Re-adding executable test by execution is required for 'blocker technology'
like Windows's 'Software Restriction Policies (SRP)',
which only gets activated by the actual execution attempt.
Merely testing the file's (ACL) execution flags via NIO's isExecutable is not sufficient.
Implementation first tests the file's (ACL) execution flags via NIO's isExecutable.
If the NIO test was successful or not available, the actual execution test is performed.
To mitigate the virus scanner's false positive, we use an executable shell script
per default now, which may be overriden by the new environment 'jogamp.gluegen.UseNativeExeFile=true'
Tested on GNU/Linux with one temp folder having mount options 'noexec'
and on Windows using Software Restriction Policies (SRP) disallowing one temp folder.
Both temp folder were first in line via environment 'java.io.tmpdir'.

java.nio.file.Files.isExecutable(Path)
Attempt to resolved virus scanner false positive detection on Windows
while deflating the native code test-exe file in the temporary folder.
As Julien Gouesse suggested, using Java 1.7's java.nio.file.Files.isExecutable(Path)
_may_ resolve the issue, this has to be thorougly tested.
This patch favors the nio's isExecutable file's ACL test
over the more intrusive execution itself using a simple shell script file w/ set executable flag.
Mind that previous tests allowed the shell script's execution,
even if the temp folder did not allow execution of native code.
We have to see how our testing results will be on this attempt.

testing executable of temp dir
This also avoids trying to unpack the test executable on Windows,
which may cause a virus scanner to halt the process or otherwise cause issues.

and 'searchSystemPathFirst' attributes
NativeLibrary can be instantiate by defining
'searchSystemPath' and 'searchSystemPathFirst' arguments,
allowing to specify the system path role while looking up the library.
Since NativeLibrary is utilized via DynamicLibraryBundleInfo upstream,
the latter interface shall allow users to specify those attributes.

+
+ - We shall also travers all interfaces upwards
+ - All methods and fields found upwards must be tested for compatibility as well!
+
+ Further:
+ - Add class-name to Field- and MethodInfo via new intermediate AbstractMemberInfo.
+ The class-name is used to have allow differs to find a class move upwards!

Uri to handle relative path
Fix IOUtil.cleanPathString(..) special case:
Special case '/a/./../b' -> '/b'
requires to resolve './' before '../'.
Allow IOUtil and Uri to handle relative path:
- IOUtil.getParentOf(..)
- IOUtil.cleanPathString(..)
Handle cases:
'a/./../b' -> 'b'
'.././b' -> '../b'
- Uri: Handle null scheme

caller to skip relative futile lookup
IOUtil.getResource(..) and IOUtil.ClassResources, needs more clarity.
ClassLoader shall be passed explicitly next to the optional
relative context Class instance.
This allows better efficiency, i.e. caller can pass ClassLoader
but skip a possible relative lookup, if not existing.

test-executable ; Use CustomInflate for Performance
- Use 'WinMain' for Windows test-executable
This may have little difference than using std 'main' entry
- Add Windows x86_64 test executable
Since the reporter claims the test executable works well
on Windows i386, maybe utilizing a x86_64 test executable
on same VM fixes the issue
- Use CustomInflate for Performance
- Skips GZIP header
- Adds own custom header [magic, deflate-size, inflate-size]
- Own header allows simplified I/O read and deflation

ensure launched native exe process terminates.
See Bug 1219 comment 58: It seems that on some Windows platforms
the launched native process using our test-exe keeps running
even though we issued Process.waitFor().
Hence we issue Process.destroy() in the finalize block
to at least attempt to terminate it.
Note: The Process implementation is platform specific and may vary.

hardcoded 'DEBUG_EXE_EXISTING_FILE = false'
This is required for security, i.e. not allowing to execute any pre-existing files!
In case we need to manually debug this issue,
we can re-enable it manually and locally, but not in public builds!

- Make StreamMonitor a daemon thread, i.e. not hindering VM from exit
- Earmark each InputStream's EOS state
and only attempt to readByte if !eos
- End loop and hence the thread if all InputStream
have reached EOS.
- Don't close the InputStream.
Closing the InputStream is expected to be done
by the owner, otherwise no EOS could even be reached!
- Flush the output PrintStream at thread exit

IOUtil.testDirExe():
- Satisfactory when executed
Failure to execute produce an IOException right at ProcessBuilder.start().
Hence we can allow an unexpected process exit value,
since we only want to learn whether executable files are allowed.
- More debug options
DEBUG_EXE: 'jogamp.debug.IOUtil.Exe'
DEBUG_EXE_NOSTREAM: 'jogamp.debug.IOUtil.Exe.NoStream'
- if DEBUG_EXE
- a pre-existing 'jogamp_exe_tst'+<SUFFIX> will be used as-is.
- the test-exe will not be deleted
- StreamMonitor is being used to dump stdout/stderr
if !DEBUG_EXE_NOSTREAM.

Previous test PE exe, commit 0ebc5398fa20d23214a37dc4930a1fa1617293c7,
was a console exe. A console exe opens a new console window
if not being launched from one.
New test PE exe is produced w/ '-mwindows', i.e. for Win32 API
w/o a console.

Windows using 'exe-windows-i586-268b.bin' (Fix attempt #1)
Replacing the tiny 268 byte sized 'exe-windows-i586-268b.bin' PE file
w/ a regular 2048 byte sized PE file 'exe-windows-i386-2048b.bin'.
File is produced via:
c:\mingw\bin\gcc -nodefaultlibs -nostdlib -s -Os -o tiny.exe tiny.c
Adding the 305 byte sized gzipped version 'exe-windows-i386-2048b.bin.305b.gz'
to the gluegen-rt jar file to reduce the payload for non Windows platforms.
Adding special property 'jogamp.debug.IOUtil.Exe' to debug testing the exe file,
enable via '-Djogamp.debug.IOUtil.Exe'.
Passes here on all Windows machines, however, the prev. one worked here as well.

- Use InterruptSource.Thread.create(..),
while reducing InterruptSource.Thread ctors to 3 variants.
- Use InterruptSource.Thread instead of java.lang.Thread where possible
- Use SourcedInterruptedException where possible
- SingletonInstanceServerSocket: start(), stop() and run()
- Persistent-Wait and Cancelable
- Add @since 2.3.2

implementation and semantics

- fix isInQueue(): condition was reverse in regars to 'isExecuted'
- expose 'Thread getExecutionThread()' as learned within run() method.
- RunnableTask
- deprecate: 'static invoke(final boolean waitUntilDone, final Runnable runnable)',
since it's nonsense, use runnable.run() instead.
- 'static RunnableTask invokeOnNewThread(..)'
- uses InterruptSource.Thread
- Persistent-Wait
- Cancelable using InterruptedRuntimeException
- FunctionTask
- deprecate 'static <U,V> U invoke(final boolean waitUntilDone, final Function<U,V> func, final V... args)',
since it's nonsense, use func.eval(args) instead.
- 'static FunctionTask<U,V> invokeOnNewThread(..)'
- uses InterruptSource.Thread

InterruptedRuntimeException
- InterruptSource interface declares methods to retrieve
the source of a Thread.interrupt() call.
- InterruptSource.Thread implements InterruptSource,
i.e. allows code running within such thread to learn about
the interrupt source (stack trace).
- SourcedInterruptedException is a InterruptedException specialization
which may include the source of the causing Thread.interrupt() call.
- InterruptedRuntimeException
An unchecked RuntimeException propagating an InterruptedException
where handling of the latter is not desired.
The causing InterruptedException may be of type SourcedInterruptedException,
hence a detailed stack trace analysis might be possible.

interrupts original-owner, even if not waiting at unlock()
RecursiveThreadGroupLockImpl01Unfairish.unlock():
An interrupt() is always issued
from group members on the original owner.
This shall only happen, if the original owner is waiting
within unlock() for all group members to be unlocked.
This extra interrupt causes side-effects, see Bug 1211.
Only issue the interrupt to wake-up the original owner
iff waiting within unlock!

RecursiveLockImpl01CompleteFair:
Issue 'Thread.interrupted()' to clear a slipped interrupt
call after while-loop.

Since all native libraries are now contained within 'natives/os.and.arch',
we don't need to search the whole JAR file anymore
but simply can copy the content of the defined folder - if existing.
