This function is used to transport private key materia from whatever

If a legacy lower level key has been assigned to the EVP_PKEY, we use

between old style public key types and the EVP_PKEY on providers.

If successful, this function returns a reference to the appropriate

Add basic EVP_KEYMGMT API and libcrypto <-> provider interface

The idea with the key management "operation" is to support the
following set of functionality:

- Key domain parameter generation
- Key domain parameter import
- Key domain parameter export

- Key generation
- Key import
- Key export
- Key loading (HSM / hidden key support)

With that set of function, we can support handling domain parameters
on one provider, key handling on another, and key usage on a third,
with transparent export / import of applicable data.  Of course, if a
provider doesn't offer export / import functionality, then all
operations surrounding a key must be performed with the same
provider.

This method also avoids having to do anything special with legacy
assignment of libcrypto key structures, i.e. EVP_PKEY_assign_RSA().
They will simply be used as keys to be exported from whenever they are
used with provider based operations.

This change only adds the EVP_KEYMGMT API and the libcrypto <->
provider interface.  Further changes will integrate them into existing
libcrypto functionality.

Adapt the provider AES for more use of OSSL_PARAM

The cipher context IV was a bit interesting.  EVP_CIPHER_CTX_iv()
returns a pointer to the live IV, while EVP_CIPHER_CTX_ctrl() with the
type EVP_CTRL_GET_IV gets a copy of the live IV.  To support both, we
support getting it with both the OSSL_PARAM_OCTET_STRING and
OSSL_PARAM_OCTET_PTR datatypes.

Prevent the use of RUN_ONCE inside the FIPS module

FIPS module code *always* runs within the scope of an associated
OPENSSL_CTX. When the module is loaded the OPENSSL_CTX gets created, and
when the module is unloaded the OPENSSL_CX gets freed. A module may be
loaded multiple times within the scope of different OPENSSL_CTX objects.
"Global" data should always be stored within the OPENSSL_CTX. In this
way it will always get cleaned up properly when the module is unloaded.

All current code within the FIPS module works this way. To avoid
"accidents" we disabled the RUN_ONCE code inside the FIPS module.

Adding Test.pm with workaround for Perl abs2rel bug

If SRCTOP != BLDTOP, and SRCTOP is given in relative form, e.g.
"./config ../openssl", then a bug in Perl's abs2rel may trigger that directory-
rewriting in __cwd results in wrong entries in %directories under certain

There should not be any need to go to a higher directory from BLDDIR or SRCDIR,

FIPS module: adapt for the changed error reporting methods

The FIPS module inner provider doesn't need to deal with error reason
strings or error library number, since it uses the outer provider's

Replumbing: re-implement error reporting for providers

The idea is that providers should only have to report a reason code.
The library code is considered to be libcrypto internal, and are
allocated dynamically and automatically for providers on creation.

We reserve the upper 8 bits of the reason code for internal OpenSSL
use.  This allows our own providers to report errors in form of a
packed number that includes library number, function number and
reason number.

With this, a provider can potentially use any reason number it wants
from 1 to 16777216, although the current error semantics really only
allow 1 to 4095 (because only the lower 12 bits are currently
considered an actual reason code by the ERR subsystem).

A provider can provide a reason string table in form of an array of
ERR_STRING_DATA, with each item containing just the reason code and
the associated string, with the dispatch function numbered
OSSL_FUNC_PROVIDER_GET_REASON_STRINGS matching the type
OSSL_provider_get_reason_strings_fn.
If available, libcrypto will call that function on provider
activation.
