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.
