This is mostly in preparation for the win32 port, which won't use GIO channels for reasons that will be made clearer later. Here the GAChannel class is just a loose wrapper around GIOChannel calls/callbacks, but we also roll in the logic/configuration for various channel types and managing unix socket connections, which makes the abstraction much more complete and further aids in the win32 port since isa-serial/unix-listen will not be supported initially. There's also a bit of refactoring in the main logic to consolidate the exit paths so we can do common cleanup for things like pid files, which weren't always cleaned up previously.
