This patch switches code to SPDX one-line license identifiers according to
https://spdx.dev/learn/handling-license-info/
and replacing long license text headers.
I used C++ format on the first line in style
// SPDX-License-Identifier: <id>
except exported libcryptsetup.h, when only C comments are used.
The only additional changes are:
- switch backend utf8.c from LGPL2+ to LGPL2.1+ (as in systemd)
- add some additional formatting lines.
String.h and stdbool.h are already included in main backend header,
no need to include them again.
Stdio.h is missing for OpenSSL and NSS backed (for sprintf).
Strings.h is missing for cipher_generic, gcrypt and OpoenSSL (strcasecmp).
Fixes: #885
System FIPS mode check is no longer dependent on /etc/system-fips
file. The change should be compatible with older distributions since
we now depend on crypto backend internal routine.
This commit affects only FIPS enabled systems (with FIPS enabled
builds). In case this causes any regression in current distributions
feel free to drop the patch.

The Argon2i/id is a password hashing function that
won Password Hashing Competiton.
It will be (optionally) used in LUKS2 for passworrd-based
key derivation.
We have to bundle code for now (similar PBKDF2 years ago)
because there is yet no usable implementation in common
crypto libraries.
(Once there is native implementation, cryptsetup
will switch to the crypto library version.)
For now, we use reference (not optimized but portable) implementation.
This patch contains bundled Argon2 algorithm library copied from
https://github.com/P-H-C/phc-winner-argon2

(Or it rehases key in every iteration.)
- Kernel backens seems not to support >20480 HMAC key
- NSS is slow (without proper key reset)
Add some test vectors (commented out by default).
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).
Some backend implementation did reset context by default, so this
should create backend api consistent.
