This replaces the older 'file:' loader that is now an engine.
It's still possible to use the older 'file:' loader by explicitly
using the engine, and tests will remain for it as long as ENGINEs are
still supported (even through deprecated).
To support this storemgmt implementation, a few internal OSSL_DECODER
modifications are needed:
- An internal function that implements most of
OSSL_DECODER_CTX_new_by_EVP_PKEY(), but operates on an already
existing OSSL_DECODER_CTX instead of allocating a new one.
- Allow direct creation of a OSSL_DECODER from an OSSL_ALGORITHM.
It isn't attached to any provider, and is only used internally, to
simply catch any DER encoded object to be passed back to the
object callback with no further checking. This implementation
becomes the last resort decoder, when all "normal"
decodation attempts (i.e. those that are supposed to result
in an OpenSSL object of some sort) have failed.
Because file_store_attach() uses BIO_tell(), we must also support
BIO_ctrl() as a libcrypto upcall.
