422c16e7ec crypt: Fix Lesser GPL version number
There is no "version 2" of the "Lesser" General Public License.
It is either "GPL version 2.0" or "Lesser GPL version 2.1".
This patch replaces all occurrences of "Lesser GPL version 2" with
"Lesser GPL version 2.1" in comment section.

1e0fa32c6c crypto: add testing for unaligned buffers with XTS cipher mode
Validate that the XTS cipher mode will correctly operate with plain
text, cipher text and IV buffers that are not 64-bit aligned.

a61f682fde crypto: refactor XTS cipher mode test suite
The current XTS test overloads two different tests in a single function
making the code a little hard to follow. Split it into distinct test
cases.

8cbfc94269 crypto: rename OUT to out in xts test to avoid clash on MinGW
On MinGW one of the system headers already has "OUT" defined
which causes a compile failure of the test suite. Rename the
test suite var to 'out' to avoid this clash

84f7f180b0 crypto: import an implementation of the XTS cipher mode
The XTS (XEX with tweaked-codebook and ciphertext stealing)
cipher mode is commonly used in full disk encryption. There
is unfortunately no implementation of it in either libgcrypt
or nettle, so we need to provide our own.

The libtomcrypt project provides a repository of crypto
algorithms under a choice of either "public domain" or
the "what the fuck public license".

So this impl is taken from the libtomcrypt GIT repo and
adapted to be compatible with the way we need to call
ciphers provided by nettle/gcrypt.
