/proc/self/exe (Linux) or a found java/jvm native lib.
- PlatformPropsImpl.queryABITypeImpl: Check Elf Header for ARM + !ANDROID (i.e. add other OS than Linux, use native java/jmv lib)
- NativeLibrary.enumerateLibraryPaths: Add 'sun.boot.library.path' to enumeration!
- TestElfReader01: Add test for finding java/jvm native lib and parse it

Added self contained jogamp.common.os.elf package w/ entry point class ElfHeader
to read a RandomAccessFile and parse it as an ELF file.
ELF Parsing completness:
- Header: OK
- SectionHeader: OK
- Section Type SHT_ARM_ATTRIBUTES: OK
- Will be read into SectionArmAttributes
- Used to distinguisgh soft/hard VFP float
Tested manually on:
- Linux intel 32bit / 64bit, arm soft-float and hard-float

- NativeLibrary Fix
- enumerateLibraryPaths(..):
- Properly iterate through all prefix _and_ suffix.
- Make public for JNILibLoaderBase.loadLibraryInternal(..)
- isValidNativeLibraryName(..):
- Stop iterating through prefix, if previously found
but suffix doesn't match.
- JNILibLoaderBase.loadLibraryInternal(..) Enhancement
- Mark customLibLoader FIXME: remove (we will get rid of jnlp.launcher.class)
- If System.load(TempJarCache) and System.loadLibrary(plainLibName) fails,
use NativeLibrary.enumerateLibraryPaths() w/ System.load(..) as last resort.
Tested on Linux x86_64 Java6 and OSX Java7 manually, no regressions expected.

May break GCJ/ECJ .. needs to be revised.
- Adding JAVA_6 in PlatformPropsImpl
- Buffers.isDirect() chooses fast-path iff JAVA_6, otherwise using reflection (GCJ/ECJ)
- Adding JAVA_6 info in VersionUtil
- API doc: Refine JAVA_SE and JAVA_6 spec.
TODO: In case GCJ etc is unable to compile the JAVA_6 code
even though it uses a static condition (probably not),
We have to wrap isStatic in an own class, one for JAVA_6 and one for <= 1.5.
This will be a good exercise for further issues we may have w/ Java <= 1.5.

simple primitive stack implementation.
Currently only FILO put/get operations are implemented using either
primitive arrays as I/O itself or <Type>Buffer.
Unit tests are included..
Note: Only FloatStack is implemented in a manual, where others (IntegerStack)
is derived (generated) from it. Same goes w/ unit tests.

in case leading non digits appear.
'\D.*' matches a leading non-digit and then any character.
First the string is tokenized by delim:
"OpenGL ES GLSL ES 1.0.16" -> "OpenGL ES GLSL ES 1", "0", "16"
Enhance pattern as follows and access collected group if matching:
// group1: \D* == leading non digits, optional
// group2: \d* == digits
// group3: .* == any pending chars, optional
final java.util.regex.Pattern nonDigitsCutOff = java.util.regex.Pattern.compile("(\\D*)(\\d*)(.*)");
Reorganized storage from atomic values to int[3] array, allowing simple pattern matching loop.
Added unit test.

library loading
Some Platform field declarations and it's static initialization has been delegated
to it's new abstract super class PlatformPropsImpl to solve
static initialization interdependencies w/ the GlueGen native library loading
and it's derived information {@link #getMachineDescription()}, {@link #is32Bit()}, ..<br>
This mechanism is preferred in this case to avoid synchronization and locking
and allow better performance accessing the mentioned fields/methods.

'android-armv7hf' and 'linux-armv7hf' ]
- Platform gets new ABIType [ GENERIC, ARMEL, ARMHF ]
- Platform impl. needs to guess ABIType in case of ARM,
since no Java system property ('os.arch' ..) reflects the new EABI.
I consider this a bug, since this will also hinder JNLP to work.
The latter also uses 'os.arch' sys property to determine the nativelib resource!
(See Platform.guessABITypeImpl(..) for details how we guess the type.)

- Fix 'NIOOnly' impl
- Use 'final' in gen. Java stubs ;

- remove unsued vars/code
- Tests:
- covers normal/NIOOnly/NIODirectOnly
- covers passing null for array and NIO

Android ClassLoaderUtil cleanup;
- Add 'asset' URLConnection
- Please read API doc 'PiggybackURLConnection' and 'AssetURLConnection'
- Solves generic resource handling where platform locations may differ,
ie ClassLoader lookup on Android in the 'assets/' subfolder.
- New Android 'AssetDexClassLoader' uses 'assets/' folder for findResource(..)
- aapt.signed (our APK ant task)
- uses 'assets/' folder
- adds the 'assetsdir' attribute allowing to copy other assets into the APK
- IOUtil uses URLConnection / incr. effeciency
- using URLConnection on all getResource(..) since URL
is connected anyways for validation and URLConnection can be used by caller right away
- String getRelativeOf(URL, String) -> URL getRelativeOf(URL, String)
- preserves scheme, authority, etc
- simple parentOf handling, more efficient
- reusing new 'asset' protocol impl.
- Android ClassLoaderUtil cleanup;
- Use createClassLoader(..) impl for build-in static jogamp and user APKs,
which removes code redundancy
Tests: New code path, especially 'assets' are covered by new unit tests, no regressions on Linux.

An opaque type still needs to be converted to the right size (32/64 bit).
In case of a conversion, respect the pointer type.

'spawn off' process to become the lock owner.
To avoid complicated synchronization via synchronized, wait and notify between one thread
and a 'spawn' off thread which temporarly requires the hold lock,
RecursiveThreadGroupLock allows to add and remove other threads to become owners of the lock
as if they were the original holder.
This simplifies some rare locking use cases, eg. in JOGL's GLProfile initialization sequence
where a SharedResourceRunner thread is taking over initialization of shared resources.

com.jogamp.gluegen.cgram.types -> com.jogamp.gluegen.runtime.types
This is required for desired runtime memory layout.
- Split CompoundType to StructType + UnionType
- StructLayout:
- Utilizing SizeThunk alignment
- Alignment
1) Natural type alignment
2) Add Size
3) Trailing padding w/ largest element alignment
- Only perform memory layout once for type.
Status:
- Unit test passes w/ static MachineDescriptor64Bit
- FIXME static 32bit is faulty, uses 64bit size/alignment
- TODO runtime struct layout to please all platforms w/o worrying

- Preparation.
Currently GlueGen fails for type long (size) and some alignments (see package.html).
- The size and alignment values shall be queried at runtime.
- Compound alignment needs to follow the described natural alignment (also @runtime).
-
- Build
- add Linux Arm7 (EABI)
- junit test
- added compound/struct tests, pointing out the shortcomings of current impl.
- package.html
- Added alignment documentation
- remove intptr.cfg
- add GluGen types int8_t, int16_t, uint8_t, uint16_t
- move MachineDescription* into runtime
- Platform
- has runtime MachineDescription
- moved size, .. to MachineDescription
- use enums for OSType, CPUArch and CPUType defined by os.name/os.arch,
triggering exception if os/arch is not supported.
This avoids Java String comparison and conscious os/arch detection.
- MachineDescription:
- compile time instances MachineDescription32Bits, MachineDescription64Bits
- runtime queried instance MachineDescriptionRuntime
- correct size, alignment, page size, ..
