Specify the soname in the library and its name
This provides users of this library the guarantee that the ABI will
stay stable when MAJOR will reach 1, and will stay backwards compatible
for the entire duration of the 1.x.y branch.
It does require the maintainers to always update the version in the
Makefile at every ABI change.
