As a preparation to test tpm2_key_protector with grub-emu, the new
option, --tpm-device, is introduced to specify the TPM device for
grub-emu so that grub-emu can access an emulated TPM device from
the host.
Since grub-emu can directly access the device on host, it's easy to
implement the essential TCG2 command submission function with the
read/write functions and enable tpm2_key_protector module for grub-emu,
so that we can further test TPM2 key unsealing with grub-emu.

The GRUB emulator is used as a debugging utility but it could also be
used as a user-space bootloader if there is support to boot an operating
system.
The Linux kernel is already able to (re)boot another kernel via the
kexec boot mechanism. So the grub-emu tool could rely on this feature
and have linux and initrd commands that are used to pass a kernel,
initramfs image and command line parameters to kexec for booting
a selected menu entry.
By default the systemctl kexec option is used so systemd can shutdown
all of the running services before doing a reboot using kexec. But if
this is not present, it can fall back to executing the kexec user-space
tool directly. The ability to force a kexec-reboot when systemctl kexec
fails must only be used in controlled environments to avoid possible
filesystem corruption and data loss.

gnulib defines go in config-util.h, and we need to know whether to
provide duplicates in config.h or not.
