73746f0367 Fix hex representation of binary variable contents 
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.

92e46cccf1 Add smbios command 
Incorporate the smbios command from
https://raw.githubusercontent.com/dm0-/gnuxc/master/patches/grub-2.02~beta2-smbios-module.patch
so we can extract the machine UUID and serial number.

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.

d43a5ee651 tsc: Use alternative delay sources whenever appropriate. 
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.

ebb3d958aa fix memory corruption in pubkey filter over network 
grub_pubkey_open closed original file after it was read; it set
io->device to NULL to prevent grub_file_close from trying to close device.
But network device itself is stacked (net -> bufio); and bufio preserved
original netfs file which hold reference to device. grub_file_close(io)
called grub_bufio_close which called grub_file_close for original file.
grub_file_close(netfs-file) now also called grub_device_close which
freed file->device->net. So file structure returned by grub_pubkey_open
now had device->net pointed to freed memory. When later file was closed,
it was attempted to be freed again.

Change grub_pubkey_open to behave like other filters - preserve original
parent file and pass grub_file_close down to parent. In this way only the
original file will close device. We really need to move this logic into
core instead.

Also plug memory leaks in error paths on the way.
