04f64dbc02 Use SPDX license identifiers. 
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.

e5bd99665e Split volume key verification and device activation. 
It makes key verification easier and also allows digest
verification for keys not assigned to device segment
(unbound keys) for more keyslot context types (tokens).

a0587d4307 Avoid integer overflows during memory allocation. 
It is possible to overflow integers during memory allocation with
insanely large "key bytes" specified in a LUKS header.

Although it could be argued to properly validate LUKS headers while
parsing them, it's still a good idea to fix any form of possible
overflow attacks against cryptsetup in these allocation functions.
