Richard Levitte a94a3e0d91 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.
