cbfstool: Rework to use getopt style parameters

Browse Source 
- Adding more and more optional and non-optional parameters
  bloated cbfstool and made the code hard to read with a lot
  of parsing in the actual cbfs handling functions. This change
  switches over to use getopt style options for everything but
  command and cbfs file name.
- This allows us to simplify the coreboot Makefiles a bit
- Also, add guards to include files
- Fix some 80+ character lines
- Add more detailed error reporting
- Free memory we're allocating
