Richard Levitte 9123684c81 Add verbose output to 'openssl list -store-loaders'
The provider based STORE loaders do have settable parameters, so they should
be displayed when '-verbose' is given, just like for any other list.

Out of necessity, this also introduces OSSL_STORE_LOADER_settable_ctx_params()

Nicolas Blais-Miko a0ff819e53 Fix silent error in EVP_CIPHER_CTX_get_updated_iv.
Added new params API function OSSL_PARAM_set_octet_string_or_ptr to only
call the correct setter for OSSL_CIPHER_PARAM_IV and OSSL_CIPHER_PARAM_UPDATED_IV.
Both OSSL_PARAM_set_octet_string and OSSL_PARAM_set_octet_ptr could be called with
only one expected to succeed. This would put a silent error on the error stack when
calling EVP_CIPHER_CTX_get_updated_iv.

Fixes #27117

Ivan Stanković e599893a9f x509: allow SAN URIs to contain userinfo
The way we're currently handling SAN URIs does not allow for userinfo,
meaning the name constraint check on such URIs will fail. Fix this by
skipping over the userinfo component:

      authority   = [ userinfo "@" ] host [ ":" port ]

(per RFC 3986).

Viktor Dukhovni 35f6e7ea02 Make the provider context available to encoders
At the moment the provider context is only available to
encoders that encrypt, but it is useful more generally.

A similar change has already been merged to "master" on the
decoder side, this is the mirror change for encoders.  The
only significant difference is that PEM_ASN1_write_bio needed
to be "extended" (cloned) to allow it to pass the provider context
down to the `k2d` function it uses to encode the data.

I had to "hold my nose" and live with the random "20" added to the data
size in order to accomodate encryption with padding, which may produce
one more cipher block than the input length.  This really should ask
the EVP layer about the block length of the cipher, and allocate the
right amount.  This should be a separate fix for both the old
PEM_ASN1_write_bio() and the new PEM_ASN1_write_bio_ctx().

Richard Levitte e675aabb87 Implement functionality for direct use of composite signature algorithms
The following API groups are extended with a new init function, as well
as an update and final function, to allow the use of explicitly fetched
signature implementations for any composite signature algorithm, like
"sha1WithRSAEncryption":

- EVP_PKEY_sign
- EVP_PKEY_verify
- EVP_PKEY_verify_recover

To support this, providers are required to add a few new functions, not
the least one that declares what key types an signature implementation
supports.

While at this, the validity check in evp_signature_from_algorithm() is
also refactored; the SIGNATURE provider functionality is too complex for
counters.  It's better, or at least more readable, to check function
combinations.
