[libgpiod v2][PATCH v3 0/4] bindings: implement python bindings for libgpiod v2

[Bartosz Golaszewski <brgl@xxxxxxxx>]

This is the third iteration of python bindings for libgpiod but it really has
very little in common with the previous version.

This time the code has been split into high-level python and low-level
C layers with the latter only doing the bare minimum.

The data model is mostly based on the C++ one with the main difference
being utilizing dynamic typing and keyword arguments in place of the
builder pattern. That allows us to reduce the number of methods and
objects.

Because python doesn't have RAII, unlike C++, we provide a module-level
request_lines() helper as gpiod.Chip(path).request_lines(...) one-liner
could lead to the chip left dangling even after the last reference is
dropped.

Because python forces us to dynamically allocate objects all the time even
for fundamental types (which are also immutable) there's no point in trying
to replicate the edge-event buffer. Instead LineRequest.read_edge_event()
just returns a list of events.
