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.

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);

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.

Fixed loading of ACPI tables on EFI (side effect was apparent memory
corruption ranging from unpredictable behavior to system reset).
Reported by Nando Eva <nando4eva@ymail.com>
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.
GPT_BOTH_VALID is 4 bits so simple a boolean check is not sufficient.
This broken condition allowed gptprio to trust bogus disk locations in
headers that were marked invalid causing arbitrary disk corruption.
Add support for adding gpg keys to the trusted database with a new command
called "trust_var". This takes the contents of a variable (in ascii-encoded
hex) and interprets it as a gpg public key.
The getenv code was mishandling the conversion of binary to hex. Grub's
sprintf() doesn't seem to support the full set of format conversions, so
fix this in the nasty way.
Define
* GRUB_EFI_PERSISTENT_MEMORY (UEFI memory map type 14) per UEFI 2.5
* GRUB_MEMORY_PERSISTENT (E820 type 7) per ACPI 3.0
* GRUB_MEMORY_PERSISTENT_LEGACY (E820 unofficial type 12) per ACPI 3.0
and translate GRUB_EFI_PERSISTENT_MEMORY to GRUB_MEMORY_PERSISTENT in
grub_efi_mmap_iterate().
Includes
* adding the E820 names to lsmmap
* handling the E820 types in make_efi_memtype()

PIT isn't available on some of new hardware including Hyper-V. So
use pmtimer for calibration. Moreover pmtimer calibration is faster, so
use it on coreboor where booting time is important.
Based on patch by Michael Chang.
Add a command to read values from the qemu fwcfg store. This allows data
to be passed from the qemu command line to grub.
Example use:
echo '(hd0,1)' >rootdev
qemu -fw_cfg opt/rootdev,file=rootdev
fwconfig opt/rootdev root
Add the descriptions of the “core”, that means no vendorcode or payload,
coreboot time stamps added up to coreboot commit a7d92441 (timestamps:
You can never have enough of them!) [1].
Running `coreboot_boottime` in the GRUB command line interface now shows
descriptions for all time stamps again on the ASRock E350M1.

EBDA layout is not standardized so we cannot assume first two bytes
are length. Neither is it required by ACPI standard. HP 8710W is known
