03a713b7ab verifiers: Framework core
Verifiers framework provides core file verification functionality which
can be used by various security mechanisms, e.g., UEFI secure boot, TPM,
PGP signature verification, etc.

The patch contains PGP code changes and probably they should be extracted
to separate patch for the sake of clarity.

aebe31c375 verifiers: File type for fine-grained signature-verification controlling
Let's provide file type info to the I/O layer. This way verifiers
framework and its users will be able to differentiate files and verify
only required ones.

This is preparatory patch.

e6cc6f328a disk: Update grub_gpt_partentry
Rename grub_gpt_part_type to grub_gpt_part_guid and update grub_gpt_partentry
to use this type for both the partition type GUID string and the partition GUID
string entries.  This change ensures that the two GUID fields are handled more
consistently and helps to simplify the changes needed to add Linux partition
GUID support.

4aeba29569 ls: prevent double open
Prevent a double open.  This can cause problems with some ieee1275
devices, causing the system to hang.  The double open can occur
as follows:

grub_ls_list_files (char *dirname, int longlist, int all, int human)
       dev = grub_device_open (device_name);
       dev remains open while:
       grub_normal_print_device_info (device_name);
                dev = grub_device_open (name);

4bd4a88725 i386, x86_64, ppc: fix switch fallthrough cases with GCC7
In util/getroot and efidisk slightly modify exitsing comment to mostly
retain it but still make GCC7 compliant with respect to fall through
annotation.

In grub-core/lib/xzembed/xz_dec_lzma2.c it adds same comments as
upstream.

In grub-core/tests/setjmp_tets.c declare functions as "noreturn" to
suppress GCC7 warning.

In grub-core/gnulib/regexec.c use new __attribute__, because existing
annotation is not recognized by GCC7 parser (which requires that comment
immediately precedes case statement).

Otherwise add FALLTHROUGH comment.

Closes: 50598

bf127238ee gpt: fix partition table indexing and validation
Portions of the code attempted to handle the fact that GPT entries on
disk may be larger than the currently defined struct while others
assumed the data could be indexed by the struct size directly. This
never came up because no utility uses a size larger than 128 bytes but
for the sake of safety we need to do this by the spec.

c79c59f129 lsefimmap: support persistent memory and other UEFI 2.5 features
This should accompany
	76ce1de740 Translate UEFI persistent memory type

1. Add a string for the EfiPersistentMemory type 14 that was
added in UEFI 2.5.

2. Decode the memory attributes that were added in UEFI 2.5:
* NV (non-volatile)
* MORE_RELIABLE (higher reliable, e.g., mirrored memory in a system
  with partial memory mirroring)
* RO (read-only)

3. Use proper IEC binary units (KiB, MiB, etc.) for power-of-two
values rather than misusing SI power-of-ten units (KB, MB, etc.)

4. The lsmmap command only decodes memory ranges sizes up to GiB scale
units.  Persistent memory ranges will reach into the TiB scale.
Since 64-bit size field supports TiB, PiB, and EiB, decode all of
them for completeness.

5. In the lsefimmap command, rewrite the print statements to
* avoid rounding
* avoid a big nested if/else tree.

For example: In the sixth entry below, the value of 309MB implies
316416KB but is really reporting 316436KB.

Widen the size column to 6 digits to accommodate typical cases.
The worst case value would require 14 digits; if that happens,
let the columns get out of sync.
