[jdk8u-dev] RFR: 8193017: Import freetype sources into OpenJDK source tree

[Jiří Vaněk]

Hi!

I had recently hit an issue with jdk8, which, if build on old system - eg el7, it can not run GUI application on newest system like f42 or similar:

java.lang.UnsatisfiedLinkError: /usr/lib/jvm/java-1.8.0-openjdk-jdk8u462.b05-0.ojdk8~u~upstream.hotspot.release.sdk.el7.x86_64.tarxz/jre/lib/amd64/libfontmanager.so: /lib64/libharfbuzz.so.0: undefined symbol: FT_Get_Color_Glyph_Layer

As per investigations the issue is in duality of freetype, and is solved by `8193017: Import freetype sources into OpenJDK source tree`

This is fully based on unfinished https://github.com/openjdk/jdk8u-dev/pull/318 , with smal lexception of rebase, and docs adaptation.  The change in `doc/building.html ` is unluckily done manually, as `make update-build-docs` is regenerating half of the universum. Is it desired?  Is there some recomended version of pandoc to use?

 pandoc --version
pandoc 3.1.11.1
Features: +server +lua
Scripting engine: Lua 5.4


I had tested builds on windows and several linuxes, run full jtregs and checked the GUI works again. I can link full set of tests if needed (actually many of them are still running).

For record, I built by temurin build wrapper, which needed an change to adapt to this: https://github.com/adoptium/temurin-build/pull/4287
