The ABI of a shared library on Linux is given by a major version, which is part of the SONAME and is incremented (rarely) on incompatible changes, and a minor version, which is part of the basename of the regular file to which the SONAME provides a symlink. Until now, the ABI minor version was hard-coded, which means we can't tell which of a pair of Wayland libraries is newer (and therefore likely to have more symbols and/or fewer bugs). libwayland-egl already had ABI major version 1, so we can use the "marketing" version number as the ABI major.minor version number directly, so Wayland 1.19.90 would produce libwayland-egl.so.1 -> libwayland-egl.so.1.19.90. libwayland-cursor and libwayland-server have ABI major version 0, and OS distributions don't like it when there's a SONAME bump for no good reason, so use their existing ABI major version together with the "marketing" minor version: libwayland-cursor.so.0 -> libwayland-cursor.so.0.19.90. If the Wayland major version number is incremented to 2, we'll have to rethink this, so add some error() to break the build if/when that happens. Assuming that Wayland 2.0 would involve breaking changes, the best way would probably to bump all the SONAMEs to libwayland-foo.so.2.
