In RISC-V we have multiple extensions, that can be
used to accelerate processing.
The known extensions are defined in riscv_arch.def.
From that file test functions of the following
form are generated: RISCV_HAS_$ext().
In recent commits new ways to define the availability
of these test macros have been defined. E.g.:
#define RV32I_ZKND_ZKNE_CAPABLE \
(RISCV_HAS_ZKND() && RISCV_HAS_ZKNE())
[...]
#define RV64I_ZKND_ZKNE_CAPABLE \
(RISCV_HAS_ZKND() && RISCV_HAS_ZKNE())
This leaves us with two different APIs to test capabilities.
Further, creating the same macros for RV32 and RV64 results
in duplicated code (see example above).
This inconsistent situation makes it hard to integrate
further code. So let's clean this up with the following steps:
* Replace RV32I_* and RV64I_* macros by RICSV_HAS_* macros
* Move all test macros into riscv_arch.h
* Use "AND" and "OR" to combine tests with more than one extension
* Rename include files for accelerated processing (remove extension
postfix).
We end up with compile time tests for RV32/RV64 and run-time tests
for available extensions. Adding new routines (e.g. for vector crypto
instructions) should be straightforward.
Testing showed no regressions.

The PROV_R codes can be returned to applications so it is useful
to have some common set of provider reason codes for the applications
or third party providers.

Use of the low level AES functions has been informally discouraged for a
long time. We now formally deprecate them.
Applications should instead use the EVP APIs, e.g. EVP_EncryptInit_ex,
EVP_EncryptUpdate, EVP_EncryptFinal_ex, and the equivalently named decrypt
functions.

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:

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.
