platforminputcontexts: use libxkbcommon compose key API Our implementation of compose table parser was added on Mar, 2013. libxkbcommon added APIs for the same thing in Oct, 2014 (ver: 0.5.0). After removing RHEL 6.6 from the list of supported platforms we were able to move the minimal required libxkbcommon version to 0.5.0. Now we can use the xkbcommon-compose APIs on all supported platforms. With this patch we can drop nearly 1000 lines of maintenance burden. This patch fixes user reported issues with our implementation. Known issues: - Testing revealed that xkbcommon-compose does not support non-utf8 locales, and that is by design - https://github.com/xkbcommon/libxkbcommon/issues/76 Our implementation did work for those locales too, but it is unclear if anyone actually uses non-utf8 locales. It is a corner case (work-arounds existing) and likely a configuration error on the users' system. - Looking at the release notes for versions above 0.6.1, only one issue that stands out. Compose input does not work on system with tr_TR.UTF-8 locale, fixed in 0.7.1. Compose input works fine when using e.g. en_US.UTF-8 locale with Turkish keyboard layout. Note: With Qt 5.13 we have removed Ubuntu 16.04 and openSUSE 42.3 from CI: Ubuntu 16.04 - 0.5.0 openSUSE 42.3 - 0.6.1 CI for Qt 5.13 has: Ubuntu 18.04 - 0.8.0 RHEL-7.4 - 0.7.1 openSUSE 15.0 - 0.8.1 Currently the minimal required libxkbcommon version in src/gui/configure.json is set to 0.5.0, but we could bump it to 0.7.1 to avoid known issues from above, but that is a decision for a separate patch. [ChangeLog][plugins][platforminputcontexts] Now using libxkbcommon-compose APIs for compose key input, instead of Qt's own implementation. Fixes: QTBUG-42181 Fixes: QTBUG-53663 Fixes: QTBUG-48657 Change-Id: I79aafe2bc601293844066e7e5f5eddd3719c6bba Reviewed-by: Giulio Camuffo <giulio.camuffo@kdab.com> Reviewed-by: Johan Helsing <johan.helsing@qt.io>
