This adds functions which call the mbedtls_aes_crypt_xex function. This
function isn't available yet in mbedTLS, so this is of no use for common
users.
The bright side is, when it's available, it will be supported in
dislocker. A future commit will test for the maybe-existing function and
use our own implementation if it's not existing.
AES-XTS is the new encryption scheme available on Windows 10 (from the
1511 version).
Moreover, this commit remove a branching case which often happens, which
should give beter performances (not tested though).
This adds an include/ directory from which includes files will be. Each
header is now moved to this directory, in the same sub-directory it was
in.
Each #include has been changed accordingly in order not to break
compilation.
