used the init function to copy the IV into the hardware causing test failures

Due to a missing else it was setting up the stream for BSAES and then using this incorrect stream with VPAES.
The correct behaviour is not to use VPAES at all in this case.
Also note that the original code in e_aes could set up VPAES and then would overwrite it with the generic implementation.
On a machine that supported both BSAES and VPAES the code was changed locally to force it to run both cases to verify
both paths produce the correct known answers.

The S390x hardware-accelerated cipher implementations keep their IV
state in an internal structure tied to the underlying implementation.
However, the provider itself needs to be able to expose the IV state
to libcrypto when processing the "iv-state" parameter. In the absence
of a S390x hardware-specific get_ctx_params() implementation, be sure
to copy the IV state from the hw-specific structure back to the
generic PROV_CIPHER_CTX object after each cipher operation in order to
synchronize the internal and fetchable state.

The current check for iv_gen and iv_gen_rand only lets you fetch
the IV for the case when it was set internally. It might also make
sense to fetch the IV if one was set at cipher-context creation time,
so switch to checking the iv_state, which should be enough to ensure
that there is valid data in the context to be copied out.

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 internal variables related to the buffering were not being cleared in the init, which meant that the second
update would use the buffered data from the first update.

Calling Init()/Update() and then Init()/Update() again gave a different result when using the same key and iv.
Cipher modes that were using ctx->num were not resetting this value, this includes OFB, CFB & CTR.
The fix is to reset this value during the ciphers einit() and dinit() methods.
Most ciphers go thru a generic method so one line fixes most cases.
Add test for calling EVP_EncryptInit()/EVP_EncryptUpdate() multiple times for all ciphers.
Ciphers should return the same value for both updates.
DES3-WRAP does not since it uses a random in the update.
