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.
Commit 0113ac2d broke test passphrase mode when
device was in LUKS2 reencryption.
Previously --test-passphrase parameter automatically raised
CRYPT_ACTIVATE_ALLOW_UNBOUND_KEY flag. It did not make sense
when users mostly want to test whether device can be activated by
provided passphrase or not. Raise the aforementioned flag only
if user requested it either by --unbound parameter or when
specific keyslot was selected.
