[libgpiod v2][PATCH v2 0/2] libgpiod v2: rewrite tests for the C library

[Bartosz Golaszewski <brgl@xxxxxxxx>]

This series contains a rework of the line_config interface and a bit patch
that replaces the old test suite for libgpiod v1 based on gpio-mockup with
a one covering around 95% of the libgpiod v2 code based on the upcoming
gpio-sim module.

v1 -> v2:
- drop applied patches
- improve documentation
- skip offsets that are overridden in line_config but not actually requested

Bartosz Golaszewski (2):
  line-config: expose the override logic to users
  tests: rewrite core C tests using libgpiosim
