[Chilli] uamdomain / uamallowed

[David Bird]

In subversion:

* Added compile time option ''--enable-layer3'' and run-time option
''--layer3'' to enable a Layer3 (IP-Only) style captive portal - no DHCP
* Change to ''chilli_query logout'' to identify sessions based on
options ''sessionid ...'' or ''ip ...'', not just MAC address
* Added compile time option ''--enable-uamdomainfile'' and run-time
option ''--uamdomainfile filename'' to load regex style uamdomains
* Added compile time option ''--enable-redirdnsreq'' and run-time option
''--redirdnsreq'' to have chilli send a DNS query for the hostname found
in the redirect (useful when relying heavily on DNS based walled garden
using ''uamdomain'' or ''uamdomainfile'')
* Fixed ''uamdomain'' such that it will only match exactly the given
name or prefixed with anything dot ('.') name
* Added Pragma no cache and Expires headers to redirect HTTP responses
* Fixed ''chilli_proxy'' bug for when DNS is down
