aubinator: Add a new tool called Aubinator to the src/intel/tools folder.

The Aubinator tool is designed to help the driver developers in debugging
the driver functionality by decoding the data in the .aub files.
Primary Authors of this tool are Damien Lespiau <damien.lespiau at intel.com>
and Kristian Høgsberg Kristensen <krh at bitplanet.net>.

v2: Review comments are incorporated by Sirisha Gandikota as below:
1) Make Makefile.am more crisp, reuse intel_aub.h from libdrm (per Emil)
2) Aubinator will use platform name instead of GEN number (per Matt)
3) Disassmebler gets created based on pciid rather then GEN number (per Matt)
4) Other formatting comments (per Ken, Matt and Emil)
