Generalize the IO client handling in Luxi
... to be usable for WConfd as well. A daemon handler is encapsulatedinto `Handler` data type, which is then passed to a generic `listener`.
The changes are done in Luxi.hs so that the differences are visible and...
Generalize "validateCall" to be usable outside LUXI
Return the method (as any instance of JSON) and the arguments of a call.
Add the Unix domain socket path to the Server data type
This simplifies code for closing such a socket.
Encapsulate a server socket and its parameters
Instead of passing a bare server socket around, we pass it encapsulatedin a data type together with parameters such as read/write timeouts.
Rename getClient/Server to getLuxiClient/Server
Later they will be split into LUXI-specific and general parts.
Split Luxi.hs into LUXI-specific functions and general ones
This will allow WConfD to use the general functions without importingLuxi.hs.
