* Add Makefile dependency to source file
* Add argument support
* Add help support
* Print usage on wrong arguments
* Add support for parsing VBT binary file
* Add support for parsing PCI Option ROM
* Add support for writing VBT binary file
* Add support for patching PCI Option ROM
* Keep support for accessing legacy VGA area Option ROM
* Keep support for dumping VBT contents to stdout

Allows to extract VBT, analyse VBT and patch PCI Option ROMs as needed.

The required arguments have been changed:

./intelvbttool --<SOURCECMD> [filename] --<DESTCMD> [filename]

SOURCECMD set the VBT source. Supported:
 inlegacy  : Legacy BIOS area at phys. memory 0xc0000
 invbt     : Read raw Intel VBT file

DESTCMD set the VBT destination. Supported:

Any combination of SOURCECMD and DESTCMD is possible.
