Optional parameter root hash signature is added that can be added to
veritysetup.
The signature file is opened and the signature is added to the keyring.
The kernel will use the signature to validate the roothash.
Usage: veritysetup open <data_device> name <hash_device> <root_hash> --root-hash-signature=<roothash_p7_sig_file>

[Original patch rewritten by Milan Broz]
Other APIs use the root hash in place of keys when using verity
devices, so do the same for crypt_volume_key_get to allow users
to retrieve the root hash of an active verity device.
Use it in veritysetup status to print the root hash.
[Patch slightly modified by Milan Broz]
Almost all the headers in cryptsetup are self-suffienct (in that they
compile on their own). By including <stddef.h>, <stdint.h>, or
<sys/types.h>, all headers will now compile on their own.
This is useful for importing cryptsetup into Bazel/Blaze.
- config.h must always be the first file to be included
- Use AM_CFLAGS and AM_LDFLAGS consistently and properly.

This includes crypto, loopaes, tcrypt handling code I have written myself
and verity code written originally by Mikulas Patocka and modified by me,
copyright by Red Hat.
Other part of library have to stay GPLv2+ only for now
(no agreement from all authors).
Allocate loop device late (only when real block device needed).
Rework underlying device/file access functions.
Move all device (and ioctl) access to utils_device.c.
Allows using file where appropriate without allocation loop device.
