If we call EVP_EncryptUpdate/EVP_DecryptUpdate with length 0 we should
be able to handle it. Most importantly we shouldn't get different
results if we do this compared to if we don't!
An exception is made for CCM mode which has special handling for this in
the low level cipher function.

EVP_CIPHER_CTX_set_keylen() was succeeding even though a bad key length
is passed to it. This is because the set_ctx_params() were all accepting
this parameter and blindly changing the keylen even though the cipher did
not accept a variable key length. Even removing this didn't entirely
resolve the issue because set_ctx_params() functions succeed even if
passed a parameter they do not recognise.
This should fix various issues found by OSSfuzz/Cryptofuzz.

Speed test, aes-siv related cases fail on both x86 and arm.
The return value of siv_init() causes this problem, remove
the iv check to fix it.
Verify it locally, the result is pass.

Fixes#10438
issue found by clusterfuzz/ossfuzz
The dest was getting a copy of the src structure which contained a pointer that should point to an offset inside itself - because of the copy it was pointing to the original structure.
The setup for a ctx is mainly done by the initkey method in the PROV_CIPHER_HW structure. Because of this it makes sense that the structure should also contain a copyctx method that is use to resolve any pointers that need to be setup.
A dup_ctx has been added to the cipher_enc tests in evp_test. It does a dup after setup and then frees the original ctx. This detects any floating pointers in the duplicated context that were pointing back to the freed ctx.

Exporting data from a provider owned domainparams or key is quite an
ordeal, with having to figure out what parameter keys an
implementation supports, call the export function a first time to find
out how large each parameter buffer must be, allocate the necessary
space for it, and call the export function again.
So how about letting the export function build up the key data params
and call back with that? This change implements exactly such a
mechanism.

Not needed any more, since the presence of the OSSL_FUNC_CIPHER_CIPHER
function is enough to tell that there's a custom cipher function.

This involves gcm_cipher() (providers/common/ciphers/cipher_gcm.c),
ccm_cipher() (providers/common/ciphers/cipher_ccm.c), and
tdes_wrap_cipher() (providers/common/ciphers/cipher_tdes_wrap.c)
These are generic implementations of the OSSL_FUNC_CIPHER_CIPHER
function, which returned -1 on error when they should return 0.

From providers/{common,default,legacy}/ to providers/implementations/
However, providers/common/digests/digest_common.c stays where it is,
because it's support code rather than an implementation.
To better support all kinds of implementations with common code, we
add the library providers/libcommon.a. Code that ends up in this
library must be FIPS agnostic.
While we're moving things around, though, we move digestscommon.h
from providers/common/include/internal to providers/common/include/prov,
thereby starting on a provider specific include structure, which
follows the line of thoughts of the recent header file reorganization.
We modify the affected '#include "internal/something.h"' to
'#include "prov/something.h"'.
