Currently both libwayland-client and libwayland-server contain the core protocol symbols. This disappoints ASAN when both libraries are included in the same binary (such as in our test suite).
Compositors also can include both client and server libraries, so this provides some pointless minor space savings in real world usage as well.
Let's split the protocol bits off into their own library to avoid this duplication.
