[libgpiod] [PATCH 00/19] Add support for bias flags and SET_CONFIG

[Kent Gibson <warthog618@xxxxxxxxx>]

This patch series adds support for changes to the GPIO uAPI that are on
track to be included in the v5.5 kernel.  There are two components to the
uAPI changes - the addition of bias flags and a new SET_CONFIG ioctl.  This
series adds support to the libgpiod API, and to both C++ and Python
bindings, for both of those components.

The libgpiod tools are also updated, where appropriate, to support the bias
flags.

There are a few additional patches that serve to restructure the code to
simplify subsequent patches, or to fix minor problems discovered during
development. These patches are generally adjacent to the main patch most
relevant to that patch.

The series is based on the current libgpiod master@9ed02fc.
