Some of the unit tests intentionally call methods or assign properties
with invalid values to ensure they fail in an expected way.
Type checkers complain for these instances so inform them via directive
that these lines should be ignore for specific errors.
Additionally, some lines that access properties without assigning the
value look like they perform no action to linters.
To appease the linter, read the value into a throw-away variable.

Add type hints for internal members of the test cases so type checkers
can ensure the code properly constrains to these types and accounts for
scenarios where the values are `None`.
In most cases, the type checker is allowed to assume the inferred type
upon assignment.
An example is any test case that creates a `Chip` as part of its `setUp`
method. Many of these tests subsequently set the reference to `None` in
`tearDown` to free up resources to be collected by the GC.
If the member was "properly" typed to be `Optional`, all references in
the unit tests would need to be guarded by an assert or a cast or
ignored by the type checker. This is noisy and doesn't add value since
for the life of the test it should always be a valid reference.
Instead, allow `tearDown` to violate the inferred type and inform the
type checker to ignore the assignment via directive.
If the tests are ever changed to set the member to something other than
the inferred type outside of `tearDown`, explicit type hints and proper
checks should be added.

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.
