One macro that also defines the cleanup function, one macro that only
defines the unref. This is required for any place where we want to
use cleanup from multiple source files - like the test suite.
When called with NULL as the path to the EI socket, the function
ei_setup_backend_socket() will fallback to the LIBEI_SOCKET environment
variable to determine the path to the socket.
If that environment variable is not set, ei_setup_backend_socket() will
abort.
That means that an innocent client running in an environment without EI
support will be killed. If that client happens to be Xwayland, that would
abort the Xserver and take all X11 clients with it, including the window
manager itself in the case of mutter.
Return -ENOENT instead so that clients have a chance to recover and
survive the lack of EI support.

Building with a releaes build reshuffles things so this ends causing potential
issues. Initialize to NULL to avoid around this.

The logger utilities are useful for quick prototyping, but we've reached the
point where we need the "proper" implementation of a log handler.

Now that the backend is more of an implementation detail, namespace for
ei_setup_backend_foo()

The main reason for having different functions to create the initial context
was so we can nest the ei struct inside the context-specific struct. That
shouldn't leak into the API though and our use-case is probably one where we
create one context, then iterate through possible backends until one succeds -
having different contexts here doesn't help then.

This is the minimum framework to support connecting to a libeis server, adding
a device and sending relative pointer motion events.It's missing a bunch of
checks and verifications, many of the hooks are still missing, etc.
See the tools/ directory for an example. The protocol is as outlined in
commit f7a24b2fbd.
