[libgpiod][PATCH 0/6] treewide: another bunch of cleanups for v2.0

[Bartosz Golaszewski <brgl@xxxxxxxx>]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

Kent suggested I send the patches for v2.0 API in smaller batches for earlier
review instead of dropping a huge patch bomb that will require more work from
my side and may later be negatively reviewed so here's a hopefully the last
part of cleanups that can go into master already before first patches with the
new C API will drop.

The idea for the new C API is this: all objects are opaque and refcounted. This
is why the chip was converted to reference counting. Lines were removed and
their functionality split into line_info and line_request, this is why I'm
reworking line lookup to return the HW offset within a chip and not the line
object. Other patches are mostly cleanups and cruft shave-off.

Bartosz Golaszewski (6):
  treewide: simplify line lookup
  tests: remove line bulk test cases
  core: switch to reference counting for gpio chip objects
  treewide: remove is_requested() and is_free()
  treewide: kill line updating
  core: hide the GPIOD_API symbol
