crypto: fix build with nettle >= 3.0.0
In nettle 3, cbc_encrypt() accepts 'nettle_cipher_func' instead of
'nettle_crypt_func' and these two differ in 'const' qualifier of the
first argument. The build fails with:
In file included from crypto/cipher.c:71:0:
./crypto/cipher-nettle.c: In function ‘qcrypto_cipher_encrypt’:
./crypto/cipher-nettle.c:154:38: error: passing argument 2 of
‘nettle_cbc_encrypt’ from incompatible pointer type
cbc_encrypt(ctx->ctx_encrypt, ctx->alg_encrypt,
^
In file included from ./crypto/cipher-nettle.c:24:0,
from crypto/cipher.c:71:
/usr/include/nettle/cbc.h:48:1: note: expected
‘void (*)(const void *, size_t, uint8_t *, const uint8_t *)
but argument is of type
‘void (*)( void *, size_t, uint8_t *, const uint8_t *)
To allow both versions, we switch to the new definition and #if typedef
it for old versions.
