Lighttpd

I just tried to start r1992 using a config file that contained the deprecated proxy-core.check-local option, which made it fail to start. However, I only got the error message when starting with the -D option; using -t to check the config file didn't tell me about it as the pure syntax of the file was ok.

It like to see the -t option enhanced so that it:

1. Performs the current test

2. If that passes, then loads the configured modules

3. Then checks that all options in the configuration file have actually been registered by a module and are not deprecated

4. If this also passes, calls a "test" API function in each loaded module for the module to test for problems specific to its configuration such as nonsensical combinations of configuration options.
