69e6eb5a89 accept attr args to pppoe service, and typecheck them 
We use (abuse, arguably) the nixos module system for typechecking.  Un
the plus side, it gives us documentation of the options and their
expected types. On the downside, the error message doesn't tell us
the file in which the error was encountered.

(This is subject to change, if I can find a better way)

9441f48819 new ppp module, used by rotuer 
The objective here is that services which depend on global config
(e.g. kernel config or busybox options or static paths in the
filesystem) now live under config.system.service, and are added
to that collection by the module that defines the necessary state.

This is a first step: the services will be configured by a typechecked
attr set instead of the arbitrary arguments that
pkgs.liminix.networking.pppoe accepts

2e50368bd2 rename config.outputs to config.system.outputs 
New rules: everything under "config" that isn't actually configuration
(e.g. build products) will in future live in config.system. This is
the first step.

3900683413 simplify protocol for watchers of service output directories 
Previously: the service wrote a timestamp and the receiver
read and parsed it to see if there was new data

Now: the service writes and removes a .lock file to prevent
the receiver reading partial data. The receiver is responsible
for remembering the *previous* state and only updating if it's changed
