tls-cipher-suites is an object that is used to inject TLS configuration
into the guest (via fw_cfg). It is never used for host-side TLS
operation, and therefore it need not be available in the tools.

The AES MixColumns and InvMixColumns operations are relatively
expensive 4x4 matrix multiplications in GF(2^8), which is why C
implementations usually rely on precomputed lookup tables rather than
performing the calculations on demand.
Given that we already carry those tables in QEMU, we can just grab the
right value in the implementation of the RISC-V AES32 instructions. Note
that the tables in question are permuted according to the respective
Sbox, so we can omit the Sbox lookup as well in this case.

This commit was created with scripts/clean-includes.
All .c should include qemu/osdep.h first. The script performs three
related cleanups:
* Ensure .c files include qemu/osdep.h first.
* Including it in a .h is redundant, since the .c already includes
it. Drop such inclusions.
* Likewise, including headers qemu/osdep.h includes is redundant.
Drop these, too.

The has_FOO for pointer-valued FOO are redundant, except for arrays.
They are also a nuisance to work with. Recent commit "qapi: Start to
elide redundant has_FOO in generated C" provided the means to elide
them step by step. This is the step for qapi/crypto.json.
Said commit explains the transformation in more detail. The invariant
violations mentioned there do not occur here.

Both the master key and key slot passphrases are run through the PBKDF2
algorithm. The iterations count is expected to be generally very large
(many 10's or 100's of 1000s). It is hard to define a low level cutoff,
but we can certainly say that iterations count should be non-zero. A
zero count likely indicates an initialization mistake so reject it.

The LUKS header data on disk is a fixed size, however, there's expected
to be a gap between the end of the header and the first key slot to get
alignment with the 2nd sector on 4k drives. This wasn't originally part
of the LUKS spec, but was always part of the reference implementation,
so it is worth validating this.

Although the LUKS stripes are encoded in the keyslot header and so

When the user creates a LUKS-encrypted qcow2 image using the qemu-img
program, the passphrase is hashed using PBKDF2 with a dynamic
number of iterations. The number of iterations is determined by
measuring thread cpu time usage, such that it takes approximately
2 seconds to compute the hash.
Because Darwin doesn't implement getrusage(RUSAGE_THREAD), we get an
error message:
> qemu-img: test.qcow2: Unable to calculate thread CPU usage on this platform
for this command:
> qemu-img create --object secret,id=key,data=1234 -f qcow2 -o 'encrypt.format=luks,encrypt.key-secret=key' test.qcow2 100M
