Bug 1125 - Make ELF Reader 'jogamp.common.os.elf' Stateless

ELF Reader 'jogamp.common.os.elf' currently uses
Platform's pre-determined OS_TYPE and CPUType.

It also uses the host platforms MachineDescription,
hence can not read ELF files from other machines.

This also forbids Platform to determine CPUType etc
w/o having a valid 'os.arch' property.

+++

ElfHeader should be split in
  - ElfHeaderPart1 (CPUType independent)
  - ElfHeaderPart2 (CPUType dependent)

Fix shall make the ELF Reader self containing
by only using ELF CPUType data, etc.

This requires customization of struct parsing,
where MachineDescription.Static index shall be
  - defined in ElfHeaderPart1 using e_Ident's CPUType.
  - used in ElfHeaderPart2 and all its struct types.
