startup, retrievable via getMonotonicStartupTime(). (performance)
Settings two long fields in getMonotonicTime() and creating Instant and using Duration
for high-frequency counter is too expensive.
currentTimeNanos() subtracts the startup time from the current monotonic time and returns the
resulting duration in nanoseconds, which lasts for 292 years since module startup.
This satisfies performance counter requirements.

(sec + nsec), currentTimeMillis() is also monotonic now, reused by Platform. Dropped Platform.currentTimeMicros()
Clock and its implementation was copied from jaulibs, a spin-off from Direct-BT.
The implementation uses `clock_gettime(CLOCK_MONOTONIC, &t)` and is considered safe and high-performant
as it avoids a kernel call via VDSO (GNU/Linux).

PlatformPropsImpl: Remove static OSXVersion and Version* vars, add JAVA_17 and JAVA_21 flag.
PlatformPropsImpl's static OSXVersion is JOGL specific and will be moved into its GLContextImpl.
PlatformPropsImpl's static Version are not required and eats up memory where it can be used transitionary.

back into Java
The generated JNI code JVMUtil_NewDirectByteBufferCopy(..)
calls Buffers.newDirectByteBuffer(..) and potential exceptions should be checked.

UnsafeUtil
UnsafeUtil centralizes the workarounds (hack) of certain Java>=9
modularization encapsulation pitfalls,
where no exports have been defined. The last resort.
1) Buffers utilizes UnsafeUtil for Java>=9 invokeCleaner.
2) To gain access for certain methods + fields w/o 'illegal access warnings',
we have to temporarily disable the IllegalAccessLogger.
Hence we provide a method 'T doWithoutIllegalAccessLogger(..<T> action)'
for our essential module access under Java >= 9.

@SupportedSourceVersion back to 11
Behold, the issue as documented at commit 2d89df89453c099d4e357aa17eae88efcf1d1b70,
one build machine failing to compile SourceVersion.RELEASE_11
was due to an incomplete installation of openjdk-11-jdk on Debian GNU/Linux. Wow.
I have re-installed the openjdk-11-jre and openjdk-11-jdk packages on said machine,
ensured they are being used .. and it works.
Another note here regarding usage of OpenJDK11 compile time environment
and Java8 target. If using Eclipse, I had to set the system runtime JDK to JDK 8.
Otherwise the 'editor clean-up' jobs would run against the JDK 11
classes and wrongly so change certain type castings etc, incompatible with Java 8.
If anybody knows a solution here .. shoot.

Document Java8 target constraints, i.e. where we need to set source, target and bootclasspath
to ensure target runtime Java8 compliance.
Fix one odd compile issue!
Using two theorethical identical GNU/Linux Debian 10 machines with same set of installed software,
one passes (like MacOS, Windows) and one fails.
The failure was due to the CStructAnnotationProcessor's @SupportedSourceVersion tag.
This downgrades the SourceVersion's previous bump from 6->11 (commit 610493b1724b5d91327f478338ff5d029bdcc032)
down to 8.
Interesting times ..

Test1p1Test1p1JavaEmitter
'com.jogamp.gluegen.test.junit.generation.Test1p1JavaEmitter' exposes a regression
using MingW64 8.1.0: System.loadLibrary() gives a "Can't find dependent libraries".
Here, 'Bindingtest1p1' is linked against 'test1' and fails to load
due to its wrong dependent library name within 'Bindingtest1p1'.
MingW64 8.1.0 dropped 'libtest1.so' into 'Bindingtest1p1.dll',
which is surely wrong. Even passing '-Wl,-soname=test1.dll' didn't help.
Note: Such constellation would only work with adding
the lib-path to PATH on Windows.
Since we don't utilize the method in any of our projects,
but use the dynamic library lookup method - this is not a blocker,
but wasted some good time.

As of Java9, sun.misc.Cleaner has moved to jdk.internal.ref.Cleaner.
However, access has been made (under the table) via sun.misc.Unsafe,
which we are using for now as we cannot set the jdk.internal.ref.Cleaner method accessible.
In this regard, we had to change our Cleaner.clean(..) method using a ByteBuffer
instead of a Buffer object paramter.
All tests have passed, no more illegal access case running on Java11 has been exposed.

When annotations were placed on dummy Java variables, the annotation
processor was emitting a RenameJavaType directive into the gluegen
config file that caused the emitted file to be named boolean.java
instead of RenderingConfig.java or Pixel.java. Turned off this behavior
when jname is given in the @CStruct annotation. I'm uncertain how much
this processor is even used, since I can't find any occurrences of
@CStruct outside the test code for it in gluegen.

libgluegen-rt[.so] -> libgluegen_rt[.so|.a]
Recognize Java9+ ..
- Recognize new Java9+ version string as of JEP 223
- Avoid Classpath's private findLibrary call
+++
Support JEP 178 static linkage (OpenJDK 1.8)
- Need to change native library basename: libgluegen-rt[.so] -> libgluegen_rt[.so|.a]
since the dash '-' is not supported in a ANSI-c function name.
- Added 'JNI_OnLoad_gluegen_rt' to recognize statical linked JNI code
- Added JNI_VERSION_1_8 to jni/jni.h

Current build system for JogAmp iOS Build is:

- Using own (still proprietary) OpenJDK 9 iOS Build
- OpenJDK 1.8 (This will be replaced by OpenJDK 11 soon)
- Xcode 10.2

Implementation currently uses 256 bit Secure Hash (SHA) algorithm, but this may change in the future.
Hence only use 'SHA' in the names, not 'SHA256'.

runtime validation
This change implements a strong SHA256 signature over:
1) source tree inclusive make recipe (SHA256-Source)
2) all class files (SHA256-Classes)
3) all native libraries (SHA256-Natives)
4) the class files as deployed in the jar (SHA256-Classes-this)
5) the native libraries as deployed in the jar (SHA256-Natives-this)
and drops all of these in the deployed Jar file.
This allows SHA256 validation of (4) + (5) at runtime
and further complete validation (1), (2) and (3) offline.
Full SCC would now required (1) - (3) to be placed on a server for further validation.
Optionally we may use GPG <https://gnupg.org/> or PGP to validate the build entity to implement the chain of trust <https://en.wikipedia.org/wiki/Chain_of_trust>
The SHA256 runtime validation is tested via: com.jogamp.common.util.TestVersionInfo
