Introduce symbol versioning of the library

When creating a shared library, it is a good practice to associate version information to each exported symbol through LD version scripts: https://www.gnu.org/software/gnulib/manual/html_node/LD-Version-Scripts.html

While Meson doesn't have native support for it yet, there is a way to supply version scripts through cc.get_supported_link_arguments and link_with attribute in shared_library target. Examples are:

• https://github.com/p11-glue/p11-kit/blob/master/p11-kit/meson.build#L85
• https://github.com/hughsie/libgusb/blob/master/gusb/meson.build#L48
