[jdk11u-dev] RFR: 8255790: GTKL&F: Java 16 crashes on initialising GTKL&F on Manjaro Linux

[Severin Gehwolf]

Please review this backport of JDK-8255790 which fixes a crash of simple FileDialog-using apps on some systems (for example F34 when not using system harfbuzz). See JDK-8272149. In a nutshell, this patch is a not quite complete revert of JDK-8249821. I.e. the OpenJDK 11u version of it. It does not revert the source code re-structuring, though. The JDK 17 patch doesn't apply clean. I've mostly hand-picked changes from the original patch. Note that JDK-8272332 is included in this backport. The differences mostly stem from differences in DISABLED_WARNINGS_ settings when BUILD_FONTMANAGER is being called.

Testing: Build on an affected system with/without --with-harfbuzz=system. Reproducer from JDK-8272149 (crashes before, passes after)
