> We have a big mess in config file parsing.
> The management API uses {{./mgmt/api/GenericParser.*}} to parse mostly generic key=value syntax, but nothing calls those APIs. We should remove them.
> Internally, other files are parsed by hand (each with a different set of bugs) or by using {{parseConfigLine}}, which was not really intended for generic parsing and has a kind of crappy interface.
> What we need is to nuke all this code and have a single interface for parsing files sanely. The top level parser maps a file and emits a stream of lines. This should support comments, empty line elision and line continuations. Each line should come with a {{SourceLocation}} object for error messages. The stream of lines is consumed by a key=value tokenizer that each subsystem digests. This would be broadly similar to the {{GenericParser}} stuff.
