The current code has issues when sizeof(long) <> sizeof(size_t). The two
types are assumed to be interchangeable and them being different will
cause crashes and endless loops.
This fix limits the maximum chunk size for many of the symmetric ciphers
to 2^30 bytes. This chunk size limits the amount of data that will
be encrypted/decrypted in one lump. The code internally handles block
of data later than the chunk limit, so this will present no difference
to the caller. Any loss of efficiency due to limiting the chunking to
1Gbyte rather than more should be insignificant.

Also rename the OSSL_CIPHER_PARAM_IV_STATE to OSSL_CIPHER_PARAM_UPDATED_IV

The RC4-MD5 ciphersuites were not removing the length of the MAC when
calculating the length of decrypted TLS data. Since RC4 is a streamed
cipher that doesn't use padding we separate out the concepts of fixed
length TLS data to be removed, and TLS padding.

Many of the new types introduced by OpenSSL 3.0 have an OSSL_ prefix,
e.g., OSSL_CALLBACK, OSSL_PARAM, OSSL_ALGORITHM, OSSL_SERIALIZER.
The OPENSSL_CTX type stands out a little by using a different prefix.
For consistency reasons, this type is renamed to OSSL_LIB_CTX.

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.

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.

The new naming scheme consistently usese the `OSSL_FUNC_` prefix for all
functions which are dispatched between the core and providers.
This change includes in particular all up- and downcalls, i.e., the
dispatched functions passed from core to provider and vice versa.
- OSSL_core_ -> OSSL_FUNC_core_
- OSSL_provider_ -> OSSL_FUNC_core_
For operations and their function dispatch tables, the following convention
is used:
Type | Name (evp_generic_fetch(3)) |
---------------------|-----------------------------------|
operation | OSSL_OP_FOO |
function id | OSSL_FUNC_FOO_FUNCTION_NAME |
function "name" | OSSL_FUNC_foo_function_name |
function typedef | OSSL_FUNC_foo_function_name_fn |
function ptr getter | OSSL_FUNC_foo_function_name |

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:
