We used to disable individual warnings that are expected when building
our GCC version with a newer one. Not all warnings can be disabled
indvidually, though, and it's much easier to simply allow warnings.
As a plus, we get the warnings in the log (in case anybody would ever
look into it).
Partially fixes building with host GCC 12.1.

This patch adds a new line to `cbfstool print -v` output that records
the overall CBFS verification health of the image. While this info was
already visible from individual fields before, it's nice to have a
one-stop location to see "this is a good image" without having to
carefully parse a lot of output manually.
Also add a few lines to the Makefile that check whether this field is
valid for the final image (it always should be, but hopefully this check
will allow us to catch regressions like the one fixed by CB:64547 sooner
in the future).

so align its output with that of other tools used there:
- Replace "Original-Commit-Id" with "GitOrigin-RevId"
- Reuse Change-Id instead of moving it to the Original- prefix, which
leads to the creation of a new Change ID.

The Intel Firmware Interface Table (FIT) is a bit of an annoying outlier
among CBFS files because it gets manipulated by a separate utility
(ifittool) after cbfstool has already added it to the image. This will
break file hashes created for CBFS verification.
This is not actually a problem when booting, since coreboot never
actually loads the FIT from CBFS -- instead, it's only in the image for
use by platform-specific mechanisms that run before coreboot's
bootblock. But having an invalid file hash in the CBFS image is
confusing when you want to verify that the image is correctly built for
verification.
This patch adds a new CBFS file type "intel_fit" which is only used for
the intel_fit (and intel_fit_ts, if applicable) file containing the FIT.
cbfstool will avoid generating and verifying file hashes for this type,
like it already does for the "bootblock" and "cbfs header" types. (Note
that this means that any attempt to use the CBFS API to actually access
this file from coreboot will result in a verification error when CBFS
verification is enabled.)

There are too many "FIT" in firmware land. In order to reduce possible
confusion of CBFS_TYPE_FIT with the Intel Firmware Interface Table, this
patch renames it to CBFS_TYPE_FIT_PAYLOAD (including the cbfstool

Since the new loglevel markers were added, there will now be a marker
character at the beginning of the coreboot banner string, and this will
make the existing regular expressions meant to find it fail to match.
This patch fixes the problem by just allowing for a single extra
character there (any character to avoid the hassle of having to match
the marker explicitly). The extra character is optional so that we will
still continue to match banners from older versions of coreboot as well.
Since the `?` glyph is not available in basic POSIX regular expressions,
we have to switch to REG_EXTENDED syntax (should otherwise make no
difference). (Also, move side effects out of assert() while I'm here,
that's not actually safe for the standard libc implementation.)

With LinuxBoot Linux relied on the legacy method of fetching the RSDP
pointer to get ACPI. This uses a more modern approach available since
2018 on the Linux kernel, which involves filling in the zero page.
This method takes precedence over any other method of fetching the
RSDP in Linux (UEFI, Kexec, Legacy/BIOS). Some UEFI zealots are
threatening that legacy code will be removed from Linux so it's best
to already adapt to that possibility.
Tested on Qemu:
- With qemu the RSDP is always in the EBDA, so checking if Linux uses
the provided pointer is better done with a forced bad entry
- With a fake bad pointer Linux correctly does not find RDSP
