GetPrimitiveArrayCritical(..)
The 'carray' pointer returned from GetPrimitiveArrayCritical(..) was moved about the array offset
and used in ReleasePrimitiveArrayCritical(..) to release the pinpointed memory.
Even though this 'is' a bug by violating the _sparse_ specification, Hotspot impl. doesn't use the value at all (NOP)
and hence this code didn't produce an error since .. (Same w/ Dalvik).
Now the array offset is added while passing the carray pointer to the native function call
and hence is no more modified and the orig. value is passed to ReleasePrimitiveArrayCritical(..).
Tested w/ GlueGen unit tests and all JOGL unit tests (on Linux x64 w/ 'a' hotspot VM).

- Fix 'NIOOnly' impl
- Use 'final' in gen. Java stubs ;
- No null check for Buffers.isDirect(arrayArg) [required]
- Clarify Buffer arg API doc (NIOOnly or NIODirectOnly)
- cleaned up loop / branch (CMethodBindingEmitter)
- remove unsued vars/code
- Tests:
- covers normal/NIOOnly/NIODirectOnly
- covers passing null for array and NIO

const, ie no write-back
We shall consider the C header declaration as being correct
and no modification shall happen on const arrays.
Tested w/ unit tests and JOGL

Reversed Type relocation (commit 92d6c9dc5fa72b01703456452c60822f36c14fff)
from com.jogamp.gluegen.runtime.types back to com.jogamp.gluegen.cgram.types
Enabled MemoryLayoutType.setLayouted(), avoiding double layout

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, ..
