[libgpiod][PATCH v3 00/14] Add support for bias flags and SET_CONFIG

[Kent Gibson <warthog618@gmail.com>]

Changes v2 -> v3:
 - rebase on core: deprecate gpiod_needs_update()
 - rework needs_update related logic in core: add support for SET_CONFIG

Changes v1 -> v2:
 - address all v1 review comments
 - tools accept bias flag field rather than individual flags
 - add tests for tool changes
 
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.

The series is based on the current libgpiod master:
 master@2964441 core: deprecate gpiod_needs_update()
