libxkbcommon: update to 1.3.0.

libxkbcommon 1.3.0 - 2021-05-01
==================

- Change `xkbcli list` to output YAML, instead of the previous ad-hoc format.

  This allows to more easily process the information in a programmetic way, for
  example

    xkbcli list | yq -r ".layouts[].layout"

  Contributed by Peter Hutterer.

- Optimize a certain part of keymap compilation (atom interning).

- Fix segmentation fault in case-insensitive `xkb_keysym_from_name` for certain
  values like the empty string.

  Contributed by Isaac Freund.

- Support building libxkbcommon as a meson subproject.

  Contributed by Adrian Perez de Castro.

- Add `ftruncate` fallback for `posix_fallocate` in `xkbcli interactive-wayland`
  for FreeBSD.

  Contributed by Evgeniy Khramtsov.

- Properly export library symbols in MSVC.
