpstart, and dhcpend which define the DHCP ippool range.
Added the sending of hisip in the UAM initial redirect query string.
Added the configuration parameter cmdsocket which is the path of the UNIX socket to use for chilli_query.
Added the configuration parameter ssid which gets added to the UAM initial redirect query string.
Added the configuration parameter vlan which gets added to the UAM initial redirect query string.
Added the configuration parameter nasip which gets used in the RADIUS NAS-IP-Address attribute (the listen IP is used if not set).
Added the configuration parameter nasmac which gets sent to the UAM server in the initial redirect query string as called.
Added the configuration parameter uamwispr which turns off and on chilli's internal support for WISPr XML (turned off by default as it is assumed the back-office is driving the XML).
Added the configuration parameter uamsuccess which turns off and on whether or not chilli will send the user back to the UAM server (instead of their original URL) once authenticated.
Swapped input/output octets/packets in RADIUS to be more in-line with other WiFi gateways.
Allocates "app connections" on demand instead of in bulk to reduce memory usage.
Rearranged some code to improve the building process and reduce the memory footprint of the additional utilities.
(Re)Configuration memory leak fixed.
