Added gcryt implementation of RSA algorithm, RSA algorithm
implemented by gcrypt has a higher priority than nettle because
it supports raw padding.

Implement RSA algorithm by hogweed from nettle. Thus QEMU supports
a 'real' RSA backend to handle request from guest side. It's
important to test RSA offload case without OS & hardware requirement.

Introduce new akcipher crypto class 'QCryptoAkCIpher', which supports
basic asymmetric operations: encrypt, decrypt, sign and verify.
Suggested by Daniel P. Berrangé, also add autoptr cleanup for the new
class. Thanks to Daniel!

The ``loaded=on`` option in the command line or QMP ``object-add`` either had
no effect (if ``loaded`` was the last option) or caused options to be
effectively ignored as if they were not given. The property is therefore
useless and was deprecated in 6.0; make it read-only now.
The patch is best reviewed with "-b".

Leading underscores are ill-advised because such identifiers are
reserved. Trailing underscores are merely ugly. Strip both.
Our header guards commonly end in _H. Normalize the exceptions.
Macros should be ALL_CAPS. Normalize the exception.
Done with scripts/clean-header-guards.pl.

The socket API wrappers were initially introduced in commit
00aa0040 ("Wrap recv to avoid warnings"), but made redundant with
commit a2d96af4 ("osdep: add wrappers for socket functions") which fixes
the win32 declarations and thus removed the earlier warnings.

Currently the TLS session object assumes that the caller will always
provide a hostname when using x509 creds on a client endpoint. This
relies on the caller to detect and report an error if the user has
configured QEMU with x509 credentials on a UNIX socket. The migration
code has such a check, but it is too broad, reporting an error when
the user has configured QEMU with PSK credentials on a UNIX socket,
where hostnames are irrelevant.
Putting the check into the TLS session object credentials validation
code ensures we report errors in only the scenario that matters.

Add an implementation of the QEMU cipher APIs to the gnutls
crypto backend. XTS support is only available for gnutls
version >= 3.6.8. Since ECB mode is not exposed by gnutls
APIs, we can't use the private XTS code for compatibility.

This introduces the build logic needed to decide whether we can
use gnutls as a crypto driver backend. The actual implementations
will be introduced in following patches. We only wish to use
gnutls if it has version 3.6.14 or newer, because that is what
finally brings HW accelerated AES-XTS mode for x86_64.

Currently the crypto layer exposes support for a 'des-rfb'
algorithm which is just normal single-DES, with the bits
in each key byte reversed. This special key munging is
required by the RFB protocol password authentication
mechanism.
Since the crypto layer is generic shared code, it makes
more sense to do the key byte munging in the VNC server
code, and expose normal single-DES support.
Replacing cipher 'des-rfb' by 'des' looks like an incompatible
interface change, but it doesn't matter. While the QMP schema
allows any QCryptoCipherAlgorithm for the 'cipher-alg' field
in QCryptoBlockCreateOptionsLUKS, the code restricts what can
be used at runtime. Thus the only effect is a change in error
message.
Original behaviour:
$ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G
Formatting 'demo.luks', fmt=luks size=1073741824 key-secret=sec0 cipher-alg=des-rfb
qemu-img: demo.luks: Algorithm 'des-rfb' not supported
New behaviour:
$ qemu-img create -f luks --object secret,id=sec0,data=123 -o cipher-alg=des-rfb,key-secret=sec0 demo.luks 1G

The built-in AES+XTS implementation is used for the LUKS encryption
When building system emulators it is reasonable to expect that an
external crypto library is being used instead. The performance of the
builtin XTS implementation is terrible as it has no CPU acceleration
support. It is thus not worth keeping a home grown XTS implementation
for the built-in cipher backend.
