Distribute versioned shared libraries

[edubart]

Context

Currently an application that was linked to a newer libcartesi.so version such as v0.14.0 is able to run on systems with old emulators version such as v0.13.0 and potentially crash because of mismatches in the C ABI interface. This is because the shared library always has the name cartesi.so, and there is no option to link to a versioned shared library.

This is also a problem in an environment where different emulator versions coexist in different paths, a typical situation when developing a new emulator while having to test an old emulator.

Possible solutions

We should start distributing a versioned shared library, such as libcartesi.so.0.14.0 and make libcartesi.so a symlink to it.
This way we can link programs to versioned shared libraries, and then attempts to run an application that was actually linked to a different emulator will give an error about the shared library not found instead of a crash or undefined behavior. We should also make use of this, that is, start to link a versioned library for cartesi.so.
