[PATCH libgpiod 0/7] build: detach the libgpiod API version from the libgpiod package version

[Bartosz Golaszewski <brgl@bgdev.pl>]

The versioning of libgpiod has become quite messy due to the rapid
evolution of the project in its initial stages (which forced an ABI
version change without bumping the API) and later extension with several
bindings and tools kept in the same repository.

Currently the library API version and the package version are the same
but we're at a stage where the core C API will most likely remain quite
stable but we're still extending other features of the project, like
the DBus API, tools and possibly other bindings. Bumping the C API
version because we added new features to included programs makes no
sense so this series proposes to detach the core C API version from the
libgpiod package version (except for the major version updates but I
don't expect there to be one anytime soon).

The core C API will also apply to C++ and GLib bindings as they track
the C API closely. Rust and Python bindings already have their own API
versions.
