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

https://jogamp.org/bugzilla/show_bug.cgi?id=681

+ * References:
+ * <ul>
+ *   <li>http://linux.die.net/man/5/elf</li>
+ *   <li>http://www.sco.com/developers/gabi/latest/contents.html</li>
+ *   <li>http://infocenter.arm.com/
+ *   <ul>
+ *      <li>ARM IHI 0044E, current through ABI release 2.09</li>
+ *      <li>ARM IHI 0045D, current through ABI release 2.09</li>
+ *   </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
