3fa396c012 test: add a framework for doing protocol tests directly 
This tests the protocol layer which is hard to test using libei/libeis.
Similar to the generated C bindings we compile a eiproto.py file that is
then used in the test to talk protocol directly to the eis-demo-server
that we start up.

By sending the specific messages and checking things happen as we expect
on the socket we can verify that the EIS implementation is correct (and
robust enough).

In theory this could also be used to test some other binary with an EIS
implementation and the scaffolding is there to set LIBEI_TEST_SERVER to
that binary. Wether this works is untested though...

d319c3a725 protocol: rename "type" arguments and events

those.

5f69ee2417 proto: switch to use the Wayland message header 
No real functional changes, this just changes the message header to be
header = [object_id, msglen << 16 | opcode].

The only difference to the wayland protocol is now the fixed vs float
but otherwise tools that can print/debug/mangle the wayland protocol
should be easily adjustable for this protocol too..

e67a0a7777 brei: add the brei_result object and bubble it up as error case 
Add a new simple object "brei_result" that maps to the protocol-type
reason + explanation. That object is now returned instead of the errno,
giving us better debugging options.

This changes the dispatcher functions from returning an int to returning
a brei_result instead (default NULL for success). A helper function for
converting a neg errno to a result is provided for convenience for now,
eventually all these paths should deal with things correctly.
