[libgpiod][PATCH v4 00/20] Add support for bias flags and SET_CONFIG

[Kent Gibson <warthog618@xxxxxxxxx>]

 Changes v3 -> v4:
 - tests require kernel v5.5.0
 - use std::map for bias mappings in cxx bindings
 - drop gpiod_line_is_requested_values
 - various formatting and coding style fixes
 - relocate common tool code into tools-common
 - tools bail on bad command line parameters
 - add drive option to gpioset in a separate patch
 - split out documentation update for gpiod_line_set_value_bulk
 - split out change to vals variable in gpiod_Line_set_value

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:
