Move queue_index, CryptoDevCompletionFunc and opaque into struct
CryptoDevBackendOpInfo, then cryptodev_backend_crypto_operation()
needs an argument CryptoDevBackendOpInfo *op_info only. And remove
VirtIOCryptoReq from cryptodev. It's also possible to hide
VirtIOCryptoReq into virtio-crypto.c in the next step. (In theory,
VirtIOCryptoReq is a private structure used by virtio-crypto only)

Rather than exposing akcipher service/RSA algorithm to virtio crypto
device unconditionally, detect akcipher capability from akcipher

Introduce cryptodev alg type in cryptodev.json, then apply this to
related codes, and drop 'enum CryptoDevBackendAlgType'.
There are two options:
1, { 'enum': 'QCryptodevBackendAlgType',
'prefix': 'CRYPTODEV_BACKEND_ALG',
'data': ['sym', 'asym']}
Then we can keep 'CRYPTODEV_BACKEND_ALG_SYM' and avoid lots of
changes.
2, changes in this patch(with prefix 'QCRYPTODEV_BACKEND_ALG').
To avoid breaking the rule of QAPI, use 2 here.

We have already used qapi to generate crypto device types, this allows

There are two parts in this patch:
1, support akcipher service by cryptodev-builtin driver
2, virtio-crypto driver supports akcipher service
In principle, we should separate this into two patches, to avoid
compiling error, merge them into one.
Then virtio-crypto gets request from guest side, and forwards the
request to builtin driver to handle it.
Test with a guest linux:
1, The self-test framework of crypto layer works fine in guest kernel
2, Test with Linux guest(with asym support), the following script
test(note that pkey_XXX is supported only in a newer version of keyutils):
- both public key & private key
- create/close session
- encrypt/decrypt/sign/verify basic driver operation
- also test with kernel crypto layer(pkey add/query)
All the cases work fine.
Run script in guest:
rm -rf *.der *.pem *.pfx
modprobe pkcs8_key_parser # if CONFIG_PKCS8_PRIVATE_KEY_PARSER=m
rm -rf /tmp/data

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

The Error ** argument must be NULL, &error_abort, &error_fatal, or a
pointer to a variable containing NULL. Passing an argument of the
latter kind twice without clearing it in between is wrong: if the
first call sets an error, it no longer points to NULL for the second
call.
cryptodev_builtin_cleanup() passes @errp to
cryptodev_builtin_sym_close_session() in a loop. Harmless, because
cryptodev_builtin_sym_close_session() can't actually fail. Fix it
anyway.

We already check for queues == 1 in cryptodev_builtin_init and when that
is not true raise an error. But before that error is reported the
assertion in cryptodev_builtin_cleanup kicks in (because object is being
finalized and freed).
Let's remove assert(queues == 1) form cryptodev_builtin_cleanup as it
does only harm and no good.
