Bug 681: Add Basic ELF Header + ARM EABI Section Parsing, allowing to distinguish ARM soft-float/hard-float (part-1)

+ *   </ul></li>

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
