So I think we should split the implementation in two:
1) Stop hardcoding LXCPATH in all the C code, instead make it default to
LXCPATH and overrideable by the set_lxc_path() call.
2) Discuss implementing a system wide, not container specific, lxc
configuration file to be used by all distros in a format that's easily
parsable.

Implementing 1) will make it easy for individual commands like lxc-list
to implement an extra argument letting the user override the lookup
path. It'll also make it much easier to deal with lxc being run as a
user at some point in the future.

Obviously, once we have that, some people will want to change the
default lookup location in one place and have all the commands use that
path. That's where we need 2) so that we can store that kind of settings
in a way that's not distro-specific and have all the tools in all the
different languages to parse that file.
