libgpiod: update to v2.3

Starting with this release, libgpiod now uses meson so the updates to
the recipe are quite extensive. There's a new shared library:
libgpiotools, that exports symbols previously only accessible to
gpio-tools that allow users to build their own high-level programs while
reusing the code doing GPIO line & chip lookup. While at it: move
libgpiodbus into its own package as well.

Full changelog:

New features:
- replace autotools with meson & ninja as the build system
- provide libgpiotools: a new shared library exposing a public API for
  line name lookup and other high-level helpers previously only available
  internally to gpio-tools
- add initial-state option to gpiomon to display line states before
  waiting for events
- provide comprehensive sphinx-based documentation for all components:
  core C API, C++ bindings, Python bindings, GLib bindings, D-Bus API,
  gpio-tools, and libgpiotools
- extend libgpiosim with new routines allowing to use the new functionality
  provided in more recent versions of the gpio-sim module in the kernel

Improvements:
- make tests work with newer coreutils by removing cases checking tools'
  behavior on SIGINT which stopped working due to changes in behavior of the
  timeout tool
- decouple the libgpiod core C library API version from the global libgpiod
  project version as the former is now quite stable and no longer changes
  with every release
- extend libgpiosim self-tests

Bug fixes:
- allow modifying settings for existing offsets in a full line-config
- fix signed/unsigned type mismatch in gpiod_line_request_get_value()
- add explicit NUL-termination after strncpy() calls in core library
- fix consumer string in line_info stream operator in C++ bindings
- use get_mapped_value() for all enum mappings in line_info in C++ bindings
- move g_tree_remove() out of g_assert() in gpiodbus_id_free() to avoid
  resource exhaustion when assertions are disabled
- return 0 when zero events are requested in edge-event API
- fix gpionotify watching lines on the wrong chip
- reject trailing garbage in parse_period() in gpio-tools
- store interactive sleep period in a long long in gpioset to avoid overflow
- use gpiod_line_settings_free() to release settings in line-config
- fix buffer over-read bugs when translating uAPI structs to library types
- fix variable and argument types where necessary
- sanitize values returned by the kernel to avoid potential buffer overflows
- fix memory leaks in gpio-tools
- add missing return value checks in gpio-tools
- fix period parsing in gpio-tools
- use correct loop counter in error path in gpio-manager
- don't try to export the same chip object twice in gpio-manager on duplicate
  uevents
- use the "add"/"remove" uevents when watching for GPIO chips in the system as
  the "bind"/"unbind" pair is only emitted by linux for controllers which don't
  have a firmware node attached
- don't allow clearing hogs on active devices in tests
- don't install uneeded files
- fix a pkgconfig check in configure
- fix a return type check in test harness
- don't implicity unquote unnamed lines in gpioinfo
- remove useless variable in reconfigure example
- don't let struct line_config balloon out of control and trigger an OOM
- drop python3-config check from configure.ac
- fix potential PyDict_Next() crash in python bindings
- disable the GPIO simulator before releasing it in C++, rust and python
  bindings tests
- fix the way we wait for simulated chips to appear in D-Bus command-line
  client tests
- make read_edge_events lifetimes more explicit in rust bindings
- make waiting for info events more reliable in GLib bindings tests
- defer removal of bank entries when device is not disabled in libgpiosim
- add missing LineInfo import to __init__.py in python bindings
