Change in ...coreboot[master]: cbfstool: Add ifittool

[Patrick Rudolph (Code Review)]

Hello Aaron Durbin, Julius Werner, Subrata Banik, Duncan Laurie, build bot (Jenkins), Kai Michaelis, Patrick Georgi, Furquan Shaikh, Amol N Sukerkar, Roy Wen, David Hendricks, Philipp Deppenwiese, Nico Huber, Martin Roth, Jens Drenhaus,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/31493

to look at the new patch set (#14).

Change subject: cbfstool: Add ifittool
......................................................................

cbfstool: Add ifittool

Add the IntelFirmwareInterfaceTable-tool to modify the FIT.
As cbfstool is overloaded with arguments, introduce a new tool
to only modify FIT, which brings it's own command line syntax.

Provide clean interface to:
* Clear FIT
* Add entry to CBFS file
* Add entry to REGION
* Delete entries
* Add support for types other than 1
* Add support to dump current table
* Add support for top-swap
* Sort entries by type

Most code is reused from existing cbfstool and functionality of cbfstool
is kept. It will be removed once the make system uses only ifittool.

Based on "Intel Trusted Execution Technology (Intel TXT) LAB Handout"
and https://github.com/slimbootloader/slimbootloader .
