Allow boot without unseal of TPM LUKS key
Closes issue #226

Also changed to procedure to show LVM volume groups and block
device ids to aid in choosing the right combination during the
TPM LUKS key sealing process.

Fixed edge case in kernel argument injection
Debian 9 installer doesn't have kernel arguments so the iommu fix

Added rollback protection to generic boot
Changed the checking of required hashes or required rollback state
to be right before boot, allowing the user to sign/set defaults
in interactive mode.

Also cleaned up usages of recovery and fixed iso parameter
regression.

Added the ability to persist a default boot option
Similar to qubes-update, it will save then verify the hashes of
the kexec files. Once TOTP is verified, a normal boot will verify
that the file hashes and all the kexec params match and if
successful, boot directly to OS.

Also added a config option to require hash verification for
non-recovery boots, failing to recovery not met.

Added a generic boot config and persistent params
Refactored boot parsing code and applied that in local-init to
scan /boot for grub options and allow the user to unsafely boot
anything.  This goes a long way to addressing #196.

Optionally the user can customize those boot parameters or enforce
arbitrary hashes on the boot device by creating and signing config
files in /boot/ or /media/ or /media/kexec_iso/ISO_FILENAME/.

adds a USB boot option with basic parsing to kexec
Supports booting from USB media using either the root device or
a signed ISO as the boot device.  Boot options are parsed with
quick/dirty shell scripts to infer kexec params.

Closes #195 and begins to address #196

Rework /init and qubes setup scripts (issue #27, #155, #32, #29, #110)
This adds support for seamless booting of Qubes with a TPM disk key,
as well as signing of qubes files in /boot with a Yubikey.

The signed hashes also includes a TPM counter, which is incremented
when new hashes are signed.  This prevents rollback attacks against
the /boot filesystem.

The TPMTOTP value is presented to the user at the time of entering
the disk encryption keys.  Hitting enter will generate a new code.

The LUKS headers are included in the TPM sealing of the disk
encryption keys.

TPM disk encryption keys for Qubes.
Issue #123: This streamline Qubes startup experience by
making it possible to have a single-password decryption.

Issue #29: The disk keys in `/secret.key` are passed to the systemd
in initramfs through `/etc/crypttab`, which is generated on each boot.
This is slow; need to look at alternate ways.

Issue #110: By using LVM instead of partitions it is now
possible to find the root filesystem in a consistent way.

Issue #80: LVM is now included in the ROM.
