PyModule_AddObjectRef() was added in cpython v3.10 while libgpiod claims
to depend on python v3.9. Replace it with an older variant that steals the
reference to the added object on success.

We're currently unintentionally exporting a bunch of symbols that should
remain local to sub-modules. Use __all__ where appropriate so that we
don't re-export standard library functions such as select() etc. in the
gpiod module.

Instead of telling the user what type this function returns (they can
check it by looking at the prototype), tell them what the return value
actually represents.

Python bindings now have their own setup.py script and can be built
separately from the rest of the code-base. Let's decouple the python
package version from libgpiod API (but let's keep a module attribute
containing the API version) by introducing a version.py submodule that
can be executed by the setup.py script. This way we have a single
canonical place defining the version number.

While we use it for edge event timestamps exclusively at the moment,
the actual enum names shouldn't limit its application and simply just
refer to existing clock types known by the GPIO uAPI. The relevant
functions are still called set/get_event_clock() as it's in line with
their functionality.

This commit is the result of a squash of all the commits created during
the development of libgpiod v2. This is done to preserve bisectability
of the git tree. It contains significant re-writes of the core C library
as well as C++ and python bindings. The tools have been adjusted to work
with the new API but have not undergone significant changes yet.
This commit contains the bulk of the work on libgpiod v2 but the
development continues with more changes planned.
