libxkbcommon: upgrade 1.6.0 -> 1.7.0

Changelog:
===========
- Added early detection of invalid encodings and BOM for keymaps, rules & Compose.
  Also added a hint that the expected encoding must be UTF-8 compatible.
- Updated keysyms using latest [xorgproto]
- Keysyms: Fixed inconsistent results in 'xkb_keysym_from_name' when used with
  the flag 'XKB_KEYSYM_CASE_INSENSITIVE'.
- Keysyms: Fixed case mapping for 3 Latin 1 keysyms:
  - 'XKB_KEY_ydiaeresis'
  - 'XKB_KEY_mu'
  - 'XKB_KEY_ssharp'
- Keysyms: Fixed 'xkb_keysym_is_modifier' to detect also the following keysyms:
  - 'XKB_KEY_ISO_Level5_Shift'
  - 'XKB_KEY_ISO_Level5_Latch'
  - 'XKB_KEY_ISO_Level5_Lock'
- Prevent recursive includes of keymap components.
- Fixed global default statements 'x.y = z;' in wrong scope not raising an error.
- Rules: Made newline required after '!include' line.
- Rules: Fixed a bug where variant indexes were ignored with the layout index
  used instead. They are practically always the same, but don't have to be.
- Compose: Fixed a segfault with 'xkb_compose_table_iterator_next' when used on an
  empty table.
- Compose: Added check to ensure to open only regular files, not e.g. directories.
- Registry: Updated the DTD and always parse the "popularity" attribute.
- Fixed a few memory leaks and keymap symbols parsing.
