lib: Introduce versioned symbols
As rpm-ostree evolves, it keeps driving API additions to libostree. This creates a relatively tight coupling. However, if delivering via e.g. RPM, unless one manually remembers to increment the `Requires:` in the spec file, it's possible for the two to become desynchronized. RPM handles versioned symbols and will ensure a dependency if the application starts using a newer version. To implement this, switch to `-fvisibility=hidden`, along with an annotation in the header, and finally add a `.sym` file. This matches what other projects like systemd and libvirt do. Although rather than attempting to retroactively version symbols, glom them all onto the current one.
