RecursiveLockImpl01Unfairish changes are in preparation of RecursiveGroupThreadLock.

- RecursiveLock _is_ interface.
- Use LockFactory to create a RecursiveLock.
- Impl: RecursiveLockImpl01Unfairish
- just using notify w/o any queue: fast
- still enqueuing new lock-applicants if queue full (nice)
- lock's sync extends AbstractOwnableSynchronizer and uses it (monitor)
- Impl: RecursiveLockImpl01CompleteFair
- using queue and interrupt for correctness (slow)
- lock's sync extends AbstractOwnableSynchronizer and uses it (monitor)
- Impl: RecursiveLockImplJava5 for using Java5's concurrency impl.
- to verify correctness, performance and deviation of locking time
TestRecursiveLock01 new performance measurements incl. simple avrg and deviation
shows best combined performance-deviation w/ our RecursiveLockImpl01Unfairish
os Linux and MacOSX.
RecursiveLockImpl01Unfairish is the default in LockFactory.
Adding 'private' LockDebugUtil, allowing validating all holdings locks
of one thread as stack traces (Throwable).
Besides the AbstractOwnableSynchronizer utilization, this helps debugging deadlocks
and starvation very well.

TempJarCache.bootstrapNativeLib(..) usage
- Moving to Platform solves former interdependencies between GlueGenJNILibLoader/Platform
- TempJarCache is being setup w/ bootstraping the gluegen-rt native lib jar file.
Interesting here is that when using Oracle's JRE w/ Applets/JNLP the
current dbg output is:
gluegen-rt: url-root http://risa/deployment/test/jau02s/jar/
gluegen-rt: nativeJarURL jar:http://risa/deployment/test/jau02s/jar/gluegen-rt-natives-linux-amd64.jar!/
gluegen-rt: nativeJar /home/sven/.java/deployment/cache/6.0/49/3c6d1e31-2c90f42e
IE the JRE implementation already deduces the online link to the Applet/JNLP cache.
This makes the implementation much simpler, ie. same for application and Applets/JNLP.
Have to verify w/ other Java impl. sure - and add same logic for the JOGL part.

gluegen-rt native lib as well
- removed redundance
- move proper JNLPAppletLauncher custom libloader code into JNILibLoaderBase
- prepares for new JAR temp cache ..
|
| |
|
|
|
|

setting will be changed in JOGL as well

GluegenVersionActivity uses ApplicationContext
Hide DynamicLinker impl.:
- com.jogamp.common.os.*DynamicLinkerImpl -> jogamp.common.os

- build:
- exclude android packages if !isAndroid
- aapt:
- Use individual AndroidManifest xml files
- optional: incl. our JAR manifest file to support detailed version info
- use def. GluegenVersionActivity
- APK VersionName: Retrieve and show
- package/extension names:
- gluegen.jar/apk: com.jogamp.gluegen
- gluegen-rt.jar/apk: com.jogamp.common

- android minor build fix
- started dex'ing (gluegen-rt.apk, more to come for full junit tests)
- android remote dalvikvm launch works (crosstest-java-android-armv7-rel.sh)
- android detection, incl version (reflection)
- Platform:
- Add JAVA_VM_NAME and JAVA_VM_RUNIME
- OSType maybe ANDROID, where the OS name (String) is Linux ! (ok ?)

- Fin
MachineDesction == MD
MD.StaticConfig:
- enum for all supported static configs (ID -> MD)
- verified at runtime: test runtime queried-MD versus static-MD,
hard fail if not compatible (size/alignment)
SizeThunk primitive sizes:
- Add notion of fixed native size (eg. int64_t) and otherwise (eg. long)
java struct 'wrappers' code generation:
- single class using size/offset arrays of all MachineDescription configurations
- at runtime the array idx is queried in static block
- type aligment for not fixed-native-size types (SizeThunk, undef long/int) via StructAccessor
junit test:
- add float test
- fix native code
- add java (create, write) -> native (verify) test
works (tested) on: linux 32/64 and windows 32/64

Platform:
- enum CPUFamily is part of CPUType
- DALVIK -> ANDROID
- ARM: ARM + ARMv[567]
MachineDescription
- self contained
- static size/alignment Config (enum) for unix32, unix64, win32, win64 and armeabi
- add 'long double'
- Removed MachineDescription32Bit, MachineDescription64Bit
- createStatic(..) uses OS/CPU to fetch best match if not at runtime
FIXES: JavaEmitter's struct-emit: Proper 32/64 struct sizes
TODO: StructAccessor's mapping to <Type>Buffer w/ index os sizeof(<Type>)
doesn't work, since offset may not be multiple of sizeof(<Type>)!
i.e.
typedef struct {
int8_t bits1; // +1 - 0
// +3 (p32)
int32_t id; // +4 - 4
int8_t bits2; // +1 - 8
// +3 (p32) -
int64_t long0; // +8 - 12
so "longBuffer.get(<type-sized index>)" is invalid,
but "byteBuffer.getLong(<byte index>)" must be done.
The actual impl. doesn't matter, hence dropping the other nio type mappings is good.

- SizeThunk
- rename: compute -> computeSize
- add: computeAlignment
- merge types: char -> int8, short -> int16
- 'int' and 'long' may differ

Fix commit f733203dfbd034a6b1aa3eb2cd616437c982c435,

- 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, ..

moved up)
We learned that FileChannel.lock() is not reliable on at least GNU/Linux + Sun's JVM implementation,
hence we need a ServerSocket implementation.
Since this code may be useful to others, it has been promoted to GlueGen.
- Abstract SingletonInstance
- Implement Lock interface
- SingletonInstance Spezialisation: FileLock and ServerSocket
Minor API Change: LockExt.isLocked() -> Lock.isLocked()

jogamp.<module>
- com.jogamp.common.impl -> jogamp.common
This sorts implementation details from the top level, ie skipping the public 'com',
allowing a better seperation of public classes and implementation details
and also reduces strings.
This approach of public/private seperation is also used in the OpenJDK.
