027f85e195 proto: switch connection_setup.version to mirror interface_version requests 
For most interfaces, the client announcing its supported version is
sufficient - the objects are all created server-side. For some
interfaces (ei_connection_setup and ei_callback right now) the client
needs to know the server-supported version.

So let's switch the current ei_connection_setup.version event (used to
negotiate ei_connection_setup's version) to a generic
`interface_version` event. This way our EIS implementation can
eventually send a version for ei_callback as well.

273eda39ca Move the C proto templates to the src directory 
These are very specific to libei/libeis, so let's not leave them
somewhere where they look like official bindings or something.

29cf354de6 scanner: drop the Target class, push to templates 
The Target was specific to libei/libeis, it resolved to "ei" or
"eis_client" depending on which component we were building. But that's
specific to our C implementation here, so let's push it into our C
implementation templates.

6ed610e30e Split the ping/pong request into its own interface 
Leave the ei_callback as-is and instead add ei_pingpong for the same
thing initiated by the server. The interface is otherwise identical but
for the direction it is supposed to flow.

This reduces the possibility of a client accidentally sending a
request when it is supposed to handle an event or vice versa.

f41cc91599 proto: add a ping/pong request 
This is effectively the same as connection.sync, but goes the other way.
This adds the ei_callback.done request.

In libeis this is (currently) enforced immediately after sending the
connection object. Not required there and makes the code a bit messier
but this way we can ensure that any client library handles that part of
the code.

8c85b8fc1f protocol: add ei_connection.invalid_object 
This event is to notify the client that an object used in a request was
unknown. This allows the client to work around race conditions like
binding to a seat that was removed.

This is currently the server-side only which is probably enough for now.
The only client-side created objects we have are the callbacks.

0a347f433f protocol: make the connection setup the zero object with a proper handover 
This changes the initial connection negotiation to have the
ei_connection_setup as the pre-existing object id 0. Once the client has
sent all the data to set up the connection, the EIS implementation
replies with a new object ID that is the ei_connection protocol object,
i.e. the main object.

This allows for version negotiation of our main protocol object.
