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.

+=head1 DESCRIPTION
+
+B<EVP_KEYMGMT> is a method object that represents key management
+implementations for different cryptographic algorithms.
+This method object provides functionality to have providers import key
+material from the outside, as well as export key material to the
+outside.
+Most of the functionality can only be used internally and has no
+public interface, this object is simply passed into other functions
+when needed.
+
+EVP_KEYMGMT_fetch() looks for an algorithm within the provider that
+has been loaded into the B<OPENSSL_CTX> given by I<ctx>, having the
+name given by I<algorithm> and the properties given by I<properties>.
+
+EVP_KEYMGMT_up_ref() increments the reference count for the given
+B<EVP_KEYMGMT> I<keymgmt>.
+
+EVP_KEYMGMT_free() decrements the reference count for the given
+B<EVP_KEYMGMT> I<keymgmt>, and when the count reaches zero, frees it.
+
+EVP_KEYMGMT_provider() returns the provider that has this particular
+implementation.
+
+=head1 NOTES
+
+EVP_KEYMGMT_fetch() may be called implicitly by other fetching
+functions, using the same library context and properties.
+Any other API that uses keys will typically do this.
+
+=head1 RETURN VALUES
+
+EVP_KEYMGMT_fetch() returns a pointer to the key management
+implementation represented by an EVP_KEYMGMT object, or NULL on
+error.
+
+EVP_KEYMGMT_up_ref() returns 1 on success, or 0 on error.
+
+EVP_KEYMGMT_free() doesn't return any value.
+
+EVP_KEYMGMT_provider() returns a pointer to a provider object, or NULL
+on error.
