[libgpiod v2][PATCH v4 0/2] libgpiod v2: rewrite tests for the C library

[Bartosz Golaszewski <brgl@xxxxxxxx>]

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

v2 -> v3:
- add a patch adding an enum for line values
- rework the mechanism for retrieving overrides
- add new "constructors" for line_config
- incorporate part of Kent's points in the documentation
- a bunch of improvements to tests as per Kent's reviews

v3 -> v4:
- drop the new constructors added in v3
- improve the docs for override interfaces
- use NUM_OVERRIDES_MAX when referring to the max number of overrides

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