Some modes (e.g., CBC and OFB) update the effective IV with each
block-cipher invocation, making the "IV" stored in the (historically)
EVP_CIPHER_CTX or (current) PROV_CIPHER_CTX distinct from the initial
IV passed in at cipher initialization time. The latter is stored in
the "oiv" (original IV) field, and has historically been accessible
via the EVP_CIPHER_CTX_original_iv() API. The "effective IV" has
also historically been accessible, via both EVP_CIPHER_CTX_iv()
and EVP_CIPHER_CTX_iv_noconst(), the latter of which allows for
*write* access to the internal cipher state. This is particularly
problematic given that provider-internal cipher state need not, in
general, even be accessible from the same address space as libcrypto,
so these APIs are not sustainable in the long term. However, it still
remains necessary to provide access to the contents of the "IV state"
(e.g., when serializing cipher state for in-kernel TLS); a subsequent
reinitialization of a cipher context using the "IV state" as the
input IV will be able to resume processing of data in a compatible
manner.
This problem was introduced in commit
089cb623be, which effectively caused
all IV queries to return the "original IV", removing access to the
current IV state of the cipher.
These functions for accessing the (even the "original") IV had remained
undocumented for quite some time, presumably due to unease about
exposing the internals of the cipher state in such a manner.
Note that this also as a side effect "fixes" some "bugs" where things
had been referring to the 'iv' field that should have been using the
'oiv' field. It also fixes the EVP_CTRL_GET_IV cipher control,
which was clearly intended to expose the non-original IV, for
use exporting the cipher state into the kernel for kTLS.

Some KDF implementations were available before the current EVP_KDF API.
They were used via EVP_PKEY_derive. There exists a bridge between the old
API and the EVP_KDF API however this bridge itself uses a legacy
EVP_PKEY_METHOD. This commit implements a provider side bridge without
having to use any legacy code.

The RAND_DRBG API did not fit well into the new provider concept as
implemented by EVP_RAND and EVP_RAND_CTX. The main reason is that the
RAND_DRBG API is a mixture of 'front end' and 'back end' API calls
and some of its API calls are rather low-level. This holds in particular
for the callback mechanism (RAND_DRBG_set_callbacks()) and the RAND_DRBG
type changing mechanism (RAND_DRBG_set()).
Adding a compatibility layer to continue supporting the RAND_DRBG API as
a legacy API for a regular deprecation period turned out to come at the
price of complicating the new provider API unnecessarily. Since the
RAND_DRBG API exists only since version 1.1.1, it was decided by the OMC
to drop it entirely.
Other related changes:
Use RNG instead of DRBG in EVP_RAND documentation. The documentation was
using DRBG in places where it should have been RNG or CSRNG.
Move the RAND_DRBG(7) documentation to EVP_RAND(7).

To be able to implement this, there was a need for the standard
EVP_PKEY_set1_, EVP_PKEY_get0_ and EVP_PKEY_get1_ functions for
ED25519, ED448, X25519 and X448, as well as the corresponding
EVP_PKEY_assign_ macros. There was also a need to extend the list of
hard coded names that EVP_PKEY_is_a() recognise.
Along with this, OSSL_FUNC_keymgmt_load() are implemented for all

Added Algorithm names AES-128-CBC-CTS, AES-192-CBC-CTS and AES-256-CBC-CTS.
CS1, CS2 and CS3 variants are supported.
Only single shot updates are supported.
The cipher returns the mode EVP_CIPH_CBC_MODE (Internally it shares the aes_cbc cipher code). This
would allow existing code that uses AES_CBC to switch to the CTS variant without breaking code that
tests for this mode. Because it shares the aes_cbc code the cts128.c functions could not be used directly.
The cipher returns the flag EVP_CIPH_FLAG_CTS.
EVP_CIPH_FLAG_FIPS & EVP_CIPH_FLAG_NON_FIPS_ALLOW have been deprecated.

Provide EC serializers for text, pem and der.
EC parameters use ANS1 'CHOICE' - which means they are more embedded than other parameters used by
other KEY types (which normally have a SEQUENCE at the top level).
For this reason the ANS1_STRING type that was being passed around has been changed to a void so that the
code can still be shared with EC.
The EC serializer only supports named curves currently.
NOTE the serializer code assumes PKCS8 format - if the older encode methods are needed they will need to be
added in another PR. (Probably when deserialization is considered).
EVP_PKEY_key_fromdata_init was changed from using a keypair selection to all bits of a key. A side effect of this was
that the very restrictive checks in the ecx code needed to be relaxed as it was assuming all selection flags were non
optional. As this is not the case for any other key the code has been modified.
Fixed a bug in legacy_ctrl_str_to_params() - "ecdh_cofactor_mode" was being incorrectly converted to the wrong keyname.

Aes-ecb mode can be optimized by inverleaving cipher operation on
several blocks and loop unrolling. Interleaving needs one ideal
unrolling factor, here we adopt the same factor with aes-cbc,
which is described as below:
If blocks number > 5, select 5 blocks as one iteration,every
loop, decrease the blocks number by 5.
If 3 < left blocks < 5 select 3 blocks as one iteration, every
loop, decrease the block number by 3.
If left blocks < 3, treat them as tail blocks.
Detailed implementation will have a little adjustment for squeezing
code space.
With this way, for small size such as 16 bytes, the performance is
similar as before, but for big size such as 16k bytes, the performance
improves a lot, even reaches to 100%, for some arches such as A57,
the improvement even exceeds 100%. The following table will list the
encryption performance data on aarch64, take a72 and a57 as examples.
Performance value takes the unit of cycles per byte, takes the format
as comparision of values. List them as below:
