GlueGen proper size / alignment of primitive and compound types usage [1/2] - 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, ..
