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.
